回答,如果所有可用的显示器的解决方案都是一样的。
对于AWT:
每个控制确实有该方法getMonitor(),从该屏幕位置获得可以从等计算:
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:
它只是我的原始代码中的一个片段。你应该问一下,如果返回值不为空,就像这样!
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;
}
