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:

CBCGPDiagramVisualContainerCtrl m_wndDiagramCtrl;

// 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:

CBCGPDiagramShape* pItem1 = new CBCGPDiagramShape(

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);

CBCGPDiagramShape* pItem2 = new CBCGPDiagramShape(

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:

CBCGPDiagramConnector* pConnector1_2 = new CBCGPDiagramConnector();

pConnector1_2->SetCurveType(CBCGPDiagramConnector::BCGP_CURVE_TYPE_LINE);

pConnector1_2->Connect(

pItem1, pItem2,

CBCGPDiagramConnector::CP_Right, CBCGPDiagramConnector::CP_Left);

pConnector1_2->InsertPoint (1, CBCGPPoint(165, 25));

pConnector1_2->InsertPoint (2, CBCGPPoint(165, 175));

pDiagram->AddConnector(pConnector1_2);

// Redraw diagram:

m_wndDiagramCtrl.RedrawWindow();
