CBCGPDiagramVisualContainer

Detailed Description

The CBCGPDiagramVisualContainer class encapsulates the diagram object. A diagram has a visible area and contains diagram items. Call SetRect() to specify visible area. Call AddItem() to add a new diagram item. Call AddConnector() to add a new connector.

A code below demonstrates how to create the following simple diagram:

To take advantage of diagram control perform the following steps:

Copy
// Declare a member variable of CBCGPDiagramVisualContainerCtrl type:
// Call CBCGPBaseVisualCtrl::Create (CBCGPBaseVisualCtrl is the base class):
m_wndDiagramCtrl.Create(rect, pParentWnd, nID);
// Setup and use the Diagram visual object with the GetDiagramContainer accessor:
CBCGPDiagramVisualContainer* pDiagram = (CBCGPDiagramVisualContainer*) m_wndDiagramCtrl.GetVisualContainer();
pDiagram->SetFillBrush(CBCGPBrush(CBCGPColor::WhiteSmoke, CBCGPColor::White, CBCGPBrush::BCGP_GRADIENT_DIAGONAL_LEFT));
pDiagram->SetOutlineBrush(CBCGPBrush(CBCGPColor::Gray));
pDiagram->EnableInplaceEdit();
pDiagram->EnableScrollBars();
// Add items to the diagram:
CBCGPRect(CBCGPPoint(30, 10), CBCGPSize(90, 30)),
CBCGPBrush(CBCGPColor::PaleTurquoise, CBCGPColor::White, CBCGPBrush::BCGP_GRADIENT_DIAGONAL_LEFT),
CBCGPBrush(CBCGPColor::PaleTurquoise), CBCGPDiagramShape::Box);
pItem1->AddTextData(_T("Item A"));
pDiagram->AddItem(pItem1);
CBCGPRect(CBCGPPoint(200, 160), CBCGPSize(90, 30)),
CBCGPBrush(CBCGPColor::PaleTurquoise, CBCGPColor::White, CBCGPBrush::BCGP_GRADIENT_DIAGONAL_LEFT),
CBCGPBrush(CBCGPColor::PaleTurquoise), CBCGPDiagramShape::Box);
pItem2->AddTextData(_T("Item B"));
pDiagram->AddItem(pItem2);
// Add connectors to the diagram:
pConnector1_2->Connect(
pItem1, pItem2,
pConnector1_2->InsertPoint (1, CBCGPPoint(165, 25));
pConnector1_2->InsertPoint (2, CBCGPPoint(165, 175));
pDiagram->AddConnector(pConnector1_2);
// Redraw diagram:
m_wndDiagramCtrl.RedrawWindow();
