Name: hheeiigghhtt
Class: HHeeiigghhtt
Command-Line Switch: -hheeiigghhtt
Specifies the overall height of the paned window in any of the
forms acceptable to TTkkGGeettPPiixxeellss. The default is 10 pixels.
Name: oorriieenntt

Command-Line Switch: -ssaasshhbboorrddeerrwwiiddtthh
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
TTkkGGeettPPiixxeellss. The default is 2 pixels.
Name: ssaasshhCCuurrssoorr
Class: CCuurrssoorr
Command-Line Switch: -ssaasshhccuurrssoorr
Specifies the type of cursor to be displayed in the sash. The
default is crosshair.

Class: TThhiicckknneessss
Command-Line Switch: -tthhiicckknneessss
Specifies the thickness of the separators in any of the forms
acceptable to TTkkGGeettPPiixxeellss. The default is 3 pixels.
Name: wwiiddtthh
Class: WWiiddtthh
Command-Line Switch: -wwiiddtthh
Specifies the overall width of the paned window in any of the
forms acceptable to TTkkGGeettPPiixxeellss. The default is 10 pixels.
DESCRIPTION
The iiwwiiddggeettss::::ppaanneeddwwiinnddooww command creates a multiple paned window wid-
get 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 posi-
tioning of the panes relative to one another.
MMEETTHHOODDSS
The iiwwiiddggeettss::::ppaanneeddwwiinnddooww 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 ppaanneeddwwiinnddooww take as one argument an
indicator of which pane of the paned window to operate on. These indi-
cators 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.
eenndd 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 TTccllSSttrriinnggMMaattcchh are used.

pathName aadddd tag ?option value option value?
Adds a new pane to the paned window on the far side (right/bot-
tom). The following options may be specified:
-mmaarrggiinn value
Specifies the border distance between the pane and pane
contents is any of the forms acceptable to TTkkGGeettPPiixxeellss.
The default is 8 pixels.
-mmiinniimmuumm 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 TTkkGGeettPPiixxeellss. The default is 10 pix-
els.
The aadddd method returns the path name of the pane.
pathName ccggeett option
Returns the current value of the configuration option given by
option. Option may have any of the values accepted by the iiwwiidd-
ggeettss::::ppaanneeddwwiinnddooww command.
pathName cchhiillddssiittee ?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 ccoonnffiigguurree ?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 avail-
able options for pathName (see TTkkCCoonnffiigguurreeIInnffoo 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 iiwwiiddggeettss::::ppaanneeddwwiinnddooww command.
pathName ddeelleettee index
Deletes a specified pane given an index.
pathName ffrraaccttiioonn 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 hhiiddee index
Changes the visiblity of the specified pane, allowing a previ-
ously displayed pane to be visually removed rather than deleted.
pathName iinnddeexx index
Returns the numerical index corresponding to index.
pathName iinnsseerrtt index tag ?option value option value ...?
Same as the aadddd 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 aadddd widget command.
pathName ppaanneeccoonnffiigguurree index ?options?
This command is similar to the ccoonnffiigguurree command, except that it
applies to the options for an individual pane, whereas ccoonnffiigguurree
applies to the options for the paned window as a whole. Options
may have any of the values accepted by the aadddd 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 TTkkCCoonnffiigguurreeIInnffoo for information on
the format of this list).
pathName rreesseett
Redisplays the pane window using default percentages.
pathName sshhooww index
Changes the visiblity of the specified pane, allowing a previ-
ously hidden pane to be displayed.
NNOOTTEESS
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
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.
