I have a frameless QQuickWindow, and I want to move it with the mouse by dragging. Before trying in my big application, I have created a simple test application to try what I found here, using cursor position from C++ class to avoid problems from QML:

But I failed with the code below. When I press over the red RECT and move the mouse, my yellow rect (root RECT) moves, but only inside the original size it had (in this case, 500x500)... What am I doing wrong?
Thanks in advance
In my main.cpp:
int main(int argc, char *argv[])
{
QtQuickControlsApplication a(argc, argv);
QQuickView* pView = new QQuickView();
CursorPosProvider mousePosProvider;
pView->rootContext()->setContextProperty("mousePosition", &mousePosProvider);
pView
->setSource
(QUrl("qrc:/Test.qml"));
pView->setFlags(Qt::FramelessWindowHint);
pView->show();
return a.exec();
}
int main(int argc, char *argv[])
{
QtQuickControlsApplication a(argc, argv);
QQuickView* pView = new QQuickView();
CursorPosProvider mousePosProvider;
pView->rootContext()->setContextProperty("mousePosition", &mousePosProvider);
pView->setSource(QUrl("qrc:/Test.qml"));
pView->setFlags(Qt::FramelessWindowHint);
pView->show();
return a.exec();
}
