Ok,ok.. now i see the difference.. GdkEventMotion doesn't have the
button field included in GdkEventButton structure. I didn't notice
this..

Then... in GdkEventButton, if the state field already has information
about the button pressed, why does it also include a button field? For
an easier use?
I mean "if (event->button = 1)" is the same as "if (event->state &
GDK_BUTTON1_MASK)", right?

Thanks again,
