Hi,
A couple of months ago, I posted about an apparently
benign error my app was generating on the console:
CGContextSetStyle: invalid context
(The original thread can be found here:
http://www.cocoabuilder.com/archive/message/cocoa/2007/8/24/188258)
It has had me stumped ever since, but today I *think*
I have finally found the cause. (The strange thing was
that this error only ever appeared if projects were
opened via File > Open; my app automatically opens the
last project when it is launched, and the error never
seems to occur in this circumstance so I kept missing
it - weird.)
It seems to come from the fact that I add a shadow to
the text of my NSOutlineView source list using
-outlineView:willDisplayCell:forTableColumn:item: as
follows:
- (void)outlineView:(NSOutlineView *)olv
willDisplayCell:(id)cell
forTableColumn:(NSTableColumn *)tableColumn
item:(id)item
{
NSShadow *shadow = [[NSShadow alloc] init];
[shadow setShadowOffset:NSMakeSize(0, -1.1)];
[shadow setShadowColor:[NSColor grayColor]];
[shadow set];
[shadow autorelease];
}
The above code seems to cause a "CGContextSetStyle:
invalid context" console error whenever it is called
if the item is selected (which, unfortunately, is the
exact case in which I want to add a shadow in my code
- for selected items).
Can anyone see what I am doing wrong here, or why this
might be generating such an error? Is there a better
way of setting the shadow that will avoid this console
error?
Many thanks in advance,
Keith
