[英]Java JComponent lag on resize
Can anyone give insight as to why a JPanel that is drawing simple shapes such as rectangles, in small quantity, could lag noticeably when resizing the frame? 谁能给出洞察力,为什么在调整框架大小时,绘制少量矩形等简单形状的JPanel会明显滞后?
I think that by adding an event for window resize and timing the resize to 1/10 s or so, I could solve the problem. 我认为,通过添加一个事件来调整窗口大小并将定时大小调整为1/10秒左右,我可以解决问题。 But I'm not so sure.
但是我不太确定。
EDIT: 编辑:
After reviewing the example code I found that the resize lag is due to having a handler that scales drawn objects by getting the height and width of the screen. 查看示例代码后,我发现调整大小滞后是由于具有一个处理程序,该处理程序通过获取屏幕的高度和宽度来缩放绘制的对象。
this.addComponentListener(new ComponentAdapter() {
public void componentResized(ComponentEvent e) {
setScale( getHeight(), getWidth() );
}
});
Is there any way to smooth the resize lag? 有什么方法可以缓解调整大小的延迟吗?
