MATLAB ResizeFcn callback fails

I am editing a GUI written in MATLAB and have a line in the OpeningFcn that sets the callback for resizeing the figure.

set(hObject, 'UserData', handles.ParentFig, 'ResizeFcn',@cbFigResize, 'CloseRequestFcn', @Cancel);

The callback is pasted below with much edited out for simplicity.

function cbFigResize(src,evt) 
  % check if figure width is less than 600 
  if fpos(3) < 600  
    %set min. width to 600 
    fpos(3) = 600 
  end 
  %check if figure height is less than 560 
  if fpos(4) <560 
    % set minimum height to 560 
    fpos(4) = 560; 
  end

My coworker runs Windows XP and an earlier version of MATLAB. I run Windows 7 and MATLAB 7.12.0.635. Now when he resizes figures they always resize properly. When I run the same code I can sometimes get the figure smaller than the above set minimum width and height limits. My coworker says it is a Windows 7 interrupt problem. If anybody else out there has this problem he found a simple but illogical workaround which I will post below.

function cbFigResize(src,evt,doStop) 
if nargin < 3 
    doStop = false; 
end 

% check if figure width is less than 600 
if fpos(3) < 600  
    %set min. width to 600 
    fpos(3) = 600 
end 
%check if figure height is less than 560 
if fpos(4) <560 
    % set minimum height to 560 
    fpos(4) = 560; 
end 

if ~doStop 
    cbFigResize(src,evt,true) 
end

You can see that this function calls itself with a flag that stops if from becoming an infinite loop. And now I cannot resize windows below the minimum. Has anybody any insights into this behavior?

This is not a valid definition of the ResizeFcn:

'ResizeFcn',@ResizeFcn',@cbFigResize,   ?!

You can use this to limit the figure size:

jFrame = get(handle(gcf), 'JavaFrame');
try
  jProx = jFrame.fFigureClient.getWindow();
catch
  jProx = jFrame.fHG1Client.getWindow(); 
end
jProx.setMinimumSize(java.awt.Dimension(600, 560));

Oops, that was a typo.

Bravo! That works!

Thanks!

I received this error message..

No appropriate method, property, or field fFigureClient for class

com.mathworks.hg.peer.HG1FigurePeer.

and I found following script..

jFrame = get(handle(gcf), 'JavaFrame');

jProx = jFrame.fHG1Client.getWindow();

jProx.setMinimumSize(java.awt.Dimension(600, 560));

@Kyungjoon: Please post your Matlab and Java version.
