GTK_MOTION_NOTIFY over pango layout.

["Philippe A" <z77y16 hotmail com>]

Hello everyone,

The Bluefish editor has an option to display line numbering or not. Line 
numbering is drawn with pango layout.  According the the comments, gedit 
does the same thing. I am writing a patch so that lines get selected when 
clicking+dragging over line numbers.

I've come into a strange problem. I receive much less motion signals when my 
cursor is over the pango layout than when the cursor is over the text view. 
When I'm over the layout, I basically receive two motion signals : one when 
I start dragging and one when I release my mouse button after dragging. 
Doing the same over text will produce motion signals whenever the mouse 
moves.

Do you have any idea why the signals aren't emitted the same way? Because of 
this problem, the selection I am creating when selecting line numbers only 
appears when I release the mouse button.

Thanks for any insights!
