Dear my friends...
I am using QT Designer from SuSE 9.1 to create a
database application.
I made it to load a child (QDialog, custbaruForm) form
into a parent form (MDI Window, depanForm).
But after the child form displayed, the parent window
is frozen. I can not do anything on the application. I
close the application with xkill.
Could anybody so nice to tell the solution?

int main( int argc, char ** argv )
{
QApplication a( argc, argv );
depanForm w;
a.setMainWidget(&w);
w.showMaximized();
a.connect( &a, SIGNAL( lastWindowClosed() ), &a,
SLOT( quit() ) );
return a.exec();
}
