WinOnTop

WINONTOP allows to trigger figure's "Always On Top" feature

Description

WINONTOP allows to trigger figure's "Always On Top" state
INPUT ARGUMENTS:
* FigureHandle - Matlab's figure handle, scalar
* IsOnTop - logical scalar or empty array

USAGE:
* WinOnTop( hfigure, bool );
* WinOnTop( hfigure ); - equal to WinOnTop( hfigure,true);
* WinOnTop(); - equal to WinOnTop( gcf, true);
* WasOnTop = WinOnTop(...); - returns boolean value "if figure WAS on top"
* IsOnTop = WinOnTop(hfigure,[]) - gets "if figure is on top" property

LIMITATIONS:
* java enabled
* figure must be visible
* figure's "WindowStyle" should be "normal"

Thanks, Christine !

Hi Igor,
I'm having trouble getting the code to work. Should the file be placed in the active directory? I also get an undefined function error for 'ishandle_scalar'.

Thanks,
Mark

Hi Igor,
now it works fine. And I want to repeat the sentence I read so often here: Your program is exactly what I needed. Thanks a lot! :)

Hi Christine,
thanks for your notice.
It looks like I've made a couple of mistakes in the original code. I've just uploaded a new version. It would appear in a couple of days.

For now, you may just replace
"ishandle_scalar( FigureHandle )"
with
"isscalar( FigureHandle ) && ishandle( FigureHandle )".

Hello Igor,
I would very like to use your WinOnTop function but I always get an error message because of the ishandle_scalar function that does not seem to exist in my matlab path. Is it possible, that this function does not exist for my version (matlab 7.9 (R2009b)) and was only implemented in a later version? Can I get somehow around using it?

Thanks,
Christine

oops...
Edit:
This version is based on
get(handle(gcf),'JavaFrame') in contrast to
get(gcf,'JavaFrame') ... <blah-blah-blah>

[Igor]

This version is based on get(gcf,'JavaFrame') which won’t return “Warning: figure JavaFrame property will be obsoleted in a future release.”, in contrast to get(gcf,'JavaFrame'), but it’s still possible that it would become obsolete in some future release. Though, most probably, there would be other workaround available.
