回答:如果所有可用监控器的解决方案相同。
对于
AWT
:
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
这只是对我的原始代码的一个剪贴。您应该询问返回值是否不为null,或者类似这样的问题!
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;
}
