Thread: Mouse lock inside window/widget

  1. #1

    Default Mouse lock inside window/widget

    I am trying to stop the mouse from leaving the window. This is useful for first person cameras in OpenGL, as well as full screen applications with multiple monitors. I mostly am just looking to keep it inside the window, however keeping the mouse inside a widget could also be useful to know.

    You are looking vor leaveEvent().

    So: just reimplement the leaveEvent, grab your mouse pointer by its neck and put it back where it belongs, I'd say.
    For that: http://qt-project.org/doc/qt-4.8/qcursor.html
    But done that I never have....
