Pixels. 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.

valid options are 0 and 1.

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 manipu-lation manipulation
lation 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 informa-tion information
tion 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 correspond-ing corresponding
ing 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 val-ues values
ues 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 visu-ally visually
ally 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 speci-fied, specified,
fied, 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 dis-played. displayed.
played.
NOTES
Dynamic changing of the margin and or minimum options to values which make the current config-uration configuration
uration 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 frac-tions fractions
tions 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
