[Kde-bindings] Qt, Qyoto buttons work intermediately

[linuxoidoz at yahoo.com.au]

I'm completely lost. No controls work in the second window. Sometimes 1 out 20, the buttons work but then stop again. What the... I have these:

mainwin = new QMainWindow(MainWindow);

...

		QObject.Connect(txtSource, Qt.SIGNAL("textChanged()"), mainwin, Qt.SLOT("updateFilename()"));
		QObject.Connect(btnSource, Qt.SIGNAL("clicked()"), mainwin, Qt.SLOT("GetSource()"));
		QObject.Connect(btnDestination, Qt.SIGNAL("clicked()"), mainwin, Qt.SLOT("GetDestination()"));
		QObject.Connect(btnStart, Qt.SIGNAL("clicked()"), mainwin, Qt.SLOT("StartCodec()"));
		QObject.Connect(btnQuit, Qt.SIGNAL("clicked()"), Qt.qApp, Qt.SLOT("quit()"));
		QMetaObject.ConnectSlotsByName(mainwin);
	}
	
	[Q_SLOT]
	private void updateFilename() {
		txtFilename.Text = txtSource.Text;
		btnStart.SetEnabled(true);	
	}
	
	[Q_SLOT]
	private void GetSource() {
		string fileName = QFileDialog.GetOpenFileName();
		txtSource.Text = fileName;
	}
	
	[Q_SLOT]
	private void GetDestination() {
		string fileName = QFileDialog.GetOpenFileName();
		txtDestination.Text = fileName;
	}
	
	[Q_SLOT]
	private void StartCodec() {
		string param = "kwrite " + txtSource.Text;
		QProcess play = new QProcess(mainwin);
		play.Start(param);
	}


I've just tried putting everything on the first window and all controls work just fine. But none work on the second window which I open from the first and pass its parent reference to.

Could it be something wrong with my class constructors/references?

Will really appreciate your help.

> Don't know if this is a Qyoto bug or I'm doing something wrong. When I build my project and click buttons sometimes they work, sometimes they don't. If I rebuild it, then they might start working or stop. Really strange.
