SYNOPSIS
iwidgets::panedwindow pathName ?options?
INHERITANCE
itk::Widget <- iwidgets::Panedwindow
STANDARD OPTIONS
background cursor
See the "options" manual entry for details on the standard options.
WIDGET-SPECIFIC OPTIONS
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 horizontal. 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 acceptable 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.

DESCRIPTION
The iwidgets::panedwindow 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.
METHODS
The iwidgets::panedwindow command creates a new Tcl command whose name is pathName. This
command may be used to invoke various operations 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 argument 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 Indicates the farthest (bottom/right-most) pane of the paned window.
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.
WIDGET-SPECIFIC METHODS
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 distance between the pane and pane contents is any of
the forms acceptable 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 given by option. Option may
have any of the values accepted by the iwidgets::panedwindow command.
pathName childsite ?index?
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).
pathName configure ?option? ?value option value ...?
Query or modify the configuration 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 iwidgets::panedwindow command.
pathName delete index
Deletes a specified pane given an index.
pathName fraction percentage percentage ?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 displayed 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 before 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 paneconfigure 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 window 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 describing the current options for entry index (see Tk_ConfigureInfo
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.
NOTES
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.
EXAMPLE
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
