我正在尝试在 a 内创建一个NSImage
或NSImageCell
带有圆角的NSTableView
. 我什么都做不了。这是迄今为止我在自定义中最好的NSCell
:
- (void)drawInteriorWithFrame:(NSRect)frame inView:(NSView *)controlView {
if (thumbnailLink) {
NSURL *url = [NSURL URLWithString:thumbnailLink];
if (url) {
NSRect imageFrame = [self _imageFrameForInteriorFrame:frame];
NSImage *image = [[NSImage alloc] initWithContentsOfURL:url];
[image setScalesWhenResized:YES];
[image setSize:NSMakeSize(IMAGE_HEIGHT, IMAGE_WIDTH)];
[NSGraphicsContext saveGraphicsState];
imageFrame = NSInsetRect(imageFrame, 1, 1);
NSBezierPath *clipPath = [NSBezierPath bezierPathWithRoundedRect:imageFrame cornerRadius:5.0];
[clipPath setWindingRule:NSEvenOddWindingRule];
[clipPath addClip];
[NSGraphicsContext restoreGraphicsState];
[image drawInRect:imageFrame fromRect:NSMakeRect(0, 0, 0, 0) operation:NSCompositeSourceIn fraction:1.0];
[image release];
}
}
...
关于如何做到这一点的任何想法?
