The default is 10 pixels. .LP .nf Name: \fBorient\fR Class: \fBOrient\fR Command-Line Switch: \fB-orient\fR .fi .IP Specifies the orientation of the separators: \fBvertical\fR or \fBhorizontal\fR. The default is horizontal. .LP .nf Name: \fBsashBorderWidth\fR Class: \fBBorderWidth\fR Command-Line Switch: \fB-sashborderwidth\fR .fi .IP Specifies a value indicating the width of the 3-D border to draw around the outside of the sash in any of the forms acceptable to \fBTk_GetPixels\fR. The default is 2 pixels. .LP .nf Name: \fBsashCursor\fR Class: \fBCursor\fR Command-Line Switch: \fB-sashcursor\fR .fi .IP Specifies the type of cursor to be displayed in the sash. The default is crosshair. .LP .nf Name: \fBsashHeight\fR Class: \fBHeight\fR Command-Line Switch: \fB-sashheight\fR .fi .IP Specifies the height of the sash in any of the forms acceptable to \fBTk_GetPixels\fR. The default is 10 pixels. .LP .nf Name: \fBsashIndent\fR Class: \fBSashIndent\fR Command-Line Switch \fBsashindent\fR .fi .IP Specifies the placement of the sash along the panes in any of the forms acceptable to \fBTk_GetPixels\fR. A positive value causes the sash to be offset from the near (left/top) side of the pane, and a negative value causes the sash to be offset from the far (right/bottom) side. If the offset is greater than the width, then the sash is placed flush against the side. The default is -10 pixels. .LP .nf Name: \fBsashWidth\fR Class: \fBWidth\fR Command-Line Switch: \fB-sashwidth\fR .fi .IP Specifies the width of the sash in any of the forms acceptable to \fBTk_GetPixels\fR. The default is 10 pixels. .LP .nf Name: \fBshowHandle\fR Class: \fBShowHandle\fR Command-Line Switch: \fB-showhandle\fR .fi .IP Specifies whether or not to display the sashes on the window panes. The default is 1, and valid options are 0 and 1. .LP .nf Name: \fBthickness\fR Class: \fBThickness\fR Command-Line Switch: \fB-thickness\fR .fi .IP Specifies the thickness of the separators in any of the forms acceptable to \fBTk_GetPixels\fR. The default is 3 pixels. .LP .LP .nf Name: \fBwidth\fR Class: \fBWidth\fR Command-Line Switch: \fB-width\fR .fi .IP Specifies the overall width of the paned window in any of the forms acceptable to \fBTk_GetPixels\fR. The default is 10 pixels. .LP .BE .SH DESCRIPTION .PP The \fBiwidgets::panedwindow\fR command creates a multiple paned window widget capable of orienting the panes either vertically or horizontally. Each pane is itself a frame acting as a child site for other widgets. The border separating each pane contains a sash which allows user positioning of the panes relative to one another. .SH "METHODS" .PP The \fBiwidgets::panedwindow\fR command creates a new Tcl command whose name is \fIpathName\fR. This command may be used to invoke various operations on the widget. It has the following general form: .DS C \fIpathName option \fR?\fIarg arg ...\fR? .DE \fIOption\fR and the \fIarg\fRs determine the exact behavior of the command. .PP Many of the widget commands for the \fBpanedwindow\fR take as one argument an indicator of which pane of the paned window to operate on. These indicators are called \fIindexes\fR and allow reference and manipulation of panes regardless of their current map state. Paned window indexes may be specified in any of the following forms: .TP 12 \fInumber\fR Specifies the pane numerically, where 0 corresponds to the nearest (top/left-most) pane of the paned window. .TP 12 \fBend\fR Indicates the farthest (bottom/right-most) pane of the paned window. .TP 12 \fIpattern\fR If the index doesn't satisfy one of the above forms then this form is used. \fIPattern\fR is pattern-matched against the tag of each pane in the panedwindow, in order from left/top to right/left, until a matching entry is found. The rules of \fBTcl_StringMatch\fR are used. .SH "WIDGET-SPECIFIC METHODS" .TP \fIpathName \fBadd\fR \fItag\fR ?\fIoption value option value\fR? Adds a new pane to the paned window on the far side (right/bottom). The following options may be specified: .RS .TP \fB-margin\fR \fIvalue\fR Specifies the border distance between the pane and pane contents is any of the forms acceptable to \fBTk_GetPixels\fR. The default is 8 pixels. .TP \fB-minimum\fR \fIvalue\fR Specifies the minimum size that a pane's contents may reach not inclusive of twice the margin in any of the forms acceptable to \fBTk_GetPixels\fR. The default is 10 pixels. The \fBadd\fR method returns the path name of the pane. .RE .TP \fIpathName \fBcget\fR \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 \fBiwidgets::panedwindow\fR command. .TP \fIpathName \fBchildsite\fR ?\fIindex\fR? Returns a list of the child site path names or a specific child site given an index. The list is constructed from the near side (left/top) to the far side (right/bottom). .TP \fIpathName\fR \fBconfigure\fR ?\fIoption\fR? ?\fIvalue 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 \fBiwidgets::panedwindow\fR command. .TP \fIpathName \fBdelete\fR \fIindex\fR Deletes a specified pane given an \fIindex\fR. .TP \fIpathName \fBfraction\fR \fIpercentage\fR \fIpercentage\fR ?\fIpercentage percentage ...\fR? Sets the visible percentage of the panes. Specifies a set of percentages which are applied to the visible panes from the near side (left/top). The number of percentages must be equal to the current number of visible (mapped) panes and add up to 100. .TP \fIpathName \fBhide\fR \fIindex\fR Changes the visiblity of the specified pane, allowing a previously displayed pane to be visually removed rather than deleted. .TP \fIpathName \fBindex\fR \fIindex\fR Returns the numerical index corresponding to index. .TP \fIpathName \fBinsert \fIindex\fR \fItag\fR ?\fIoption value option value ...\fR? Same as the \fBadd\fR command except that it inserts the new pane just before the one given by \fIindex\fR, instead of appending to the end of the panedwindow. The \fIoption\fR, and \fIvalue\fR arguments have the same interpretation as for the \fBadd\fR widget command. .TP \fIpathName \fBpaneconfigure\fR \fIindex\fR ?\fIoptions\fR? This command is similar to the \fBconfigure\fR command, except that it applies to the options for an individual pane, whereas \fBconfigure\fR applies to the options for the paned window as a whole. \fIOptions\fR may have any of the values accepted by the \fBadd\fR widget command. If \fIoptions\fR are specified, options are modified as indicated in the command and the command returns an empty string. If no \fIoptions\fR are specified, returns a list describing the current options for entry \fIindex\fR (see \fBTk_ConfigureInfo\fR for information on the format of this list). .TP \fIpathName \fBreset\fR Redisplays the pane window using default percentages. .TP \fIpathName \fBshow\fR \fIindex\fR Changes the visiblity of the specified pane, allowing a previously hidden pane to be displayed. .SH "NOTES" .IP Dynamic changing of the margin and or minimum options to values which make the current configuration invalid will block subsequent sash movement until the fractions are modified via the fraction method. For example a panedwindow is created with three panes and the minimum and margin options are at their default settings. Next the user moves the sashes to compact the panes to one side. Now, if the minimum is increased on the most compressed pane via the paneconfigure method to a large enough value, then sash movement is blocked until the fractions are adjusted. This situation is unusual and under normal operation of the panedwindow, this problem will never occur. .LP .SH EXAMPLE .DS package require Iwidgets 4.0 iwidgets::panedwindow .pw -width 300 -height 300 .pw add top .pw add middle -margin 10 .pw add bottom -margin 10 -minimum 10 pack .pw -fill both -expand yes foreach pane [.pw childSite] { button $pane.b -text $pane -relief raised -borderwidth 2 pack $pane.b -fill both -expand yes } .pw fraction 50 30 20 .pw paneconfigure 0 -minimum 20 .pw paneconfigure bottom -margin 15 .DE .SH ACKNOWLEDGEMENTS: .LP Jay Schmidgall .IP 1994 - Base logic posted to comp.lang.tcl .LP Joe Hidebrand .IP 07/25/94 - Posted first multipane version to comp.lang.tcl .LP .IP 07/28/94 - Added support for vertical panes .LP Ken Copeland .IP 09/28/95 - Smoothed out the sash movement and added squeezable panes. .LP .SH AUTHOR Mark L.
