示例1: setOpacity
import java.awt.peer.WindowPeer; //导入方法依赖的package包/类
/**
* Sets the opacity of the window.
* <p>
* The opacity value is in the range [0..1]. Note that setting the opacity
* level of 0 may or may not disable the mouse event handling on this
* window. This is a platform-dependent behavior.
* <p>
* The following conditions must be met in order to set the opacity value
* less than {@code 1.0f}:
* <ul>
* <li>The {@link GraphicsDevice.WindowTranslucency#TRANSLUCENT TRANSLUCENT}
* translucency must be supported by the underlying system
* <li>The window must be undecorated (see {@link Frame#setUndecorated}
* and {@link Dialog#setUndecorated})
* <li>The window must not be in full-screen mode (see {@link
* GraphicsDevice#setFullScreenWindow(Window)})
* </ul>
* <p>
* If the requested opacity value is less than {@code 1.0f}, and any of the
* above conditions are not met, the window opacity will not change,
* and the {@code IllegalComponentStateException} will be thrown.
* <p>
* The translucency levels of individual pixels may also be effected by the
* alpha component of their color (see {@link Window#setBackground(Color)}) and the
* current shape of this window (see {@link #setShape(Shape)}).
*
* @param opacity the opacity level to set to the window
*
* @throws IllegalArgumentException if the opacity is out of the range
* [0..1]
* @throws IllegalComponentStateException if the window is decorated and
* the opacity is less than {@code 1.0f}
* @throws IllegalComponentStateException if the window is in full screen
* mode, and the opacity is less than {@code 1.0f}
* @throws UnsupportedOperationException if the {@code
* GraphicsDevice.WindowTranslucency#TRANSLUCENT TRANSLUCENT}
* translucency is not supported and the opacity is less than
* {@code 1.0f}
*
* @see Window#getOpacity
