flicker

I have a JPanel which contains a lot of child components. While updating\adding new components to the parent JPanel I'd like to prevent it from repainting, how can this achieved? Try RepaintManager.currentManager(component).markCompletelyClean(component) . It will prevent the component from repainting. You might need to do this after each time you add new components. setVisible(false) update setVisible(true) you could try by using setIgnoreRepaint(boolean value) but it's a typical swing feature that can or cannot work (mainly because it depends from AWT so you never know). Otherwise you could

I figured out the solution for my previous question which landed me into new problem. In the following code im moving an image around a JFrame using arrow keys. but every time i press an arrow key the image seems to flicker which is quite noticeable when a key is pressed continuously. import java.awt.Graphics; import java.awt.event.KeyEvent; import java.awt.event.KeyListener; import java.awt.image.BufferedImage; import java.io.IOException; import javax.imageio.ImageIO; import javax.swing.JFrame; public class TestProgram extends JFrame implements KeyListener { private BufferedImage TestImage;

There are plenty of articles addressing flicker in Windows Forms. The majority recommend setting DoubleBuffered = true or setting a bunch of ControlStyle flags. However, none of these help reduce a TextBox flickering. Here are a couple of related questions: How to double buffer .NET controls on a form? How to eliminate flicker in Windows.Forms custom control when scrolling? To reproduce the issue, create a new WinForms project, add a TextBox , enable multi-line, disable word-wrap, add a bunch of text, set Anchor to Left+Right+Top+Bottom. Now run and resize. The text flickers. For text boxes

I have an app that has a ton of controls on it. And it has a massive amount of flicker, particularly on startup. I applied this fix to it. protected override CreateParams CreateParams { get { CreateParams cp = base.CreateParams; cp.ExStyle |= 0x02000000; // WS_EX_COMPOSITED return cp; } } This worked great - the flickering was reduced by a pretty unbelievable amount. However, the side effect is that the Minimize, Maximize and the Close buttons in the top right of the window don't animate when I move the mouse over or click on them (they still work though). This gives the app a hung feel. How
