DESCRIPTION
The Panedwindow method creates a new window (given by the $panedwindow
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.
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.
WIDGET METHODS
The Panedwindow method may be used to invoke various operations on the
widget. It has the following general form:
$widget->method(?arg arg ...?);
The following commands are possible for Panedwindow widgets:
$widget->add(?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.
$widget->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.
$widget->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 $widget (see Tk::configure 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.
$widget->forget(?window ...?);
Remove the pane containing $widget from the Panedwindow. All
geometry management options for $widget will be forgotten.
$widget->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.
$widget->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:
$widget->proxyCoord;
Return a list containing the x and y coordinates of the most
recent proxy location.
$widget->proxyForget;
Remove the proxy from the display.
$widget->proxyPlace(x, y);
Place the proxy at the given x and y coordinates.
$widget->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:
$widget->sashCoord(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.
$widget->sashDragto(index, x, y) This command computes the
difference between the given coordinates and the coordinates
given to the last sash coord command for the given sash. It
then moves that sash the computed difference. The return value
is the empty string.
$widget->sashMark(index, x, y);
Records x and y for the sash given by index; used in conjunction
with later dragto commands to move the sash.
$widget->sashPlace(index, x, y);
Place the sash given by index at the given coordinates.
$widget $widget->panecget(option);
Query a management option for $widget. Option may be any value
allowed by the paneconfigure subcommand.
$widget $widget->paneconfigure(?option? ?value option value ...?);
Query or modify the management options for $widget. If no option is
specified, returns a list describing all of the available options
for $widget (see Tk::configure 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 => $widget
Insert the window after the window specified. $widget should be
the name of a window already managed by $widget.
-before => $widget
Insert the window before the window specified. $widget should
be the name of a window already managed by $widget.
-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 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.
-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.
$widget->panes;
Returns an ordered list of the widgets managed by $widget.
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 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 (eg, 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.
