Just add a BOOL to your view subclass that you can set when it needs to
be drawn:
- (void) drawRect: (NSRect) frame
{
if (needsToDraw)
{
needsToDraw = NO;
// Draw
}
}

my app draw a graph in a window. But I find out that the drawRect
method of my customview is called every time that the window becomes
active or inactive. That is, everytime that his status change. (When I
click on another app etc.)
I'm wondering if it's possible that this drawRect method will be
called juste once, at the opening of the window... I don't need more
and it's slowing down my app.
