Abort Matlab Program via callback

Question

0 个投票

Hello,

I tried to abort my main matlab function via a callback function of an uicontrol function. A short example how I tried to implement it is given below. The problem is that the "error" in the callback only stops the callback function but not the main function. Is there a simple solution to solve this problem? Thanks for your help!

Example code:

function main  
  fh=figure;
  PanicButton=uicontrol('style','pushbutton','Units','normalized',...
      'string','Panic Button','BackgroundColor','r',...
      'FontUnits','normalized','FontSize',.8,...
      'position',[0,0,1,.2],'callback',{@Panic});
   try
      for ct=1:20
          fprintf('%10.6f \n',ct);
          pause(2)
      end
  catch ME
      disp('Hooray! You made it!');
      rethrow(ME)
  end
end
function Panic(hObject,eventdata)
 error('USER:Panic','User has pushed the Panic Button!');
end
