Pause until a figure close OR a button is pressed

Hi.

In the middle of my script I ask the user to zoom a figure and call ginput afterwards. I would like to interrupt (return) the script if the user closes the figure. Right now I did

h=figure;
plot(1:1000,randn(1000,1))
zoom on
pause
if ~isvalid(h),return,end
try 
  [x,y]=ginput(1)
end

However this waits for the user to click a button even if the figure is closed. That is, the user closes the figure, but the script does not notice it until it ALSO press a button. The uiwait or waitfor command could understand if the figure is closed, but then I have to close the figure in order to make the script continue.

Is it possible to obtain a result similar to

figure
zoom on
event=pauseOrWaitfor
if event=='figureClosed'
  return
elseif event=='userClickedAButton'
  %Do other things here
end

thank you

h = figure;
drawnow;
disp(clock)
waitfor(h)
disp(clock)

Sorry Jan, but doesn't this require h to be closed to continue?

As I said in the question: "The uiwait or waitfor command could understand if the figure is closed, but then I have to close the figure in order to make the script continue"

Am I wrong?

I'm looking for a solution that continue either if the figure is close or if the user push a button, and maybe recognize which of the two happened.

If both options are needed you could use waitforbuttonpress to detect if the user presses a key or clicks a mouse button and catch closing of the figure in a try/catch statement:

h = figure;
drawnow;
disp(clock)
try
    waitforbuttonpress
    % Close figure or leave it open
    close(h)
    disp('mouse or key pressed')
catch
    disp('figure closed')
end
disp(clock)

Note that focus on the current figure is required (from R2014 on) to resume program execution after mouse or button presses.
