In my app I use code similar to
NSView *view = [window contentView];
[view lockFocus];
NSBitmapImageRep *bitmap = [[NSBitmapImageRep alloc]
initWithFocusedViewRect:[view bounds]];
[view unlockFocus];
and it works fine on all tested systems (10.2.3, 10.2.8, 10.3.5,
10.3.9,
10.4, 10.4.4(Intel), 10.4.5, 10.4.6).
For the sake of completeness, you can also look at the Carbon sample:
/Developer/Examples/Carbon/Magnify/
Or the source code for OSXvnc on source forge. Both of these use
QuickDraw to capture portions of the screen.
Note QuickDraw is considered deprecated now so I would shy away
from using any method that makes use of QuickDraw.
Anyone know if any of these screenshot methods includes the cursor?
I tested the CG method, but while you can use it to create a live-
updating NSImage containing a screenshot, with sort of "optical
recursion", the cursor is not in the picture.
