QDockWidget move problem when using custom title widget

[alexi_nedo]

Thank you very much for your answer. Can you explain how can I call

QMouseEvent::ignore()

QMouseEvent::ignore()

To copy to clipboard, switch view to plain text mode 

by giving a piece of code.
I tried the following but the mouseMoveEvent never reaches to parent widget so I can not move the widget.

void MyDockTitle::mouseMoveEvent ( QMouseEvent * event ) 
{
	qDebug()<< "mouseMoveEvent";
	event->ignore();
}

void MyDockTitle::mouseMoveEvent ( QMouseEvent * event ) 
{
	qDebug()<< "mouseMoveEvent";
	event->ignore();
}

To copy to clipboard, switch view to plain text mode 

Thanks in advance...
