I am using an NSTextField-with-image technique taken from the Drag N Drop
Outline View sample code, but when the custom cell is "edited" in an
NSTextField the drawing is offset down and to the right. Unedited drawing is
fine and editing in an NSTableView is fine. The following code seems most
relevant:
- (NSRect)titleRectForBounds:(NSRect)cellFrame
{
NSRect result;
if (self.validationError != nil)
{
CGFloat imageWidth = [self _imageSize].width;
result = cellFrame;
result.size.width -= (3 + imageWidth);
}
else
{
result = [super titleRectForBounds:cellFrame];
}
return result;
}
- (void)editWithFrame:(NSRect)aRect inView:(NSView *)controlView editor:(NSText
*)textObj delegate:(id)anObject event:(NSEvent *)theEvent
{
[super editWithFrame:[self titleRectForBounds:aRect] inView:controlView
editor:textObj delegate:anObject event:theEvent];
}
- (void)selectWithFrame:(NSRect)aRect inView:(NSView *)controlView
editor:(NSText *)textObj delegate:(id)anObject start:(NSInteger)selStart
length:(NSInteger)selLength
{
[super selectWithFrame:[self titleRectForBounds:aRect] inView:controlView
editor:textObj delegate:anObject start:selStart length:selLength];
}
- (void)drawWithFrame:(NSRect)cellFrame inView:(NSView *)controlView
{
if (self.validationError != nil)
{
NSRect imageFrame = [self imageRectForBounds:cellFrame];
[self.errorImage drawInRect:imageFrame fromRect:NSZeroRect
operation:NSCompositeSourceOver fraction:1.0 respectFlipped:YES hints:nil];
CGFloat newX = NSMaxX(imageFrame) + 3;
cellFrame.size.width = NSMaxX(cellFrame) - newX;
cellFrame.origin.x = newX;
}
[super drawWithFrame:cellFrame inView:controlView];
}
Note that validationError is always null, so I would expect everything to draw
properly. I vaguely recall mention of this offset issue at some point but Ic
an't seem to google any references to it. Any help is appreciated.
