Click coordinates

   Hi,

I display a BMP  in a GtkImage itself in a GtkEventBox to get mouse click.

When I click in the BMP, I want to:

1°) know the color of the clicked pixel
2°) display something around there

For this purpose, I get a GdkPixbuf from GtkImage 

If the window is the size of BMP, everything is OK.

On the other way, if the window is bigger than the BMP (there's a gray part on 
the left), the coord I get for the mouse click from GdkEventButton.x and 
GdkEventButton.y has an offset corresponding to the width of the gray part.

How can I known the offset between the GtkEventBox (or the GtkImage) and the 
GdkPixbuf ?

   Thanks,


   Matthieu
