0 indicates the beginning, +and 1 indicates the end. +The first fraction indicates the first information in the widget +that is visible in the window, and the second fraction indicates +the information just after the last portion that is visible. +.br +Typically the \fBxScrollCommand\fR option consists of the path name +of a \fBscrollbar\fP widget followed by ``set'', e.g. ``.x.scrollbar set''. +This will cause the scrollbar to be updated whenever the view in the +window changes. +.br +If this option is set to the empty string (the default), +then no command is be executed. +.OP \-yscrollcommand yScrollCommand ScrollCommand +A command prefix, used to communicate with vertical scrollbars. +See the description of \fB-xscrollcommand\fP above for details. +.SH "LABEL OPTIONS" +The following options are supported by labels, buttons, +and other button-like widgets: +.OP \-text text Text +Specifies a text string to be displayed inside the widget +(unless overridden by \fB-textvariable\fR). +.OP \-textvariable textVariable Variable +Specifies the name of variable whose value will be used +in place of the \fB-text\fP resource. +.OP \-underline underline Underline +If set, specifies the integer index (0-based) of a character to underline +in the text string. +The underlined character is used for mnemonic activation +(see \fIkeynav(n)\fR). +.OP \-image image Image +Specifies an image to display. +This is a list of 1 or more elements. +The first element is the default image name. +The rest of the list is a sequence of \fIstatespec / value\fR pairs +as per \fBstyle map\fR, specifying different images to use when +the widget is in a particular state or combination of states. +All images in the list should have the same size. +.OP \-compound compound Compound +Specifies how to display the image relative to the text, +in the case both \fB-text\fR and \fB-image\fR are present. +Valid values are: +.RS +.IP text +Display text only. +.IP image +Display image only. +.IP center +Display text centered on top of image. +.IP top +.IP bottom +.IP left +.IP right +Display image above, below, left of, or right of the text, respectively. +.IP none +The default; display the image if present, otherwise the text. +.RE +.OP \-width width Width +If greater than zero, specifies how much space, in character widths, +to allocate for the text label. +If less than zero, specifies a minimum width. +If zero or unspecified, the natural width of the text label is used. + +.SH "COMPATIBILITY OPTIONS" +.OP \-state state State +May be set to \fBnormal\fP or \fBdisabled\fP +to control the \fBdisabled\fP state bit. +This is a ``write-only'' option: setting it changes the +widget state, but the \fBstate\fP widget command does +not affect the state option. + +.SH COMMANDS +.TP +\fIpathName \fBcget\fR \fIoption\fR +Returns the current value of the configuration option given +by \fIoption\fR. +.TP +\fIpathName \fBconfigure\fR ?\fIoption\fR? ?\fIvalue option value ...\fR? +Query or modify the configuration options of the widget. +If one or more \fIoption\-value\fR pairs are specified, +then the command modifies the given widget option(s) +to have the given value(s); +in this case the command returns an empty string. +If \fIoption\fR is specified with no \fIvalue\fR, +then the command returns a list describing the named option: +the elements of the list are the +option name, database name, database class, default value, +and current value. +.\" Note: Ttk widgets don't use TK_OPTION_SYNONYM. +If no \fIoption\fR is specified, returns a list describing all of +the available options for \fIpathName\fR. +.TP +\fIpathName \fBinstate\fR \fIstatespec\fR ?\fIscript\fR? +Test the widget's state. +If \fIscript\fR is not specified, returns 1 if +the widget state matches \fIstatespec\fR and 0 otherwise. +If \fIscript\fR is specified, equivalent to +.CS +if {[\fIpathName\fR instate \fIstateSpec\fR]} \fIscript\fR +.CE +.TP +\fIpathName \fBstate\fR ?\fIstateSpec\fR +Modify or inquire widget state. +If \fIstateSpec\fR is present, sets the widget state: +for each flag in \fIstateSpec\fR, sets the corresponding flag +or clears it if prefixed by an exclamation point. +Returns a new state spec indicating which flags were changed: +.CS +set changes [\fIpathName \fRstate \fIspec\fR] +\fIpathName \fRstate $changes +.CE +will restore \fIpathName\fR to the original state. +If \fIstateSpec\fR is not specified, +returns a list of the currently-enabled state flags. +.SH "WIDGET STATES" +The widget state is a bitmap of independent state flags. +Widget state flags include: +.TP +\fBactive\fR +The mouse cursor is over the widget +and pressing a mouse button will cause some action to occur. +(aka "prelight" (Gnome), "hot" (Windows), "hover"). +.TP +\fBdisabled\fR +Widget is disabled under program control +(aka "unavailable", "inactive") +.TP +\fBfocus\fR +Widget has keyboard focus +.TP +\fBpressed\fR +Widget is being pressed (aka "armed" in Motif). +.TP +\fBselected\fR +"On", "true", or "current" for things like checkbuttons and radiobuttons. +.TP +\fBbackground\fR +Windows and the Mac have a notion of an "active" or foreground window. +The \fBbackground\fP state is set for widgets in a background window, +and cleared for those in the foreground window. +.TP +\fBreadonly\fR +Widget should not allow user modification. +.TP +\fBalternate\fR +A widget-specific alternate display format. +For example, used for checkbuttons and radiobuttons +in the "tristate" or "mixed" state, +and for buttons with \fB-default active\fP. +.TP +\fBinvalid\fP +The widget's value is invalid. +(Potential uses: scale widget value out of bounds, +entry widget value failed validation.) +.PP +A \fIstate specification\fP or \fIstateSpec\fP is a list +of state names, optionally prefixed with an exclamation point (!) +indicating that the bit is off. +.SH EXAMPLES +.CS +set b [ttk::button .b] + +# Disable the widget: +$b state disabled + +# Invoke the widget only if it is currently pressed and enabled: +$b instate {pressed !disabled} { .b invoke } + +# Reenable widget: +$b state !disabled +.CE +.SH "SEE ALSO" +ttk_intro(n), style(n) +.SH KEYWORDS +state, configure, option |
