Mouse dragged widget without title

How to create mouse dragged widget without title?

Reimplement QWidget::mousePressEvent() and QWidget::mouseMoveEvent().

Here's some "pseudo":

Code:

---

// a frameless window
setWindowFlags(Qt::FramelessWindowHint);
 
// member variable
QPoint offset;
 
mousePressEvent()
{
    // offset from top left corner
    offset = event->pos();
}
 
mouseMoveEvent()
{
    // move to mouse pos - calculated offset
    move(event->globalPos() - offset);
}

---

Thank you!
