问题 I want to set rounded corners on a QDialog. Since it is a top-level window, border-radius doesn't work, so I've to do this : QRegion EnterPinDialog::roundedRect(const QRect& rect, int r) { QRegion region; // middle and borders region += rect.adjusted(r, 0, -r, 0); region += rect.adjusted(0, r, 0, -r); // top left QRect corner(rect.topLeft(), QSize(r*2, r*2)); region += QRegion(corner, QRegion::Ellipse); // top right corner.moveTopRight(rect.topRight()); region += QRegion(corner, QRegion:

问题 I could add a rounded corner border to my JDialog as in How to create a rounded title border in Java Swing. But it is still one color. I want to make the border looks like 3D. Here is how I tried.

问题 From the original question (below), I am now offering a bounty for the following: An AlphaComposite based solution for rounded corners. Please demonstrate with a JPanel . Corners must be completely transparent. Must be able to support JPG painting, but still have rounded corners Must not use setClip (or any clipping) Must have decent performance Hopefully someone picks this up quick, it seems easy. I will also award the bounty if there is a well-explained reason why this can never be done,

问题 I'm creating an iPad app for 3.2 and later. My app has an overlay view which has a semi-transparency that makes everything below it darker. In the middle of this view I am chopping a hole in this semi-transparency to let part of the background filter through unscathed, with this code: - (void)drawRect:(CGRect)rect { CGContextRef context = UIGraphicsGetCurrentContext(); CGRect intersection = CGRectIntersection(hole.frame, rect); CGContextClearRect(context, intersection); } Additionally, the

After reading quite a few posts, I see most solutions saying to use layer.cornerRadius = 10.0 When I do that I get this: It rounds the edges, but doesn't give me my desired goal. Any suggestion? 回答1: Swift 3 myButton.layer.cornerRadius = myButton.frame.height / 2 myButton.backgroundColor = UIColor.blue myButton.clipsToBounds = true myButton.tintColor = UIColor.white myButton.setTitle("Connect With Facebook",
