QComboBox as a trigger

[ape]

Ok i guess i do understand the basic idea now a bit better.

My first test does not work, but i guess that has something to do with my implementation.

void MainWindow::showPopup()
{
	// re-Init-Section
	// ....
        // ....
	// end- re-Init Section
 
	QComboBox::showPopup();
}

void MainWindow::showPopup()
{
	// re-Init-Section
	// ....
        // ....
	// end- re-Init Section

	QComboBox::showPopup();
}

To copy to clipboard, switch view to plain text mode 

Error:
mainwindow.cpp:350: error: cannot call member function `virtual void QComboBox::showPopup()' without object

You must subclass QComboBox. You cannot implement its method to another class eg. MainWindow.

class MyComboBox : public QComboBox
{
   ...
};

class MyComboBox : public QComboBox
{
   ...
};
