Getting the correct position of mouseclicks from a pixmap?

[Erik Mouw <J A K Mouw its tudelft nl>]

Hi,

I want to get the position of mouseclicks from a GtkPixmap, so I put it in
a GtkEventBox to get the button_press_event. To allow that the size of the
pixmap is bigger than the toplevel window, I put the GtkEventBox in a
GtkScrolledWindow.

If I click the pixmap, I actually get the position of the clicks relative
to the GtkEventBox. How do I get the position relative to the GtkPixmap?
