How to give focus to GUI windows?

Hi all,

In my application I have a routine that takes some time to calculate
things, then makes a graph using 'figure' and so on in order to save
this using 'print', and then shows a messagebox that it's ready. If,
during calculations, the user pops up another Windows application that
covers my Matlab application on the screen, I see that:

  * The Matlab graphs do not get on top of the screen, and that for that
reason the print statement does not save the contents of the graph to my
disk, but the contents of the other Windows application on the place
where the graph is supposed to be!
  * The messagebox stays underwater, covered by the other Windows
application and the user doesn't know that it's there...

Things like:

* figure(fig_handle)
* figure(msgbox_handle)
* drawnow

do not seem to get the figures or msgbox on top of the screen. Does
anybody have a solution for this?

Thanx,

   Jeroen

Try the following hack:
jf=get(get(fig_handle,'JavaFrame'),'FigurePanelContainer');
jf.getComponent(0).getRootPane.getTopLevelAncestor.setAlwaysOnTop(1);

Note: this relies on undocumented & unsupported Matlab
functionality

It works! But you already knew that... Thanx :-)
