是什么导致Jframe在调整大小时闪烁? [英] What causes the Jframe to flicker while resizing?

问题描述

public class AspectRatio extends JFrame implements ComponentListener{

    public AspectRatio() {
        setSize(100, 100);
        setVisible(true);
        addComponentListener(this);
    }

    public static void main(String[] args){
        new AspectRatio();
    }

    @Override
    public void componentHidden(ComponentEvent e) {
        // TODO Auto-generated method stub

    }

    @Override
    public void componentMoved(ComponentEvent e) {
        // TODO Auto-generated method stub

    }

    @Override
    public void componentResized(ComponentEvent e) {
        int i = Math.max(getWidth(), getHeight());
        setSize(i, i);

    }

    @Override
    public void componentShown(ComponentEvent e) {
        // TODO Auto-generated method stub

    }

}

这里是您可以复制粘贴的示例.除了我自己，我无法代表任何人说话，但是当我调整大小时，JFrame忽然闪烁.有人知道是什么原因造成的吗?

Here is an example you can copy paste. Im cant speak for anyone but myself, but when i resize, the JFrame flickers wierdly. Does someone know what causing this?

谢谢你.

推荐答案

听起来像是自动刷新/自动重画的问题.拖动JPane时，它会尝试更新其所有组件的布局，从而导致闪烁.该讨论应具有解决方案:如何停止调整Jframe大小时自动重绘()

Sounds like an auto-refresh/auto-repaint issue. As you drag the JPane, it tries to update layout of all of its components, causing a flickering. This discussion should have the solution: How to stop the auto-repaint() when I resize the Jframe
