What's new

version 2.4

• New: TDiagramButtons control: a new diagram toolbar with a more Visio-like appearance. Only for Delphi version 2005 and higher.
• New: TDiagramAlign action, for making easy alignment and spacing of blocks
• New: TDiagramEditor component. A ready-to-use and full-featured diagram editor including the new Visio-like toolbar (Delphi 2005 or higher) and new alignment palette
• New: TatDiagram.KeyActions property
• New: TTextCell.Visible property
• New: TatDiagram.OnAfterDrawBlock event
• New: TDiagramControl.IsBackgroundControl property
• New: TDiagramControl.CalcSize virtual method
• New: TSnapGrid.Force property
• New: TLineArrow.DiagramLine property made public
• New: AIgnoreZoom parameter in TatDiagram.HandleAtPos method
• Improved: Now the demo just uses the TDiagramEditor component
• Improved: Warnings removed
• Fixed: Shadow of blocks were sometimes being drawn with wrong pen width.

version 2.3

• New: Support for C++Builder 2007 added
• New: TatDiagram.ConnectionLineId method allows automatic linkpoint linking without need to choose a line object from the toolbar (see DiagramDemo) 
• New: TatDiagram.PageLines property allows to make page lines visible to indicate the printed page size. 
• New: TatDiagram.AutoPage property allows automatic redimension of diagram area according to the printed page size. 
• New: TLiveDiagram save/load state mechanism. The state of the chart being executed can be saved and retrieved later by using LoadState methods and OnSaveState event. Any live block can signal the chart to be saved (by setting ExecInfo.WaitState property in OnExecuteEx event). 
• New: TLiveDiagram execution paths concept. A live diagram can have multiple execution paths, by the use of TLiveForkBlock (to split a single execution path in multiple execution paths) and TLiveJoinBlock (to join multiple execution paths in a single execution path) 
• New: TDiagramControl.MakeVisible method 
• New: TatDiagram.MakeControlVisible method 
• New: PageUp/PageDown key support for scrolling the diagram area. 
• New: TDiagramToolbar.ButtonSize property 
• New: dbLines in TDiagramToolbarButtons allows to make the diagram toolbar to show only lines (to be used in conjunction with TDiagramToolbar.Mode property 
• New: TDiagramToolbar.Mode property (tmObjects, tmConnections). It makes it possible to use the diagram toolbar to choose the line object for automatic connections (to be used in conjunction with TatDiagram.ConnectionLineId) 
• New: kmLinesOnly item in TKeepInsertingMode for the diagram toolbar. 
• New: TDiagramConnectionID action 
• New: AsText parameter in TatDiagram.LoadFromStream and TatDiagram.SaveToStream methods allows text format saving of diagram content 
• New: public methods TDiagramControl.HasDefaultTextCell and TDiagramControl.DefaultTextCell. 
• New: TLiveDiagram.OnExecuteEx event. This event passes a TExecuteNodeInfo object which gives more flexibility over the execution flow and state saving. 
• New: TLiveDiagram: TDiagramState type dsView shows the current state of live diagram chart 
• New: TLiveDiagram.MakeActiveNodeVisible shows the current node being executed in diagram 
• New: TLiveDiagram.ViewStateMode property specifies if the start, end or current executed node (block) will be highlighted 
• New: live diagram fork block demo 
• Improved: simple (main) demo has a connection toolbar for choosing automatic connections 
• Improved: clipboard operations in live diagram now supported with default diagram actions 
• Fixed: OnDControlMouseUp not being called when right-button was clicked.  

version 2.2

Frequently asked questions

Code snippets for frequently asked questions:

Adding restrictions to diagram blocks 

ADControl.Restrictions := ADControl.Restrictions + [crNoMove];

Programmatically adding a line between 2 diagram block links

MyLine := TDiagramLine.Create(Self);
with MyLine do
begin
  Name := 'MyLineName';
  Diagram := atDiagram1;
  SourceLinkPoint.AnchorLink := SomeBlock.LinkPoints[0]; //link start point to someblock
  TargetLinkPoint.AnchorLink := AnotherBlock.LinkPoints[1]; // link end point to anotherblock
end;

Creating and inserting a diagram block programmatically

MyBlock := TDiagramBlock.Create(Self);
with MyBlock do
begin
  Name := 'MyblockName';
  Left := 10;
  Top := 10;
  Width := 150;
  Height := 50;
  Diagram := atDiagram1;
end;

Using a metafile as block

with atDiagram1.Blocks[0] do
begin
  Shape := bsNoShape;
  Metafile.LoadFromFile('mymetafile.wmf');
end;

Adding metafiles as block on the toolbar

procedure TForm1.atDiagram1InsertDControl(Sender: TObject; ADControl: TDiagramControl);
begin
  if UpperCase(ADControl.DControlID) = 'MYBLOCK' then
  begin
    With ADControl As TDiagramBlock do
    begin
      Shape := bsNoShape;
      Metafile.LoadFromFile('C:\MyMetafile.wmf');
    end;
  end else
  if UpperCase(ADControl.DControlID) = 'MYOTHERBLOCK' then
  begin
    With ADControl As TDiagramBlock do
    begin
    Color := clYellow;
    end;
  end;
end;

initialization

RegisterDControl(TDiagramBlock, 'MyBlock', 'This is a caption for my block', 'My category');
RegisterDControl(TDiagramBlock, 'MyOtherBlock', 'This is a caption for my other block', 'My category');
