Tk::tixWm - Tix's addition to the standard TK wm command.

    $widget->wmCapture

    $widget->wmRelease

The wmCapture and the wmRelease methods change the toplevel attribute of Tk widgets.

$widget->wmCapture
Converts the toplevel window specified by $widget into a non-toplevel widget. Normally this command is called to convert a Toplevel widget into a Frame widget. The newly-converted frame widget is un-mapped from the screen. To make it appear inside its parent, you must call a geometry manager (e.g. grid or pack) explicitly.
$widget->wmRelease
Makes the non-toplevel window specified by $widget into a toplevel widget. Normally this command is called to convert a Frame widget into a Toplevel widget, but it can also be used on any non-toplevel widget (e.g, label). The newly-converted toplevel window is in a withdrawn state. To make it appear on the screen, you must call deiconify after calling wmRelease.

Any data associated with $widget via wm methods (icon, protocol, command etc.) are released, and must be re-established if window is later re-captured.

wmCapture does not exist in the Win32 window manager code.

How these methods interact with perl/Tk's class hierarchy is not yet clear. In particular a wmReleased window will not automatically ``inherit'' the Tk::Wm methods, however a wmCaptured window still will. (A released Label might make a good candidate for an Icon.)
