回答,如果所有可用显示器的解决方案都相同。
对于AWT:
每个控件都有 getMonitor() 方法,从中可以计算屏幕位置,如下所示:
Monitor widgetMonitor = mTextWidget.getMonitor();
Rectangle monitorRect = widgetMonitor.getBounds();
if(monitorRect.x < 0){
// shown in left monitor, starting from the main monitor
}
if(monitorRect.x > monitorRect.width){
// shown in right monitor, starting from the main monitor
}
对于SWT:
这只是我原始代码的一个片段。您应该询问返回值是否不为 null 以及类似的东西!
int monitorWidth = 0;
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice[] screenDevices = ge.getScreenDevices();
if(screenDevices.length > 0){
monitorWidth = screenDevices[0].getDisplayMode().getWidth();
}
Point ownerLocationOnScreen = owner.getLocationOnScreen();
int screenMovingX = 0;
if(ownerLocationOnScreen.x < 0){
screenMovingX = -monitorWidth;
}
if(ownerLocationOnScreen.x > monitorWidth){
screenMovingX = monitorWidth;
}
