Dim background when opening JDialog in JFrame?

这可能吗？我尝试设置JFrame的不透明度并设置背景，但效果不好。有没有一些简单而优雅的方法？

Is that possible. I tried setting opacity of the Jframe and set background but it didn't work out. Is there some easy and elegant way?

通过将JFrame的glassPane设置为具有半透明背景的可见JPanel，您可以实现此目标：
static void setDimmed(JFrame frame,
boolean dimmed) {
JComponent newGlassPane = new JPanel();
if (dimmed) {
newGlassPane.setBackground(new Color(0x80000000, true));
}
frame.setGlassPane(newGlassPane);
newGlassPane.setVisible(dimmed);
}
英文:
You can achieve this by setting the JFrame’s glassPane to a visible JPanel with a translucent background:
static void setDimmed(JFrame frame,
boolean dimmed) {
JComponent newGlassPane = new JPanel();
if (dimmed) {
newGlassPane.setBackground(new Color(0x80000000, true));
}
frame.setGlassPane(newGlassPane);
newGlassPane.setVisible(dimmed);
}
