Thanks for your respons, but I need the exacte size in points, which means
drawing with the right Font etc.
So here's where I am
in
- (CGFloat)tableView:(NSTableView *)tableView heightOfRow:(NSInteger)row
I'm calling a function which calculates the height needed for the text and
that's what I'm returning:
-(float)heightForStringDrawing:(NSString*)theTextField withFont:(NSFont*)myFont
forWidth:(float)myWidth{
NSTextStorage *textStorage = [[[NSTextStorage alloc]
initWithString:theTextField] autorelease];
NSTextContainer *textContainer = [[[NSTextContainer alloc]
initWithContainerSize: NSMakeSize(myWidth, FLT_MAX)] autorelease];
NSLayoutManager *layoutManager = [[[NSLayoutManager alloc] init]
autorelease];
[layoutManager addTextContainer:textContainer];
[textStorage addLayoutManager:layoutManager];
[textStorage addAttribute:NSFontAttributeName value:myFont
range:NSMakeRange(0,[textStorage length])];
[textContainer setLineFragmentPadding:0.0];
[layoutManager glyphRangeForTextContainer:textContainer];
return [layoutManager
usedRectForTextContainer:textContainer].size.height;
}
BUT, I'm getting row clippings, and the strange thing if as soon as I'm
clicking on any cell, everything comes back to good order.
Any help appreciated,
Michael
