MATLAB中的Java Robot和KeyEvent

Question

I have a question regarding using robot and keyevent in MATLAB

import java.awt.Robot;
import java.awt.event.KeyEvent;
robot = Robot;
if isequal(eventdata.Key,'return')  % capture enter 
  robot.keyPress(KeyEvent.VK_ENTER);
  robot.delay(0.1);
  robot.keyRelease(KeyEvent.VK_ENTER);
end

This block of code performs its function correctly. However, it create an enter event outside from the form itself. How do I contain it in the active form or gui only not in other documentation ?

Answer 1

I had a similar problem and was able to solve it by setting focus to the desired figure in addition with some "waiting":

figure(myfigureHandle) %set focus to myFigure
pause(1) %wait for a short amount of time
import java.awt.Robot; import java.awt.event.*; SimKey=Robot;... %doing the robot stuff

In your case, the pause-command should only be used, when you are within the if-condition.

Hope that helps!
