FramelessWindowHint removes the abbility to drag/move the window

Kris Revi

So as the title says when using setWindowFlag(Qt::FramelessWindowHint); it also removes the abbility to drag/move the window!

by searching i found this here on this Qt Forum but it's from 2013 and i suspect it's old as i get some errors when trying this code

private:
    void mousePressEvent(QMouseEvent *event);
    void mouseMoveEvent(QMouseEvent *event);
    int m_nMouseClick_X_Coordinate;
    int m_nMouseClick_Y_Coordinate;
And this to .cpp file:

void MainWindow::mousePressEvent(QMouseEvent *event) {
    m_nMouseClick_X_Coordinate = event->x();
    m_nMouseClick_Y_Coordinate = event->y();
}

void MainWindow::mouseMoveEvent(QMouseEvent *event) {
    move(event->globalX()-m_nMouseClick_X_Coordinate,event->globalY()-m_nMouseClick_Y_Coordinate);
}

errors i get is

Code:
    m_nMouseClick_X_Coordinate = event->x();
    m_nMouseClick_Y_Coordinate = event->y();
    move(event->globalX()-m_nMouseClick_X_Coordinate,event->globalY()-m_nMouseClick_Y_Coordinate);

Error:
    member access into incomplete type 'QMouseEvent'

Hi
Yes when removing the caption, one can no longer drag it around.

To fix you compile error do
#include "QMouseEvent"

You also must add resize if needed.

One of the better version of this, i know is
