        }

void omni::ui::TestInputPreview::mousePressEvent ( QMouseEvent *  event )

protectedvirtual

Mouse press event sets mouse position.

Reimplemented from omni::ui::GLView.

        {
            GLView::mousePressEvent(event);
            if (!input()) return;
            setRulerPos(event->pos());

            if (!input()) return;

            if (event->buttons() & Qt::LeftButton)
            {
                setRulerPos(event->pos());
            }
        }

void omni::ui::TestInputPreview::setRulerPos ( QPointF const &  _eventPos )

private

Set ruler position of input from widget coordinates.

        {
            if (!input()) return;

            QPointF _pos = screenPos(_eventPos);
            static_cast<input::TestImage*>(input())->setRulerPos(_pos);
            input()->update();
            triggerUpdate();
            emit inputChanged();
        }
