	DlgTst* dlg2 = new DlgTst(this);
//	dlg2->setModal(Qt::ApplicationModal);
	dlg2->show();

嵌入子对话框

	setWindowFlags(Qt::CustomizeWindowHint | Qt::FramelessWindowHint);

保持对话框前置，类似于MFC的SetOwner

	setWindowFlags(Qt::Dialog);

PostMessage
signal slot connect的默认行为类似于SendMessage，如果要实现PostMessage的行为，connect时加参数Qt::QueuedConnection。
