DESCRIPTIONThe wmCapture and the wmRelease methods change the toplevel attribute of Tk widgets.
- 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.
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is in a withdrawn state.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.
BUGSwmCapture 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.)
