How to Add Text Display in CATIA by CAA

As shown in the diagram above, this demonstrates how to add text information at specified positions in the interface. C++

// 1. Obtain the Viewer instance
CATViewer* pViewer = nullptr;
CATFrmLayout* pCurrentLayout = CATFrmLayout::GetCurrentLayout();

if (pCurrentLayout != nullptr)
{
    CATFrmWindow* pCurrentWindow = pCurrentLayout->GetCurrentWindow();
    if (pCurrentWindow != nullptr)
    {
        pViewer = pCurrentWindow->GetViewer();
    }
}

// 2. Create 2D Bag Representation container
CAT2DBagRep* pRep = new CAT2DBagRep();
pViewer->AddRep(pRep);

// 3. Configure text properties
const float textPosition[2] = {10.0f, -10.0f};
const CATUnicodeString displayText = "112233";
const CAT2DAnnotationAnchor anchorType = BASE_LEFT;

// Initialize text annotation with positioning parameters
CAT2DAnnotationTextRep* pTextAnnotation = new CAT2DAnnotationTextRep(
    textPosition,
    displayText,
    anchorType
);

// 4. Add text element to visualization and update display
if (pTextAnnotation != nullptr)
{
    pRep->AddChild(*pTextAnnotation);
}

// Refresh visualization pipeline
pViewer->Draw();
pViewer->Reframe();
