我在组件上有一个
Java MouseListener来检测鼠标按压.如何知道鼠标按下哪个显示器？
@Override
public void mousePressed(MouseEvent e) {
// I want to make something happen on the monitor the user clicked in
}
我试图实现的效果是：当用户在我的应用程序中按下鼠标按钮时,弹出窗口会显示一些信息,直到鼠标释放.我想确保这个窗口位于用户点击的位置,但是我需要调整当前屏幕上的窗口位置,以便整个窗口可见.
解决方法
您可以从
java.awt.GraphicsEnvironment获取显示信息.您可以使用它来获取有关本地系统的信息.包括每个监视器的界限.
Point point = event.getPoint();
GraphicsEnvironment e
= GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice[] devices = e.getScreenDevices();
Rectangle displayBounds = null;
//now get the configurations for each device
for (GraphicsDevice device: devices) {
GraphicsConfiguration[] configurations =
device.getConfigurations();
for (GraphicsConfiguration config: configurations) {
Rectangle gcBounds = config.getBounds();
if(gcBounds.contains(point)) {
displayBounds = gcBounds;
}
}
}
if(displayBounds == null) {
//not found,get the bounds for the default display
GraphicsDevice device = e.getDefaultScreenDevice();
displayBounds =device.getDefaultConfiguration().getBounds
}
//do something with the bounds
...
