The execution get teminate while accessing variable declared in another class

[sudheer168]

Hi ,I am using QT 4.4.0 .
I here attached a sample code where I got a problem. This application consists of two buttons named "Dialog1" and "Dialog2". If we click on "Dialog1" button, a dialog1 will open which consists of one button and If we click on "Dialog2" button, a dialog2 will open which consists of one button .In dialog2 if click I click the button named "Dialog2_Push" I need to get a pop up a message displaying the variable which I had declared in dialog1.h class. I wrote a piece of code for that but the execution stops when I click a button named "Dialog2_Push" which is on dialog2 class dialog.
So help me or suggest me to access the variable declared in one dialog in another dialog.
Please go through the attached file.

With regards,
Sudheer.
