The +\fBpanedwindow\fR command returns the path name of the new window. +.PP +A panedwindow widget contains any number of panes, arranged +horizontally or vertically, according to the value of the +\fB\-orient\fR option. Each pane contains one widget, and each pair of +panes is separated by a moveable (via mouse movements) sash. Moving a +sash causes the widgets on either side of the sash to be resized. + +.SH "WIDGET COMMAND" +.PP +The \fBpanedwindow\fR command creates a new Tcl command whose name is +the same as the path name of the panedwindow's window. This command +may be used to invoke various operations on the widget. It has the +following general form: +.CS +\fIpathName option \fR?\fIarg arg ...\fR? +.CE +\fIPathName\fR is the name of the command, which is the same as +the panedwindow widget's path name. \fIOption\fR and the \fIarg\fRs +determine the exact behavior of the command. The following +commands are possible for panedwindow widgets: +.TP +\fIpathName \fBadd \fIwindow ?window ...? ?option value ...?\fR +Add one or more windows to the panedwindow, each in a separate pane. +The arguments consist of the names of one or more windows +followed by pairs of arguments that specify how to manage the windows. +\fIOption\fR may have any of the values accepted by the +\fBconfigure\fR subcommand. +.TP +\fIpathName \fBcget \fIoption\fR +Returns the current value of the configuration option given by +\fIoption\fR. \fIOption\fR may have any of the values accepted by the +\fBpanedwindow\fR command. +.TP +\fIpathName \fBconfigure \fI?option? ?value option value ...?\fR +Query or modify the configuration options of the widget. If no +\fIoption\fR is specified, returns a list describing all of the +available options for \fIpathName\fR (see \fBTk_ConfigureInfo\fR for +information on the format of this list). If \fIoption\fR is specified +with no \fIvalue\fR, then the command returns a list describing the +one named option (this list will be identical to the corresponding +sublist of the value returned if no \fIoption\fR is specified). 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. \fIOption\fR may have +any of the values accepted by the \fBpanedwindow\fR command. +.TP +\fIpathName \fBforget \fIwindow ?window ...?\fR +Remove the pane containing \fIwindow\fR from the panedwindow. All +geometry management options for \fIwindow\fR will be forgotten. +.TP +\fIpathName \fBidentify \fIx y\fR +Identify the panedwindow component underneath the point given by +\fIx\fR and \fIy\fR, in window coordinates. If the point is over a +sash or a sash handle, the result is a two element list containing the +index of the sash or handle, and a word indicating whether it is over +a sash or a handle, such as {0 sash} or {2 handle}. If the point is +over any other part of the panedwindow, the result is an empty list. +.TP +\fIpathName \fBproxy \fI?args?\fR +This command is used to query and change the position of the sash +proxy, used for rubberband-style pane resizing. It can take any of +the following forms: +.RS +.TP +\fIpathName \fBproxy coord\fR +Return a list containing the x and y coordinates of the most recent +proxy location. +.TP +\fIpathname \fBproxy forget\fR +Remove the proxy from the display. +.TP +\fIpathName \fBproxy place \fIx y\fR +Place the proxy at the given \fIx\fR and \fIy\fR coordinates. +.RE +.TP +\fIpathName \fBsash \fI?args?\fR +This command is used to query and change the position of sashes in the +panedwindow. It can take any of the following forms: +.RS +.TP +\fIpathName \fBsash coord \fIindex\fR +Return the current x and y coordinate pair for the sash given by +\fIindex\fR. \fIIndex\fR must be an integer between 0 and 1 less than +the number of panes in the panedwindow. The coordinates given are +those of the top left corner of the region containing the sash. +\fIpathName \fBsash dragto \fIindex x y\fR +This command computes the difference between the given coordinates and the +coordinates given to the last \fBsash coord\fR command for the given +sash. It then moves that sash the computed difference. The return +value is the empty string. +.TP +\fIpathName \fBsash mark \fIindex x y\fR +Records \fIx\fR and \fIy\fR for the sash given by \fIindex\fR; used in +conjunction with later dragto commands to move the sash. +.TP +\fIpathName \fBsash place \fIindex x y\fR +Place the sash given by \fIindex\fR at the given coordinates. +.RE +.TP +\fIpathName \fBpanecget \fIwindow option\fR +Query a management option for \fIwindow\fR. \fIOption\fR may be any +value allowed by the \fBpaneconfigure\fR subcommand. +.TP +\fIpathName \fBpaneconfigure \fIwindow ?option? ?value option value ...?\fR +Query or modify the management options for \fIwindow\fR. If no +\fIoption\fR is specified, returns a list describing all of the +available options for \fIpathName\fR (see \fBTk_ConfigureInfo\fR for +information on the format of this list). If \fIoption\fR is specified +with no \fIvalue\fR, then the command returns a list describing the +one named option (this list will be identical to the corresponding +sublist of the value returned if no \fIoption\fR is specified). 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. The following options +are supported: +.RS +.TP +\fB\-after \fIwindow\fR +Insert the window after the window specified. \fIwindow\fR should be the +name of a window already managed by \fIpathName\fR. +.TP +\fB\-before \fIwindow\fR +Insert the window before the window specified. \fIwindow\fR should be +the name of a window already managed by \fIpathName\fR. +.TP +\fB\-height \fIsize\fR +Specify a height for the window. The height will be the outer +dimension of the window including its border, if any. If \fIsize\fR +is an empty string, or if \fB\-height\fR is not specified, then the +height requested internally by the window will be used initially; the +height may later be adjusted by the movement of sashes in the +panedwindow. \fISize\fR may be any value accepted by \fBTk_GetPixels\fR. +.TP +\fB\-minsize \fIn\fR +Specifies that the size of the window cannot be made less than +\fIn\fR. This constraint only affects the size of the widget in the +paned dimension -- the x dimension for horizontal panedwindows, the y +dimension for vertical panedwindows. May be any value accepted by +\fBTk_GetPixels\fR. +.TP +\fB\-padx \fIn\fR +Specifies a non-negative value indicating how much extra space to +leave on each side of the window in the X-direction. The value may +have any of the forms accepted by \fBTk_GetPixels\fR. +.TP +\fB\-pady \fIn\fR +Specifies a non-negative value indicating how much extra space to +leave on each side of the window in the Y-direction. The value may +have any of the forms accepted by \fBTk_GetPixels\fR. +.TP +\fB\-sticky \fIstyle\fR +If a window's pane is larger than the requested dimensions of the +window, this option may be used to position (or stretch) the window +within its pane. \fIStyle\fR is a string that contains zero or more +of the characters \fBn\fP, \fBs\fP, \fBe\fP or \fBw\fP. The string +can optionally contains spaces or commas, but they are ignored. Each +letter refers to a side (north, south, east, or west) that the window +will "stick" to. If both \fBn\fP and \fBs\fP (or \fBe\fP and \fBw\fP) +are specified, the window will be stretched to fill the entire height +(or width) of its cavity. +.TP +\fB\-width \fIsize\fR +Specify a width for the window. The width will be the outer +dimension of the window including its border, if any. If \fIsize\fR +is an empty string, or if \fB\-width\fR is not specified, then the +width requested internally by the window will be used initially; the +width may later be adjusted by the movement of sashes in the +panedwindow. \fISize\fR may be any value accepted by \fBTk_GetPixels\fR. +.RE +.TP +\fIpathName \fBpanes\fR +Returns an ordered list of the widgets managed by \fIpathName\fR. + +.SH "RESIZING PANES" + +A pane is resized by grabbing the sash (or sash handle if present) and +dragging with the mouse. This is accomplished via mouse motion +bindings on the widget. When a sash is moved, the sizes of the panes +on each side of the sash, and thus the widgets in those panes, are +adjusted. +.PP +When a pane is resized from outside (eg, it is packed to expand and +fill, and the containing toplevel is resized), space is added to the final +(rightmost or bottommost) pane in the window. + +.SH KEYWORDS +panedwindow, widget, geometry management |
