DESCRIPTION
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 horizon-
tally 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.
WIDGET COMMAND
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 panedwin-
dow widget's path name. Option and the args determine the exact behav-
ior of the command. The following commands are possible for panedwin-
dow 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 con-
figure 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 avail-
able 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 con-
junction 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 path-
Name.
-before window
Insert the window before the window specified. window
should be the name of a window already managed by path-
Name.
-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.
-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 hor-
izontal panedwindows, the y dimension for vertical paned-
windows. 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-direc-
tion. 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-direc-
tion. The value may have any of the forms accepted by
Tk_GetPixels.
-sticky style
If a window's pane is larger than the requested dimen-
sions 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.
-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.
RESIZING PANES
A pane is resized by grabbing the sash (or sash handle if present) and
dragging with the mouse. This is accomplished via mouse motion bind-
ings 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.
