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

| Watch this File

File Information
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"
Written by Igor
i3v@mail.ru
2013.06.16 - Initial version
2013.06.27 - removed custom "ishandle_scalar" function call
2015.04.17 - adapted for changes in matlab graphics system (since R2014b)
2016.05.21 - another ishg2() checking mechanism

Sebastian,
thanks for the notice, I never ran into such versions myself. I've just uploaded a version, with a completely different approach to the handle graphics version check.

You should be careful with this test: "if str2double(v.Version) >= 8.4" Because some Matlab versions have two dots in its version, like R2010bSP2 uses "7.11.2".

I've just updated the submission, so now it should work in either case: >=R2014b and <=R2014a , without any modification.
I'm sorry for not doing this for so long..

Michael Hubatka,
Alessandro Russo,
Many thanks for your suggestions!
It looks like Mathworks is going to add more modifications to their graphics system... So, it looks like it is hard to predict, which functionality would be removed in the following versions and which would not...

using
javax.swing.SwingUtilities.getWindowAncestor(jFrame.getAxisComponent);

instead of
jFrame.fHG2Client

worked for me.

I found the solution myself... just change HG1 to HG2 at line 68 and 71.

Ale

ps: HG stands for Handle Graphics and matlab switched from version 1 to version 2 in R2014b (see for instance http://undocumentedmatlab.com/blog/customizing-axes-rulers).

Hi Igor,

in R2014b WinOnTop doesn't work anymore. I get the following error:

>> WinOnTop
Warning: figure JavaFrame property will be obsoleted in a future release. For more information see the JavaFrame resource on the MathWorks web site.
> In WinOnTop at 64
No appropriate method, property, or field fHG1Client for class com.mathworks.hg.peer.HG2FigurePeer.

Error in WinOnTop (line 68)
WasOnTop = jFrame.fHG1Client.getWindow.isAlwaysOnTop;

Can you fix it? :-)

Ciao
Ale

I was trying to put an overlay window on top of X-Plane with no success - until I used your code! MANY THANKS.

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>

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.
