get Parent Pointer

[raphaelf]

Hello everybody,

QT:4.1.1

How could i get my parent Pointer?

I tryed this:
login.cpp

(MainWindow*)parent).insertTables();

(MainWindow*)parent).insertTables();

To copy to clipboard, switch view to plain text mode 

ERROR:

login.cpp:63: error: argument of type `QObject*(QObject::)() const' does not mat
ch `MainWindow*'

login.cpp:63: error: argument of type `QObject*(QObject::)() const' does not mat
ch `MainWindow*'

To copy to clipboard, switch view to plain text mode 

I want to get the pointer to call a function of MainWindow. I open LoginDialog like this:

void MainWindow::openLoginDialog()
{
	LoginDialog l(this);
    l.exec();
 
}

void MainWindow::openLoginDialog()
{
	LoginDialog l(this);
    l.exec();

}

To copy to clipboard, switch view to plain text mode 

Have somebody a idea how to get the Parent Pointer?
