[Qt-interest] Show Open-File-dialog on startup

[Oliver Demetz]

Hi!

My main widget is derived from QWidget

class MainWidget : public QWidget
{
	MainWidget()
	{	
		//bla...inititialisations
		load();
	};

public slots:
	void load(void)
	{
		QString filename = QFileDialog::getOpenFileName(this,
		     tr("Open File"), "", tr("PNGs (*.png)"));
		// and so on...
	};
}

This construction leads to an immediate program abort with message:

Fatal: ASSERT: "!parent ||parent->testAttribute(Qt::WA_WState_Created)" 
in file dialogs\qfiledialog_win.cpp, line 309

Is there a signal being emitted after everything has been created that I 
could connect to the load-slot?

Thanks in advance,
Oliver
