内容:
void moveWindowCenter(QWidget* widget)
{
if (widget) {
QRect re = QApplication::activeWindow()->screen()->availableGeometry();
widget->move((re.width() - widget->width()) / 2 + re.x(),
(re.height() - widget->height()) / 2);
}
}
----------------------------------
调用
widget.adjustSize();
moveWindowCenter(widget);
widget.show();
------------------------------------------
防坑提示：多屏幕时，弹出式窗口，可在当前屏幕居中，不会在其它屏幕居中

QDesktopWidget * deskTop = QApplication::desktop();
int curMonitor = deskTop->screenNumber(this);
QRect re = deskTop->availableGeometry(curMonitor);
widget->move((re.width() - widget->width()) / 2 + re.x(),
(re.height() - widget->height()) / 2);
