Subversion editor view

Today I've played with the idea of a new Subversion editor view in the Delphi 2006 IDE.
To add a new editor view to the editor, you have to implement ICustomEditorView interface and register it with a RegisterEditorView call.
You'll need to add EditorViewSupport unit to your uses clause. This unit is only available through designide.dcp; there is no source code. But you can use Code Insight and Help Insight to see what methods are declared in the interface:

  TSvnEditorView = class(TInterfacedObject, ICustomEditorView, ICustomEditorFrameView)
  private
    { ICustomEditorView }
    function GetCanCloneView: Boolean;
    function GetCaption: string;
    function GetPriority: Integer;
    function GetStyle: TEditorViewStyle;
    function GetViewIdentifier: string;
    procedure Display(const AContext: IInterface; AViewObject: TObject);
    function EditAction(const AContext: IInterface; Action: TEditAction; AViewObject: TObject): Boolean;
    function GetEditState(const AContext: IInterface; AViewObject: TObject): TEditState;
    function Handles(const AContext: IInterface): Boolean;
    procedure Hide(const AContext: IInterface; AViewObject: TObject);
    procedure ViewClosed(const AContext: IInterface; AViewObject: TObject);

    { ICustomEditorFrameView }
    function GetFrameClass: TCustomFrameClass;
  end;
