WindowKeyPressFcn executes after program interruption
I want to detect pressing of the key, when running matlab script in while loop. At the moment, I only want to display success, after pressing of the key. Unfortunately, the message is displayed only after program interruption (CTRL+C) not during program run. Here is the code:
% Init of callback
fig = gcf;
set(fig,'WindowKeyPressFcn',@keyPressCallback);
% keyPressCallback function
function keyPressCallback(source,eventdata)
keyPressed = eventdata.Key;
if strcmpi(keyPressed,'space')
disp('success');
end
end
matlab callback

You need to break the cycle of the script which is running so that Matlab will process other events, in essense your keypress. You can do that by adding a drawnow inside you while loop, the code below should give you enough to incorporate in your own:
fig = figure;
set(fig,'WindowKeyPressFcn',@(hFig,hEvent)fprintf('pressed key %sn',hFig.CurrentKey) );
drawnow();
while true
if ~ishandle(fig); break; end
drawnow();
end
