TdxCustomFlowChart.CreateConnection(TdxFcObject,TdxFcObject,Byte,Byte) Method

Creates a new connection between two specified chart symbols.

Declaration

function CreateConnection(OSrc: TdxFcObject; ODst: TdxFcObject; PSrc: Byte; PDst: Byte): TdxFcConnection;

Parameters

Name	Type	Description
OSrc	TdxFcObject	The source chart symbol.
ODst	TdxFcObject	The destination chart symbol.
PSrc	Byte	The attachment point of the source chart symbol (OSrc).
PDst	Byte	The attachment point of the destination chart symbol (ODst).

Returns

Type	Description
TdxFcConnection	The created connection between OSrc and ODest chart symbols.

Remarks

Call the CreateConnection function to bind OSrc and ODest chart symbols.

Code Example: Connect two Advanced Shapes

The following code example connects two advanced shapes:

Delphi

var
  AConnection: TdxFcConnection;
  AObj1, AObj2: TdxFcObject;
begin
  // Provides access to the first shape in the control
  AObj1 := dxFlowChart1.Objects[0];
  AObj2 := dxFlowChart1.Objects[1];
  // Attaches the connection to shapes at the specified points
  AConnection := dxFlowChart1.CreateConnection(AObj1,AObj2,0,2);
  // Sets one-pixel width for the connection line
  AConnection.PenWidth := 1;
  // Sets the dashed line for the connection
  AConnection.PenStyle := psDash;
  // Sets the straight line for the connection
  AConnection.Style := fclStraight;
  // Sets text to display within the connection
  AConnection.Text := 'Connection';
  // Fills the connection with the gray color
  AConnection.Color := clGray;
  // Assigns no shape to the connection's start arrow
  AConnection.ArrowSource.ArrowType := fcaNone;
  // Assigns the "Filled Arrow" shape to the connection's destination arrow
  AConnection.ArrowDest.ArrowType := fcaFilledArrow;
end;

C++

{
  // Provides access to the first shape in the control
  TdxFcObject *AObj1 = dxFlowChart1->Objects[0];
  TdxFcObject *AObj2 = dxFlowChart1->Objects[1];
  // Attaches the connection to shapes at the specified points 
  TdxFcConnection *AConnection = dxFlowChart1->CreateConnection(AObj1, AObj2, 0, 2);
  // Sets one-pixel width for the connection line
  AConnection->PenWidth = 1;
  // Sets the dashed line for the connection
  AConnection->PenStyle = psDash;
  // Sets the straight line for the connection
  AConnection->Style = fclStraight;
  // Sets text to display within the connection
  AConnection->Text = "Connection";
  // Fills the connection with the gray color
  AConnection->Color = clGray;
  // Assigns no shape to the connection's start arrow
  AConnection->ArrowSource->ArrowType = fcaNone;
  // Assigns the "Filled Arrow" shape to the connection's destination arrow
  AConnection->ArrowDest->ArrowType = fcaFilledArrow;
