    Default Focus handling for the QwtPlot

    Hi,

    I noticed that I don't receive focus in and out events for the QwtPlot and the keyboard focus is not grabbed properly. To make it work, I have to fix two things:

    - Set setFocusPolicy(Qt::StrongFocus) on all diagrams. -> the diagram grabs the keyboard focus after a mouse click
    - Call setFocus() on the QwtPlot when e.g a mouse click happens -> fixes the focus in/out events

    I hope it helps for others.
