Qt將窗體變為頂層窗體

//重載resizeEvent和moveEvent兩個函數，以保證窗體大小和位置改變后能時刻記住其位置
QRect curGemRect = mpWindow->geometry();

//激活mpWindow窗體為桌面的頂層窗體
Qt::WindowStates winStatus = Qt::WindowNoState;
if (mpWindow->windowState() & Qt::WindowMaximized)
{
    winStatus = Qt::WindowMaximized;
}
mpWindow->setWindowState(Qt::WindowMinimized);
mpWindow->setWindowState(Qt::WindowActive | winStatus);
mpWindow->setGeometry(curGemRect);
mpWindow->activateWindow();
mpWindow->raise();
