GUI closing automatically?

Asked by Niranjan

Hi I've got a problem again. I've got a face detection algorithm. When I try to implement in GUI. After selecting the first button, the corresponding operation takes place but this closes the GUI! Where should the problem probably be? Any guesses? And how can I avoid this??

I would assume you have a close, closereq, or delete somewhere in your code. Put a breakpoint on the first line of your button callback, and step through one line at a time, and you should be able to discover the problem

I am sorry guys , Jiro was rite . It is my habit to use clc;clear all;close all; at the starting of the code. That's what caused me the problem. When I removed it ,things were back to normal.

Another strong hint that "clc;clear all; close all" is not useful but more likely causes trouble.
