[SOLVED] QwtPlotZoomer zoom out using QPushButtons?



  • Is is possible to zoom out after zooming in (any amount of stacks) to the stack index of 0 using a push button in a QwtPlotZoomer?

    My layout has 2 push buttons, 1 push button that turns the zoomer on and off, then I have another push button that will zoom all the way out to its original state. I cant find a way to do this...my application is going to be used on a touch screen so I cannot use push events...

    Any Qwt Guru's out there? Thanks!



  • @zoomer->zoom(0)@
    should help!



  • Thanks! I had actually figured out another way as well!

    @
    zoomer->setZoomStack(zoomer->zoomStack(), 0);
    @

    My other issue was I was not initializing my stack after I set my data points

    @
    setZoomBase();
    @
