Re: No matching function for call to Gdk::Window::invalidate_rect(int, bool)

[Christopher Harvey <chris basementcode com>]

Hi Francois,
try passing in a rectangle instead of a number. If you were passing in 0 
as in "NULL" that function doesn't take pointers, it takes a reference 
to a rectangle, that means you need to use an actual rectangle object 
and not a pointer to one or anything else.

doing

Rectangle myRect;

drawing_area->get_window()->invalidate_rect(myRect, false) ;


would work for example.
