Hi list,

I am trying to use a GMisc.drawing_area widget within a GBin.event_box
and there's two things that I can't do in a simple way.

1) The first thing is have a simple freeze / thaw on the widget to use
double buffering. I tried several things to freeze :
first #misc#set_double_buffered true
then before modifications,
  - #misc#set_app_paintable false ;
  - #misc#freeze_notify () ;
  - #misc#hide () ;
and respectively after the modifications,
  - #misc#set_app_paintable true
  - #misc#thaw_notify () ;
  - #misc#show ()
None of these work. I noticed in the timer.ml example that a new
pixmap is used each time and all operations are drawn in this pixmap.
I tried this, which works, but is slower. Is this the only way to go?

2) The second thing is to track the mouse moves over the widget but
without any click... (ebox#event#connect#motion_notify seems to call
back only when mouse button is pressed). Which event did I miss?

Thank you by advance for your answers and go lablgtk (and lablgl!).

Henri
