By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11.

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions.

If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices.

Interface Specification For The HTML Widget

+ +

This is a draft interface specification for the Tk HTML +widget currently under development. +Since it is still a draft, it is subject to change. +Eventually, the interface will stabilize and this interface +specification will morph into a manual page.

+ +

Configuration Options

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
-appletcommand +

This option specifies the name of the Tcl procedure to invoke when the + <applet>...</applet> tag sequence is seen. The html + widget will append two arguments to the procedure before calling it. + The first argument is the name of a widget that the callback should + create to hold the applet. + The second argument is + a list of name/value pairs which are the arguments to + the <applet> tag.

+ +

The text between <applet> and </applet> + is normally suppressed. + However, if the -appletcommand option is set to the empty string, + the <applet> tag is ignored and all text between + <applet> and </applet> is displayed + normally.

+ +

"<embed>" is treated as an alias for + "<applet></applet>".

+
-background +

The background color for the widget.

+ +

Note that the <body bgcolor=...> HTML tag does not + automatically cause the widget to change its background color. If + you want the background color to change in response to this HTML tag, + then your Tcl script should intercept + the <body> tag using the + ``token handler'' widget command (described below) and + change the background color manually.

+
-base +

The base URI for the current document. This should be set to + the URI that was used to retrieve the document before parsing + begins.

+
-bdAn alias for -borderwidth + +
-bgAn alias for -background + +
-borderwidth +

The width of the 3-D border drawn around the parameter of the widget, in + pixels.

+
-cursor +

The cursor displayed when the pointer is positioned over the HTML widget. + If {}, the cursor reverts to its default shape.

+
-exportselection
-fontcommand +

The name of a TCL procedure that is used to convert HTML font names + into TCL font names. A default built-in procedure is used if the value + of this option is {}.

+ +

When the HTML widget needs a new font, it calls this procedure with + two arguments. This first argument is the font size expressed as an + integer between 1 and 7. The standard size is 4. The second argument + is a set of between 0 and 3 keywords drawn from the following set: + "bold", "italic", and "fixed". If the "bold" keyword is present in + the second argument, the font returned should be bold. If the "italic" + keyword is present, the font should be italic. If the "fixed" keyword + is present, the font should be fixed-width. The TCL procedure should + return the name of the TCL font that the HTML widget will use to render + the given HTML font. If the TCL procedure returns an empty string, + then the built-in default procedure is used to determine the font.

+ +

Examples: This is {4 {}}. This is {4 fixed}. + This is {3 {}}. This is {5 {fixed bold}} +

+
-fgAn alias for -foreground.
-foreground + The default foreground color in which HTML text is rendered. + The HTML can override this using the color=... attribute + on various HTML tags. +
+-formcommand string + +Declares a handler for everything to do with forms within a document. +Arguments will be appended to string and the result evaluated +during parsing (for form creation) and when the widget is cleared (for +form cleanup). The first argument is a token for +identifying a form. The second argument selects the action to perform. +The remaining arguments depend on the action, as follows. + +
string token form URL method attrs +
The handler should begin taking notes for form token, +especially the (resolved) URL of the action and the +method to be applied. The raw attributes of the FORM element +are in the pairlist attrs. + +
string token flush +
When the document is cleared, the widget will destroy all the windows +it requested. This handler should clean up anything else +it created for that form. + +
string token input path attrs +
The handler should create a window named path +appropriate for the element described by the attrs. +The widget will map the window into its rendering appropriately. +

It is not an error for the handler to return without creating such a window +(it's natural in the case of type=hidden); the widget simply +ignores the element in that case. +The attributes are the raw values in the HTML, with one exception; +a src will be resolved before the handler is called. + +

string token textarea path attrs initial +
The handler should create a window (a single Text, or a Frame with Text +and Scrollbars, or whatever) appropriate for a <textarea> and +initialise it to the initial string. + +
string token select path attrs choices initial +
<select> is quite a complicated case... +The handler should create a window +appropriate for a <select> of the given attributes and +present the list of choices. Each choice is a pair, the +value and its label. initial is a list of values initially +selected. This approach is somewhat questionable but should do +most of the time. +
+ +Caution: Be very careful to avoid confusing HTML variables with TCL +variables. It may be tempting to use the name attribute +fairly directly to link +together related widgets, but it will likely cause incorrect +behaviours. Also be careful to observe the order in which the elements are +created; this determines the order in which they must be submitted. +A default form handler with the correct bahaviour written in TCL will be +bundled with the widget. +

The attribute names will be downcased within attrs. +

-framecommand +The script specified by this option is invoked when the HTML parser +encounters a <frameset>...</frameset> tag sequence. +The arguments to the script are TBD. +If the value of the option is the empty string, then the text within +the <noframe>...</noframe> tag sequence is displayed. + +
-height +Specifies the height of the area into which HTML is rendered. +This value plus twice the -padx, -borderwidth and +-highlightthickness values is the total height of the widget. + +
-highlightbackground + +
-highlightcolor + +
-highlightthickness + +
-hyperlinkcommand + The script specified by this option is invoked whenever the user + clicks on a hyperlink on the HTML page. Before invoking this + script, the URI for the hyperlink is appended. +
-imagecommand + When a ``<img src=...>'' tag is encountered, the + HTML widget invokes the script specified by this option in order to + get the name of a Tk image object to display the HTML image. + Before invoking the script, the following arguments are appended: +
    +
  1. The value of the src=... parameter after have been + processed by the resolver. +
  2. The value of the width=... parameter. +
  3. The value of the height=... parameter. +
  4. A list containing the names and values of all parameters. +
+ If the name returned by this script is the empty string, or if the + script is an empty string, then the HTML widget displays the + alt=... text of the <img> tag instead of + an image. +
-isvisitedcommand +When the HTML widget encounters a hyperlink +(``<a href=...>'') it invokes the script specified +by this option in order to determine whether or not the hyperlink +has been visited. +This information is needed to determine what color to use to display +the hyperlink. + +
-padx +The amount of extra space to insert between the 3-D border and the +left and right sides of the document text. + +
-pady +The amount of extra space to insert between the 3-D border and the top +and bottom of the document text. + +
-relief +The relief used to draw the 3-D border. + +
-resolvercommand +

The name of a TCL command used to resolve URIs. If blank, a built-in + resolver is used. If a TCL command is specified but it returns + an empty string, the built-in resolver is used then too. + The build-in resolver is based on the algorithm + in section 5.2 of RFC 2396.

+ +

Multiple URIs are appended to the TCL command before it is executed. + The first URI is the BASE URI of the document (the URL that specified + by the -base configuration option and updated according to any prior + <BASE> markup). Zero or more additional URIs are + appended to this base. The result of the script should be the resolution + of the whole series or URIs.

+
-rulerelief +

Determines the appearance of the Horizontal Rule (<HR>) markup. + The default is "sunken". This can also be "raised" or "flat". If + "flat", then the <HR> is drawn using a solid line in the current + foreground color. "groove" and "ridge" are the same as "flat".

+
-scriptcommand +

Whenever <SCRIPT>...</SCRIPT> markup is encountered in + the input HTML, the attributes of the <SCRIPT> markup and + the body of the script are appended to this string and the result + is executed as a TCL command. If this options is the empty string, + then the script is ignored. +

-selectioncolor +The background color used when drawing the selection. The +foreground color for the selection is the same as the regular +foreground color. + +
-tablerelief +

Determines the appearance of the borders around tables. + The default is "raised". This can also be "sunken" or "flat". If + "flat", then the borders is drawn using solid lines in the current + foreground color. "groove" and "ridge" are the same as "flat".

+
-takefocus + +
-unvisitedcolor +The foreground color used to draw hyperlinks that have not been visited. + +
-underlinehyperlinks +Set to TRUE to cause hyperlinks to be drawn using an underlined font. + +
-visitedcolor +The foreground color used to draw hyperlinks that have been visited. + +
-width +The width of the document text. +This value does not include space allocated for +-highlightthickness, -borderwiddth or +-padx. + +
-xscrollcommand + +
-yscrollcommand + +
+ +

Indices

+ +Internally, the HTML widget stores the HTML document as a list of +tokens. +Each token is either +
    +
  • a contiguous sequence of non-space characters (Text), +
  • a contiguous sequence of spaces, tabs or newlines (Space), +
  • or an HTML markup tag (such as ``<em>''.) +
+Tokens are identified by number. +The first token is ``1'', the second is ``2'' and so forth. +So in its simplest form, an index is just an integer greater than 0. +

+Within a single Text or Space token, individual characters are +also identified by number, though the counting starts with 0 instead +of 1. +The character number is connected to the token number by a period. +So, for example, the 4th character in the 9th token would be +``9.3''. +

+Two integers separated by a dot is called the connonical form +of an index. +Other index forms are available, including: + + +
end +The keyword ``end'' means one character past +the last character of the last token. +
@X,Y +The character located at screen coordinates X,Y. +
*.last +The second integer can be replaced by the keyword ``last'' to mean the +last character in the token. +
sel.first +This is the first character that is part of the selection. +
sel.last +This is the last character that is part of the selection. +
ins +The character immediately following the insertion cursor. +
+ +

Commands

+ +
+
html window ?options ...?

+

+ Create a new HTML widget instance named windows +
+

+

html reformat from to text

+

+Convert text from one encoding to another. The text is given +in the text argument. The current encoding of the text +is specified by the from argument. This command returns +the same text in the to encoding. +

+From and to may be any of the following values: +

+ + + + + + + + + +
plain + Ordinary text with no characters escaped. +
http + The text is encoded in a form suitable for use with the HTTP + protocol. Spaces are converted to "+". Special characters + and escaped as "%aa" where "a" is a hexadecimal digit. A special + character is anything other than an alphanumeric or one of these: + ".", "$", "-", or "_". +
url + The text is encoded in a form suitable for use as a URI. + Spaces are converted to "+". Special characters + and escaped as "%aa" where "a" is a hexadecimal digit. A special + character is anything other than an alphanumeric or one of these: + ".", "$", "-", "_", or "/". +
html + The text is encoded in a form suitable for use within HTML. + "&" is encoded as "&amp;", "<" is encoded as "&lt;" and so + forth. +
+

+This command is intended to be useful to the TCL procedures that implement +callbacks for the HTML widget. +

+

+

html uri join scheme authority path query fragment

+

+This command takes the five main components of a URI and joins them together +into a complete URI. Special characters in any component are escaped. +
+

+

html uri split uri

+

+This command takes a single URI and splits it into its five major +components: scheme, authorithy, path, query and fragement. The command +returns a list where each component is an element of the list. +Components missing from the URI are represented as empty elements in +the list. +
+ +
+ +

Widget Commands

+ +
+ +
WIDGET  cget config-option

+

+Return the value of a configuration option. Works just like any +other Tk widget. +

+ +

WIDGET  clear

+

+Remove all tokens and text from the HTML widget. +The parser is reset to its initial state. +This routine should be called to changes pages. +

+ +

WIDGET  configure ?args...?

+

+The standard Tk configuration command. +

+ +

WIDGET  href  X  Y

+

If the coordinates X Y define a point above a hyperlink, +then this command will return the target URL for that hyperlink. +The URL will be resolved using the -resolvercommand before it +is returned. +

+ +

WIDGET  index  INDEX  ?COUNT  UNITS?

+
+Translates INDEX into its connonical form. +The connonical form of an index is two integers separated by a period. +

+The optional 3rd and 4th arguments specify a displacement from INDEX +to the value of the index returned. +COUNT can be any integer value, including a negative number. +UNITS must be either ``char'' or ``line''. +

+ +

WIDGET  insert  INDEX

+

+Causes the insertion cursor (a flashing vertical bar) to be positioned +immediately before the character specified by INDEX. +

+ +

WIDGET  names

+

+This command causes the widget to scan the entire text of the document +looking for tags of the form ``<a name=...>''. +It returns a list of values of the name=... fields. +

+The vertical position of the document can be moved to any of these names +using the ``WIDGET yview NAME'' command described +below. +

+ +

WIDGET  parse  HTML-TEXT

+

Adds the given HTML text to the end of any text previously received +through the parse command and parses as much of the text as +possible into tokens. +Afterwards, the display is updated to show the new tokens, if they are +visible.

+ +

WIDGET  resolver  ?uri ...?

+

The resolver specified by the -resolvercommand option + is called with the + base URI of the document followed + by the remaining arguments to this commant. The result of this + command is the result of the -resolvercommand script.

+ +

WIDGET  selection  subcommand args...

+

The selection widget command is used to control the selection.

+

+
WIDGET  selection clear

+

Clear the current selection. No text will be selected after this + command executes.

+ +

WIDGET  selection set  START  END

+

Change the selection to be all text contained within the given + indices.

+

+

+ +

WIDGET  text  subcommand args...

+

There are several token commands. They all have the common +property that they directly manipulate the text that is displayed. +These commands (none of which are currently implemented) can be used +to build an WYSIWYG editor for HTML.

+

+
WIDGET  text ascii  INDEX-1  INDEX-2

+

+ Returns plain ASCII text that represents all characters between + INDEX-1 and INDEX-2. Formatting tags are omitted. + The INDEX-1 character is included by INDEX-2 is omitted. +

+ +

WIDGET  text delete  INDEX-1  INDEX-2

+

+ All text from INDEX-1 up to, but not including INDEX-2 is + removed and the display is updated accordingly. +

+ +

WIDGET  text html  INDEX-1  INDEX-2

+

+ Returns HTML text that represents all characters and formatting tags + between INDEX-1 and INDEX-2. + The INDEX-1 character is included by INDEX-2 is omitted. +

+ +

WIDGET  text insert  INDEX  TEXT

+

+ Inserts one or more characters immediately before the character whose + index is given. +

+

+ + +
WIDGET  token  subcommand args...

+

There are several token commands. They all have the common + property that they involve the list of tokens into which the + HTML is parsed.

+ Some of the following subcommands make use of indices. The + character number of these indices is ignored since these commands + deal only with whole tokens. +

+

+
WIDGET  token append  + TAG  ARGUMENTS

+

+ The command causes a token to be appended to the current list of + tokens in the HTML widget. This command is typically used within + a token handler. +

+ + +

WIDGET  token delete  + INDEX  ?INDEX-2?

+

+ Deletes the single token indentified by the index. If a second index is + given, the range of tokens from the first to the second index inclusive + is deleted. +

+ +

WIDGET  token find  + TAG

+

+ Locates all tokens with the given TAG and returns them all + as a list. + Each element of the returned list is a sublist containing the index + for the token and the arguments for the token. +

+ +

WIDGET  token get  + INDEX  ?INDEX-2?

+

+ Returns a list of tokens in the range of INDEX through + INDEX-2. + Each element of the list consists of the token tag followed by + the token arguments. +

+ +

WIDGET  token handler  + TAG  ?SCRIPT?

+

+ This command allows special processing to occur for selected tokens + in the HTML input stream. + The TAG argument is either ``Text'' or ``Space'' or the name + of an HTML tag (ex: ``H3'' or ``/A''). + If a non-empty script is specified for a particular tag, then when + instances of that tag are encountered by the parser, the parser calls the + corresponding script instead of appending the token to the end of the + token list. Before calling the script, three arguments are appended: +
    +
  1. The token number. +
  2. The tag. (ex: H3) +
  3. A list of name/value pairs describing all arguments to the tag. +
+ An empty handler script causes the default processing to occur for + the tag. If the script argument is omitted all together, then + the current value of the token handler for the given tag is returned. +

+ Only one handler may be defined for each token type. If a new + handler is specified for a token type that previously had a different + handler defined, then the old handler is overwritten by the new. +

+ +

WIDGET  token insert  + INDEX  TAG  ARGUMENTS

+

+ Inserts a single token given by TAG and ARGUMENTS into + the token list immediately before INDEX. +

An HTML Widget For Tcl/Tk

" +puts $f { +

"Tkhtml" is a Tcl/Tk widget that displays HTML. Tkhtml +is implemented in C. It is a true widget, not a metawidget implemented +using the Text or Canvas widgets of the Tcl/Tk core. Implementing +Tkhtml in C gives it a number of advantages:

+ +

+

    +
  • It runs fast and uses little memory.
    • +
  • It supports smooth scrolling.
    • +
  • It supports text wrap-around on images and tables.
    • +
  • It has a full implementation of tables. Complex pages (such as + http://www.scriptics.com/) + are displayed correctly.
    • +
  • Supports forms.
    • +
  • It supports the <APPLET>, <SCRIPT> and <EMBED>. + (Partially. Full support is pending.)
    • +
  • Support for frames is planned.
    • +
+

+ +

Tkhtml can be used with Tcl/Tk8.0 or later. +The shared libraries use the new stubs mechanism, so you +should be able to load Tkhtml with any version of "wish" beginning +with 8.0.6.

+ +

At the moment, there is not a lot of software that uses this +widget. Tkhtml is not an application in and of itself. It is only +a tool. But applications are being built around tkhtml. Check back +later for new developments.

Getting The Widget

+ +

Visit the download page for a list of +files available for immediate download.

+ +

You can now also obtain the latest tkhtml sources via anonymous CVS. +To access the anonymous CVS server, first install CVS on your system. +(See http://www.cyclic.com/ for +additional information.) Then login as follows:

+ +
+cvs -d :pserver:cvs@xoli.dyn.dhs.org:/home/cvs/cvsroot login
+
+ +

You will be prompted for a password. Use "cvs". After +you get logged in successfully, you can check out the source tree +like this:

+ +
+cvs -d :pserver:cvs@xoli.dyn.dhs.org:/home/cvs/cvsroot checkout htmlwidget
+
+ +

This command creates a directory named "htmlwidget" and +fills it with the latest version of the sources.
