Problem with QDialog class

[sudheer168]

Hi ,I am using Qt 4.4.0 .In my application I want to access the members/variables of one dialog class in another dialog class.Now I am able to access the variables/members of Mainwindow class in any other dialog.The code i used to access is shown below

MainWindow *omans = qobject_cast<MainWindow *>(parentWidget());
omans->natimer->stop();

MainWindow *omans = qobject_cast<MainWindow *>(parentWidget());
omans->natimer->stop();

To copy to clipboard, switch view to plain text mode 

I wrote the above code in other dialog class to access the "natimer " which i was declared in mainwindow.
Now I want to access the member of one dialog class in another dialog class.
I tried the same code to access the member of one dialog class in another dialog class,but the execution get breaks .
So help me to solve the problem.

With Regards,
Sudheer.

You have to cast the window to the type of your class (not just to a QMainWindow).
A QMainWindow does not exhibit that timer.
(You might also prefer not to access internals of your class like that. How about adding a slot "stopTimer()" to your class?)

@Caduel, his class is MainWindow, not QMainWindow.

Can u show that relevant code ?

[caduel]

right you are

(The error might be that (due to a missing Q_OBJECT in the class decl of MainWindow) the qobject_cast returns NULL.)
