Look at the g_print, they are equals, only the first word changes..

When I click with the mouse on the drawing area the callback
button_pressed is called and the g_print message shows, and when I
move the window the callback expose_event is called and shows its
g_print. The only difference between both g_print is the first word,
in other words, o parray is correct and the points should be drawned
in the drawing area. But that isn't happening.

Does anyone have an idea about it?

Thanks
