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;

waitfor(h)
disp(clock)

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.
