How to set absolute layout of the widgets in different qt app

[choujayyl]

I use a QDeclarativeView * view to show my QML. app1 and app2 are two applications that show QML, and I want app1 to move out of screen and back, then lowers app1 to the bottom of app2.

The issue is:
•If I don’t use setWindowFlags(Qt::X11BypassWindowManagerHint), app1 cannot move out the screen
•If I use setWindowFlags(Qt::X11BypassWindowManagerHint),view->lower() doesn’t work

It seems let the app1 under the lowest, include under the Desktop that cannot see the app1.

Here is my app1 code :
@int main(int argc, char argv[])
{
QApplication a(argc, argv, true);
QDeclarativeView view;
QDeclarativeContext context;
QDeclarativeEngine engine;
Connector* connector;

view = new QDeclarativeView();

connector = new Connector();
context = view->rootContext();
context->setContextProperty("Connector", connector);


context->setContextProperty("gRadioQMLDir", QDir::currentPath());
view->setWindowFlags( Qt::FramelessWindowHint |Qt::X11BypassWindowManagerHint);
view->setSource(QUrl::fromLocalFile("qml/Main.qml"));
view->setViewportUpdateMode(QGraphicsView::MinimalViewportUpdate);

view->show();
view->lower();

 return a.exec();
