Ok I know I must be missing something dumb.
i'm trying to draw borders for the window,
- (void) awakeFromNib{
[window setStyleMask:NSBorderlessWindowMask];
[window setOpaque:YES];
NSDrawNinePartImage([[window contentView]frame],
nil,
nil,
nil,
[NSImage imageNamed:@"right3.png"],
nil,
[NSImage imageNamed:@"left3.png"],
[NSImage imageNamed:@"right4.png"],
[NSImage imageNamed:@"left5.png"],
[NSImage imageNamed:@"left4.png"],
NSCompositeClear,
1.0,
NO);
but i get an error on runtime.
<Error>: CGContextGetStyle: invalid context 0x0
It does not make sense to draw an image when [NSGraphicsContext currentContext] is nil. This is a programming error.
Break on _NSWarnForDrawingImageWithNoCurrentContext to debug. This will be logged only once. This may break in the future.
CGContextClipToRect: invalid context 0x0
<Error>: CGContextSetAlpha: invalid context 0x0
<Error>: CGContextGetUserSpaceToDeviceSpaceTransform: invalid context 0x0
<Error>: CGContextDrawTiledImage: invalid context 0x0
<Error>: CGContextClipToRect: invalid context 0x0
<Error>: CGContextSetAlpha: invalid context 0x0
<Error>: CGContextGetUserSpaceToDeviceSpaceTransform: invalid context 0x0
<Error>: CGContextDrawTiledImage: invalid context 0x0
I looked in the docsa little but did not find any indication that i had to provide a Graphics context.
any pointers ?
Sandro.
