Crash after closing by "X" - How to find the bug?

Hello there,

My application compiles, with no warning and any errors.
After executing it makes all i want - all my functions are working fine, so far i can see.

I made an "Exit" QPushButton, and in the "on_exitButton_clicked()"-method just do
"exit(0);" - works totally fine!

But when i push the "X" on top right of the mainwindow, an only then, Windows telling me
"app.exe made an error". This error occurs on two different machines.

If i copy the code out of an example from the QT-assistant and execute it, this error won´t occur!?!

How can i get any Information about what happens while closing by "X"?

I´m working with:
QT 4.4
Eclipse 3.3.2
Qt C++ Eclipse Integration 1.4.0
MinGW-5.1.4.exe
And (sorry for that) on WindowsXP Pro SP2

Thanx a lot in advance.

post ur main.cpp code.

Also better to use the slot quit() in the connect directly instead of exit(0).

My main.cpp? Never changed somthing in it. Was set up automatically:


#include "MainWindow.h"
#include <QApplication>

int main(int argc, char *argv[]) {

QApplication a(argc, argv);

MainWindow w;
w.show();

return a.exec();
}


I deleted some unused Widgets in my UI-File. Since then, the errormessage never appeared again - Happy about it, i won´t ask why.

But Thanx for your help
