NSTextField with rounded corners?

Question

I'm trying to draw rounded corners around an NSTextField.

I've subclassed NSTextField, tried the code below, but without any result...

Any ideas?

- (void)drawRect:(NSRect)dirtyRect
{

    // black outline
    NSRect blackOutlineFrame = NSMakeRect(0.0, 0.0, [self bounds].size.width, [self bounds].size.height-1.0);
    NSGradient *gradient = nil;
    if ([NSApp isActive]) {
        gradient = [[NSGradient alloc] initWithStartingColor:[NSColor colorWithCalibratedWhite:0.24 alpha:1.0] endingColor:[NSColor colorWithCalibratedWhite:0.374 alpha:1.0]];
    }
    else {
        gradient = [[NSGradient alloc] initWithStartingColor:[NSColor colorWithCalibratedWhite:0.55 alpha:1.0] endingColor:[NSColor colorWithCalibratedWhite:0.558 alpha:1.0]];
    }
    [gradient drawInBezierPath:[NSBezierPath bezierPathWithRoundedRect:blackOutlineFrame xRadius:5 yRadius:5] angle:90];

}

Answer 1

It is better to subclass NSTextFieldCell to draw rounded corners to preserve NSTextField functionality, e.g:

- (void)drawWithFrame:(NSRect)cellFrame inView:(NSView *)controlView {
    NSBezierPath *betterBounds = [NSBezierPath bezierPathWithRoundedRect:cellFrame xRadius:CORNER_RADIUS yRadius:CORNER_RADIUS];
    [betterBounds addClip];
    [super drawWithFrame:cellFrame inView:controlView];
    if (self.isBezeled) {
        [betterBounds setLineWidth:2];
        [[NSColor colorWithCalibratedRed:0.510 green:0.643 blue:0.804 alpha:1] setStroke];
        [betterBounds stroke];
    }
}

Yields a nice rounded text field that works perfectly (if you had set it to draw a rectangle bezel in the first place, at least):
