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"

Works well and well documented. Thanks Igor

Nice !
Exactly what I was looking for, this is great.

@Alexander B. ,
No, AFAIU.
Alexander B. (view profile)
is there a way to specify a process so that the figure is only on top of that process and not other windows?

nice

This function is not working, I got this error on line 92 :
Struct contents reference from a non-struct array object.

Jerry,
Thanks for the notice! I've just uploaded the fixed version.
Jerry (view profile)
bug in line 61, should be if ~exist('isOnTop','var'); isOnTop=true; end
otherwise, the On Top Status could not be switched to 'Off'

I use it every day!

PERFECT! Works from the box

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.
Sebastian (view profile)
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".

Great!!!

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...
Michael Hubatka (view profile)
using
javax.swing.SwingUtilities.getWindowAncestor(jFrame.getAxisComponent);
instead of
jFrame.fHG2Client
worked for me.
Alessandro Russo (view profile)
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 want to use this file while in opening function of GUI, But i am getting error that Figure is not visible. I can i make the GUI on top using opening function

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

How can I find that file?
Igor (view profile)
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! :)
Igor (view profile)
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 )".
Christine (view profile)
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 (view profile)
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.
