| Name | Database name | Database class |
|---|
| -handlepad | handlePad | HandlePad |
| | When sash handles are drawn, specifies the distance from the top or
left end of the sash (depending on the orientation of the widget) at
which to draw the handle. May be any value accepted by Tk_GetPixels.

The panedwindow command creates a new window (given by the
pathName argument) and makes it into a panedwindow widget.
Additional options, described above, may be specified on the command
line or in the option database to configure aspects of the panedwindow
such as its default background color and relief. The
panedwindow command returns the path name of the new window.
A panedwindow widget contains any number of panes, arranged
horizontally or vertically, according to the value of the
-orient option. Each pane contains one widget, and each pair of
panes is separated by a moveable (via mouse movements) sash. Moving a
sash causes the widgets on either side of the sash to be resized.
The panedwindow command creates a new Tcl command whose name is
the same as the path name of the panedwindow's window. This command
may be used to invoke various operations on the widget. It has the
following general form:
pathName option ?arg arg ...?
PathName is the name of the command, which is the same as
the panedwindow widget's path name. Option and the args
determine the exact behavior of the command. The following
commands are possible for panedwindow widgets:
- pathName add window ?window ...? ?option value ...?
- Add one or more windows to the panedwindow, each in a separate pane.
The arguments consist of the names of one or more windows
followed by pairs of arguments that specify how to manage the windows.
Option may have any of the values accepted by the
configure subcommand.
- pathName cget option
- Returns the current value of the configuration option given by
option. Option may have any of the values accepted by the
panedwindow command.
- 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 panedwindow command.
- pathName forget window ?window ...?
- Remove the pane containing window from the panedwindow. All
geometry management options for window will be forgotten.
- pathName identify x y
- Identify the panedwindow component underneath the point given by
x and y, in window coordinates. If the point is over a
sash or a sash handle, the result is a two element list containing the
index of the sash or handle, and a word indicating whether it is over
a sash or a handle, such as {0 sash} or {2 handle}. If the point is
over any other part of the panedwindow, the result is an empty list.
- pathName proxy ?args?
- This command is used to query and change the position of the sash
proxy, used for rubberband-style pane resizing. It can take any of
the following forms:
- pathName proxy coord
- Return a list containing the x and y coordinates of the most recent
proxy location.
- pathName proxy forget
- Remove the proxy from the display.
- pathName proxy place x y
- Place the proxy at the given x and y coordinates.
- pathName sash ?args?
- This command is used to query and change the position of sashes in the
panedwindow. It can take any of the following forms:
- pathName sash coord index
- Return the current x and y coordinate pair for the sash given by
index. Index must be an integer between 0 and 1 less than
the number of panes in the panedwindow. The coordinates given are
those of the top left corner of the region containing the sash.
- pathName sash dragto index x y
- This command computes the difference between the given coordinates and the
coordinates given to the last sash mark command for the given
sash. It then moves that sash the computed difference. The return
value is the empty string.
- pathName sash mark index x y
- Records x and y for the sash given by index; used in
conjunction with later sash dragto commands to move the sash.
- pathName sash place index x y
- Place the sash given by index at the given coordinates.
- pathName panecget window option
- Query a management option for window. Option may be any
value allowed by the paneconfigure subcommand.
- pathName paneconfigure window ?option? ?value option value ...?
- Query or modify the management options for window. 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. The following options
are supported:
- -after window
- Insert the window after the window specified. window should be the
name of a window already managed by pathName.
- -before window
- Insert the window before the window specified. window should be
the name of a window already managed by pathName.
- -height size
- Specify a height for the window. The height will be the outer
dimension of the window including its border, if any. If size
is an empty string, or if -height is not specified, then the
height requested internally by the window will be used initially; the
height may later be adjusted by the movement of sashes in the
panedwindow. Size may be any value accepted by Tk_GetPixels.
- -hide boolean
- Controls the visibility of a pane. When the boolean is true
(according to Tcl_GetBoolean) the pane will not be visible, but
it will still be maintained in the list of panes.
- -minsize n
- Specifies that the size of the window cannot be made less than
n. This constraint only affects the size of the widget in the
paned dimension -- the x dimension for horizontal panedwindows, the y
dimension for vertical panedwindows. May be any value accepted by
Tk_GetPixels.
- -padx n
- Specifies a non-negative value indicating how much extra space to
leave on each side of the window in the X-direction. The value may
have any of the forms accepted by Tk_GetPixels.
- -pady n
- Specifies a non-negative value indicating how much extra space to
leave on each side of the window in the Y-direction. The value may
have any of the forms accepted by Tk_GetPixels.
- -sticky style
- If a window's pane is larger than the requested dimensions of the
window, this option may be used to position (or stretch) the window
within its pane. Style is a string that contains zero or more
of the characters n, s, e or w. The string
can optionally contains spaces or commas, but they are ignored. Each
letter refers to a side (north, south, east, or west) that the window
will
"stick" to. If both n and s (or e and w)
are specified, the window will be stretched to fill the entire height
(or width) of its cavity.
- -stretch when
- Controls how extra space is allocated to each of the panes.
When is one of always, first, last,
middle, and never.
The panedwindow will calculate the required size of all its panes. Any
remaining (or deficit) space will be distributed to those panes marked
for stretching. The space will be distributed based on each panes
current ratio of the whole. The when values have the following
definition:
- always
- This pane will always stretch.
- first
- Only if this pane is the first pane (left-most or top-most) will it
stretch.
- last
- Only if this pane is the last pane (right-most or bottom-most) will it
stretch. This is the default value.
- middle
- Only if this pane is not the first or last pane will it stretch.
- never
- This pane will never stretch.
- -width size
- Specify a width for the window. The width will be the outer
dimension of the window including its border, if any. If size
is an empty string, or if -width is not specified, then the
width requested internally by the window will be used initially; the
width may later be adjusted by the movement of sashes in the
panedwindow. Size may be any value accepted by Tk_GetPixels.
- pathName panes
- Returns an ordered list of the widgets managed by pathName.
A pane is resized by grabbing the sash (or sash handle if present) and
dragging with the mouse. This is accomplished via mouse motion
bindings on the widget. When a sash is moved, the sizes of the panes
on each side of the sash, and thus the widgets in those panes, are
adjusted.
When a pane is resized from outside (e.g. it is packed to expand and
fill, and the containing toplevel is resized), space is added to the final
(rightmost or bottommost) pane in the window.
