Mouse click event problem

[impeteperry]

I am programming using Qt-4.2.3 on a "kubuntu7.04" linux distro.
I have MAJOR problems understanding some of the Qt4 documentation where there is no "code examples" of which there are very few in Qt4.

so

I have a drawing area "frmDrawing" with various items on it. I want to get the position of the mouse when I double click the left mouse button.

Do I use !

globalPos () const : const QPoint &

globalPos () const : const QPoint &

To copy to clipboard, switch view to plain text mode 

if yes, how? or do I use one of the other

QMouseEvent ( Type type, const QPoint & position,
   Qt::MouseButton button, Qt::MouseButtons buttons, Qt::KeyboardModifiers modifiers )

QMouseEvent ( Type type, const QPoint & position,
   Qt::MouseButton button, Qt::MouseButtons buttons, Qt::KeyboardModifiers modifiers )

To copy to clipboard, switch view to plain text mode 

type? again if so what does it look like.?

thanks
