[Qt-interest] Resize Frameless Widget Challenge

[Raja Rokkam]

Hi All,

      I tried to implement the resize of a frameless widget by capturing the
mouseMoveEvent:

void testRegionSharingWindow::mouseMoveEvent( QMouseEvent *evt )
{
    moveOffsetNew = this->mapFromGlobal(evt->globalPos());
    if( evt->buttons() == Qt::LeftButton )
    {
        if( ( evt->globalX() > ( this->geometry().bottomRight().x() - 150 )
) && ( evt->globalY() > ( this->geometry().bottomRight().y() - 150 ) ) )
        {
            int x = moveOffsetNew.x() - moveOffset.x() +
geometry().bottomRight().x();
            int y = moveOffsetNew.y() - moveOffset.y() +
geometry().bottomRight().y();
            int width = moveOffsetNew.x() - moveOffset.x() +
geometry().width();
            int height = moveOffsetNew.y() - moveOffset.y() +
geometry().height();
            this->setGeometry( x, y, width, height );
            evt->accept();
        }
        else
        {
            move( evt->globalPos() - dragging_position );
            evt->accept();
        }
    }
}
void testRegionSharingWindow::mousePressEvent( QMouseEvent *evt )
{
    if( evt->button() == Qt::LeftButton )
    {
        moveOffset = this->mapFromGlobal(evt->globalPos());
        invertedMoveOffset = this->rect().bottomRight() - moveOffset;
        orig_position = geometry().topLeft();
        evt_position = evt->globalPos();
        dragging_position = evt->globalPos() - frameGeometry().topLeft();
        evt->accept();
    }
}
However, I see a line:  *Warning:* Calling setGeometry() inside
resizeEvent<http://doc.qt.nokia.com/4.6/qwidget.html#resizeEvent>()
or moveEvent <http://doc.qt.nokia.com/4.6/qwidget.html#moveEvent>() can lead
to infinite recursion.

How can I go about the resizing as the chunk of code is not working as
expected ?


Thanks,
Raja.
