当用户单击JFrame的角落来调整大小并拖动鼠标时，JFrame会根据用户拖动时鼠标的当前位置重绘。你怎么听这些事件？
下面是我目前尝试的：
public final class TestFrame extends JFrame {
public TestFrame() {
this.addComponentListener(new ComponentAdapter() {
public void componentResized(ComponentEvent e) {
// This is only called when the user releases the mouse button.
System.out.println("componentResized");
}
});
}
// These methods do not appear to be called at all when a JFrame
// is being resized.
@Override
public void setSize(int width, int height) {
System.out.println("setSize");
}
@Override
public void setBounds(Rectangle r) {
System.out.println("setBounds A");
}
@Override
public void setBounds(int x, int y, int width, int height) {
System.out.println("setBounds B");
}
}
如何确定和约束用户如何调整窗口(基于窗口的当前宽高比)的大小，当他们围绕鼠标拖动？
