doublebuffered

问题 So in the game I\'m working on, I have a marble follow the mouse, but when it does this the screen flickers. The background includes two jpegs and 9 rectangles. How would I go about double buffering this? Here is the code for the main window. /** * Write a description of class Window here. * * @author (your name) * @version (a version number or a date) */ public class Window extends JApplet implements MouseMotionListener { private BufferedImage image; private BufferedImage side; private int

问题 EDIT TWO To prevent snarky comments and one-line answers missing the point: IFF it is as simple as calling setDoubleBuffered(true) , then how do I get access to the current offline buffer so that I can start messing with the BufferedImage\'s underlying pixel databuffer? I took the time to write a running piece of code (which looks kinda fun too) so I\'d really appreciate answers actually answering (what a shock ;) my question and explaining what/how this is working instead of one-liners and

问题 How can I set the protected DoubleBuffered property of the controls on a form that are suffering from flicker? 回答1: Here's a more generic version of Dummy's solution. We can use reflection to get at the protected DoubleBuffered property, and then it can be set to true . Note : You should pay your developer taxes and not use double-buffering if the user is running in a terminal services session (e.g. Remote Desktop) This helper method will not turn on double buffering if the person is running

问题 I added this to my form\'s constructor code: this.SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint | ControlStyles.DoubleBuffer, true); But it still shows ugly artifacts when it loads the controls, whenever they change (the form and its components change (need updating) often). What do I need to do differently? 回答1: This only has an effect on the form itself, not the child controls. If you have a lot of them then the time they need to take turns painting themselves
