Tk::StayOnTop 0.12

Tk::StayOnTop can keep your window in the foreground.

SYNOPSIS

use Tk::StayOnTop;
$toplevel->stayOnTop;
$toplevel->dontStayOnTop;

Adds methods to the Tk::Toplevel base class so that a window can stay on top off all other windows.

METHODS

$toplevel->stayOnTop();

Keep $toplevel in the foreground.

$toplevel->dontStayOnTop();

Return $toplevel to normal behaviour.

IMPLEMENTATION DETAILS

The module uses a number of methods for trying to keep the window in the foreground. It will atomatically choose the most suitable available. The methods can be split between Microsoft Windows and X-Windows:

Microsoft Windows

Perl Tk Version 804.027 and newer support the "-toplevel => 1" attribute. This will be used if possible.

On older Perl Tk versions, the module will search for the Win32::API module and use direct API calls to the OS.

X-Windows

For newer X window managers (Gnome, myabe KDE) it will try to set the NET_WM_STATE_STAYS_ON_TOP property of the window.

If this is not implemented, it will just try to the raise window every time it's covered. This could cause problems if you have two windows competing to stay on top.

I am hoping that the Perl Tk build in "-toplevel => 1" attribute will be implement in the future and this module will no longer be needed. However in the mean time, if you have any other platform dependent solutions, please let me know and I will try to include them.
