LOST MOTION NOTIFY EVENT

[Toni Moreno Giménez <toni moreno gimenez wanadoo es>]

Hi, I have a little problem when controling a "special" control using the 
motion notify event, this event must change a internal value when mouse 
button is pressed , the problem comes when the pointer leaves the widget and 
no more motion notify events are handled , how can I reveive motion notify 
events , even when pointer leaves the widget that handles this special 
control?

I have noticed  the Gtk{H,V}Scrollbar (GtkRange) can handle movement even 
when pointer leaves the widget and window  application, I have seen the code 
but I can undestand yet how to do it.


Lots of thakns.
