Status bar scroll control issue

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello,
i have created slider control in a status bar in my Mdi application.

pZoomPane = (CXTPStatusBarSliderPane*)m_wndStatusBar.AddIndicator(new CXTPStatusBarSliderPane(), ID_STATUSBAR_ZOOMSLIDER);pZoomPane->SetBeginGroup(FALSE);pZoomPane->SetWidth(130);pZoomPane->SetPos(100); pZoomPane->SetRange(10, 349);pZoomPane->SetCaption(_T("&Zoom Slider"));pZoomPane->SetTooltip(_T("Zoom"));pZoomPane->SetTooltipPart(XTP_HTSCROLLUP, _T("Zoom Out"));pZoomPane->SetTooltipPart(XTP_HTSCROLLDOWN, _T("Zoom In"));

I write the event handler for it like this.

ON_NOTIFY(XTP_SBN_SCROLL, ID_STATUSBAR_ZOOMSLIDER, OnZoomSliderScroll)

We have our zoomIn(),zoomOut() functions in our application. i just have to map these function to scroll position.
But i am not able to trace the movement of the scroll,wheather it is in forward direction or in backward,so i am not able to call our zoomIn and ZoomOut Functions accordingly.
Can i trace the movement in ON_NOTIFY event handler? or i will have to write the OnScroll() event handler compulsaryly?

Please guide me accordingly.

Thanks And Regards,
Vijay.

	Does your application not have a zoomTo() or similar function where you can set the zoom % directly? Without that, you'll need to save the prior position and compute the difference, and call zoomIn or zoomOut the appropriate number of times. In this case, you'll want the range to be (-outmax, +inmax), where outmax is the most number of times you can zoom out and inmax is the most times you can zoom in.
