I have changed the structure, I have used a QQuickWidget with a QML inside, and now I have what I wanted. Here is my code in case anyone needs something similar
main.cpp
...
MovableWidget *view = new MovableWidget;
view->setSource(QUrl("qrc:/Test.qml"));
view->setWindowFlags(Qt::FramelessWindowHint);
view->show();
...
Test.qml
import QtQuick 2.0
Rectangle {
id: myWindow
width: 500; height: 500
color: "yellow"
Rectangle {
anchors.centerIn: parent
width: 200; height: 200
color: "red"
}
}
MovableWidget.cpp
#include "movableWidget.h"
#include <QMouseEvent>
// ************************************************** **************************
MovableWidget::MovableWidget(QWidget *parent)
: QQuickWidget(parent),
m_previousPos(0,0)
{
installEventFilter(this);
}
// ************************************************** **************************
bool MovableWidget::eventFilter(QObject *obj, QEvent *event)
{
if (event->type() == QEvent::MouseButtonPress)
{
m_previousPos = QCursor:os();
}
else if (event->type() == QEvent::MouseMove)
{
QMouseEvent *mouseEvent = static_cast<QMouseEvent*>(event);
if(mouseEvent->buttons() == Qt::LeftButton)
{
QPoint offset = m_previousPos - QCursor:os();
m_previousPos = QCursor:os();
move(pos() - offset);
}
}
return false;
}
