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.
