NSTextField带圆角？ [英] NSTextField with rounded corners?

问题描述

我尝试在NSTextField周围绘制圆角。

我已经子类化了 NSTextField

 <$ c 
 $ c>  - （void）drawRect：（NSRect）dirtyRect 
 {
 
 //黑色轮廓
 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]; 
 
} 
  

解决方案

做几乎一切正确。你只需要改变textField的单元格和半径匹配。看看这个：

   - （void）awakeFromNib {
 
 [[self cell] setBezelStyle ：NSTextFieldRoundedBezel]; 
} 
 
 
  - （void）drawRect：（NSRect）dirtyRect 
 {
 
 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：10 yRadius：10] angle：90]; 
 
} 
  

这很适合我。

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];

}

解决方案

You are doing almost everything correct. You just need to change the textField's cell and radius which match. Take a look at this:

-(void)awakeFromNib {

    [[self cell] setBezelStyle: NSTextFieldRoundedBezel];
}


- (void)drawRect:(NSRect)dirtyRect
{

    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:10 yRadius:10] angle:90];

}

This is working for me nicely.
