vertically aligning text in NSTableView row

Question

Hi all,

I have a small problem with NSTableView. When I am increasing height of a row in table, the text in it is aligned at top of row but I want to align it vertically centered!

Can anyone suggest me any way to do it ??

Thanks,

This is a simple code solution that shows a subclass you can use to middle align a TextFieldCell.

the header

#import <Cocoa/Cocoa.h>


@interface MiddleAlignedTextFieldCell : NSTextFieldCell {

}

@end

the code

@implementation MiddleAlignedTextFieldCell

- (NSRect)titleRectForBounds:(NSRect)theRect {
    NSRect titleFrame = [super titleRectForBounds:theRect];
    NSSize titleSize = [[self attributedStringValue] size];
    titleFrame.origin.y = theRect.origin.y - .5 + (theRect.size.height - titleSize.height) / 2.0;
    return titleFrame;
}

- (void)drawInteriorWithFrame:(NSRect)cellFrame inView:(NSView *)controlView {
    NSRect titleRect = [self titleRectForBounds:cellFrame];
    [[self attributedStringValue] drawInRect:titleRect];
}

@end
