CCWAnnotation

[thy31]

Bonjour

I tried to add annotations to CWGraph , but I cannot modifiy Shape & Arrow.

I tried to modify the example project in Ui\Graph\Annotations and all works, but not in my project (CWGraph allocated dynamically)

        VARIANT PlotIdx;
        ::VariantInit(&PlotIdx);
        PlotIdx.vt = VT_I4;
        PlotIdx.lVal = 1;


        VARIANT XCoord;
        ::VariantInit(&XCoord);
        XCoord.vt = VT_R8;

        VARIANT YCoord;
        ::VariantInit(&YCoord);
        YCoord.vt = VT_R8;
       
        XCoord.dblVal = GetCursorXPosition(1,FALSE);
        YCoord.dblVal = 1.0;

        CCWShape l_Shape;
        l_Shape.SetColor(0x00ff00);
        l_Shape.SetLineColor(0x0000ff);
        l_Shape.SetPointStyle(CNiShape::Point);
        l_Shape.SetCoordinates(XCoord, YCoord);

        CCWArrow l_Arrow;
        l_Arrow.SetColor(0xff0000);
        l_Arrow.SetHeadStyle(CNiArrow::Diamond);
        l_Arrow.SetTailStyle(CNiArrow::Diamond);
       
        CCWAnnotation l_Annotation = m_GraphComponent->GetAnnotations().Add();
        l_Annotation.SetPlot(m_GraphComponent->GetPlots().Item(PlotIdx));
        l_Annotation.SetSnapMode(CNiAnnotation::SnapAnchoredToPoint);
        l_Annotation.SetCoordinateType(CNiAnnotation::AxesCoordinates);
        l_Annotation.SetBuiltinStyle(CNiAnnotation::ArrowOnly);
        l_Annotation.SetEnabled(TRUE);
        l_Annotation.SetVisible(TRUE);
        l_Annotation.SetPointIndex(GetCursorXPointIndex(1));
        l_Annotation.SetShape(l_Shape); // doesn't work
        l_Annotation.SetArrow(l_Arrow); // doesn't work also

 Is there somethig else to do ?

The result is always the same (I cannot change shape & arrow)

 

The version of CWGraph is v8.1.11 Release(472)(602).

I finally found the solution.

these 2 lines have no effect (do these 2 functions are useless ?)

l_Annotation.SetShape(l_Shape);
l_Annotation.SetArrow(l_Arrow);

The solution was :

        l_Annotation.GetShape().SetColor(0x00ff00);
        l_Annotation.GetShape().SetLineColor(0x0000ff);
        l_Annotation.GetShape().SetPointStyle(CNiShape::Point);
        l_Annotation.GetShape().SetCoordinates(XCoord, YCoord);

        l_Annotation.GetArrow().SetColor(0xff0000);
        l_Annotation.GetArrow().SetHeadStyle(CNiArrow::Diamond);
        l_Annotation.GetArrow().SetTailStyle(CNiArrow::Diamond);
