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.
Specifies a desired height for the overall panedwindow widget.
May be any value accepted by Tk_GetPixels. If an empty string,
the widget will be made high enough to allow all contained widgets
to have their natural height.
Mouse cursor to use when over a sash. If null,
sb_h_double_arrow will be used for horizontal panedwindows,
and sb_v_double_arrow will be used for vertical
panedwindows.
Specifies a desired width for the overall panedwindow widget.
May be any value accepted by Tk_GetPixels. If an empty string,
the widget will be made wide enough to allow all contained widgets
to have their natural width.
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:
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.
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.
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.
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:
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.
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.
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:
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.
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.
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.
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.
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.
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.
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:
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.
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.
