toggle button to stop a for loop not working
显示 更早的评论
I am trying to exit a for loop using toggle button, created using guide. Toggle button is initially called 'Run'. The iteration starts when 'Run' is hit and the toggle button string changes to 'Stop'. However, iteration continues after 'Stop' is hit (in the screenshot, 'Stop' is hit at i=2). I used dbstack to check the Run callbacks. Am I missing something obvious?? Any help would be appreciated. Here's the code snippet and the command window screenshot-

I don't have time to debug your code tonight, but you can try my demo of basically the same thing. attached.

Thank you very much Image Analyst.
Thank you Geoff Hayes (concerning another post mentioned below)
The part I was missing was to check the value of the hObject inside the for loop. This is due to the fact that multiple calls to callback function are stacked and executed subsequently (nicely explained here - https://in.mathworks.com/matlabcentral/answers/162797-how-to-continue-from-same-line-using-toggle-button-gui ). As I did not check the updated property of hObject inside the for loop, after the second callback to the toggle button finished, the first callback continued without reflecting the updated hObject value. Here's the modified code snippet -
