See the options manual entry for details on the standard op-

tions.

Name: height

Class: Height

Command-Line Switch: -height

Specifies the overall height of the paned window in any of the

forms acceptable to Tk_GetPixels. The default is 10 pixels.

Name: orient

Class: Orient

Command-Line Switch: -orient

Specifies the orientation of the separators: vertical or horizon*-

tal. The default is horizontal.

Name: sashBorderWidth

Class: BorderWidth

Command-Line Switch: -sashborderwidth

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

Tk_GetPixels. The default is 2 pixels.

Name: sashCursor

Class: Cursor

Command-Line Switch: -sashcursor

Specifies the type of cursor to be displayed in the sash. The

default is crosshair.

Name: sashHeight

Class: Height

Command-Line Switch: -sashheight

Specifies the height of the sash in any of the forms acceptable

to Tk_GetPixels. The default is 10 pixels.

Name: sashIndent

Class: SashIndent

Command-Line Switch sashindent

Specifies the placement of the sash along the panes in any of the

forms acceptable to Tk_GetPixels. 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.

Name: sashWidth

Class: Width

Command-Line Switch: -sashwidth

Specifies the width of the sash in any of the forms acceptable to

Tk_GetPixels. The default is 10 pixels.

Name: showHandle

Class: ShowHandle

Command-Line Switch: -showhandle

Specifies whether or not to display the sashes on the window

panes. The default is 1, and valid options are 0 and 1.

Name: thickness

Class: Thickness

Command-Line Switch: -thickness

Specifies the thickness of the separators in any of the forms ac-

ceptable to Tk_GetPixels. The default is 3 pixels.

Name: width

Class: Width

Command-Line Switch: -width

Specifies the overall width of the paned window in any of the

forms acceptable to Tk_GetPixels. The default is 10 pixels. _________________________________________________________________ zontally. 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 anoth- er.

The iwidgets::panedwindow command creates a new Tcl command whose

name is pathName. This command may be used to invoke various op- erations on the widget. It has the following general form:

pathName option ?arg arg ...?

Option and the args determine the exact behavior of the command.

Many of the widget commands for the panedwindow take as one argu-

ment an indicator of which pane of the paned window to operate on. These indicators are called indexes 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: number Specifies the pane numerically, where 0 corresponds to the nearest (top/left-most) pane of the paned window. end In- dicates the farthest (bottom/right-most) pane of the paned win- dow. pattern If the index doesn't satisfy one of the above forms then this form is used. Pattern 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

Tcl_StringMatch are used.

pathName add tag ?option value option value? Adds a new pane to the paned window on the far side (right/bottom). The following options may be specified: -margin value Specifies the border dis- tance between the pane and pane contents is any of the forms ac- ceptable to Tk_GetPixels. The default is 8 pixels. -minimum value Specifies the minimum size that a pane's contents may reach not inclusive of twice the margin in any of the forms acceptable to Tk_GetPixels. The default is 10 pixels.

The add method returns the path name of the pane. pathName cget

option Returns the current value of the configuration option giv- en by option. Option may have any of the values accepted by the iwidgets::panedwindow command. pathName childsite ?index? Re- turns 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). pathName configure ?option? ?value option value ...? Query or modify the configura- tion options of the widget. If no option is specified, returns a list describing all of the available options for pathName (see

Tk_ConfigureInfo for information on the format of this list). If

option is specified with no value, 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 option is specified). If one or more option-value 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. Option may have any of the values accepted by the iwid*- gets::panedwindow command. pathName delete index Deletes a spec- ified pane given an index. pathName fraction percentage percent- age ?percentage percentage ...? 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. pathName hide index Changes the visiblity of the specified pane, allowing a previously dis- played pane to be visually removed rather than deleted. pathName index index Returns the numerical index corresponding to index. pathName insert index tag ?option value option value ...? Same as the add command except that it inserts the new pane just be- fore the one given by index, instead of appending to the end of the panedwindow. The option, and value arguments have the same interpretation as for the add widget command. pathName panecon*- figure index ?options? This command is similar to the configure command, except that it applies to the options for an individual pane, whereas configure applies to the options for the paned win- dow as a whole. Options may have any of the values accepted by the add widget command. If options are specified, options are modified as indicated in the command and the command returns an empty string. If no options are specified, returns a list de- scribing the current options for entry index (see Tk_ConfigureIn*- fo for information on the format of this list). pathName reset

Redisplays the pane window using default percentages. pathName

show index Changes the visiblity of the specified pane, allowing a previously hidden pane to be displayed.

Dynamic changing of the margin and or minimum options to values

which make the current configuration invalid will block subse- quent 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 com- pressed pane via the paneconfigure method to a large enough val- ue, then sash movement is blocked until the fractions are adjust- ed. This situation is unusual and under normal operation of the panedwindow, this problem will never occur.
