TeeTree includes a powerful animation framework through the TreeAnimate component, allowing you to create smooth, professional animations for tree diagrams.

​
Basic Animation Setup

Add the TreeAnimate component to enable animations: 
uses TreeAnimate, TreeAnimateEditor;

type
  TAnimationsForm = class(TForm)
    Tree1: TTree;
    TreeAnimate1: TTreeAnimate;
    // Animation components
    TFontSizeAnimation1: TFontSizeAnimation;
    TTransparencyAnimation2: TTransparencyAnimation;
    TVisibleAnimation3: TVisibleAnimation;
    TMovementAnimation4: TMovementAnimation;
  end;

​
Playing Animations

Control animation playback: 
procedure TAnimationsForm.SBPlayClick(Sender: TObject);
begin
  TreeAnimate1.Play;
end;

procedure TAnimationsForm.SBStopClick(Sender: TObject);
begin
  TreeAnimate1.Stop;
end;

// Handle animation events
procedure TAnimationsForm.TreeAnimate1Play(Sender: TObject);
begin
  SBStop.Enabled := True;
  SBPlay.Enabled := False;
end;

procedure TAnimationsForm.TreeAnimate1Stop(Sender: TObject);
begin
  SBStop.Enabled := False;
  SBPlay.Enabled := True;
  SBPlay.Down := False;
end;

​
Animation Properties

​
Loop Animation

Make animations repeat continuously: 
procedure TAnimationsForm.CheckBox1Click(Sender: TObject);
begin
  TreeAnimate1.Loop := CheckBox1.Checked;
end;

​
Animation Speed

Control playback speed: 
procedure TAnimationsForm.TrackBar1Change(Sender: TObject);
begin
  TreeAnimate1.Speed := TrackBar1.Position;
end;

​
Animation Types

TeeTree provides various animation types:

​
Font Size Animation

Animate text size changes: 
TFontSizeAnimation1.FromSize := 8;
TFontSizeAnimation1.ToSize := 24;
TFontSizeAnimation1.Duration := 1000; // milliseconds
TFontSizeAnimation1.Shape := TreeNodeShape1;

​
Transparency Animation

Fade nodes in or out: 
TTransparencyAnimation2.FromTransparency := 0;
TTransparencyAnimation2.ToTransparency := 100;
TTransparencyAnimation2.Duration := 500;
TTransparencyAnimation2.Shape := TreeNodeShape2;

​
Visibility Animation

Show or hide nodes: 
TVisibleAnimation3.Visible := True; // or False
TVisibleAnimation3.Duration := 300;
TVisibleAnimation3.Shape := TreeNodeShape3;

​
Movement Animation

Move nodes to new positions: 
TMovementAnimation4.ToX := 200;
TMovementAnimation4.ToY := 100;
TMovementAnimation4.Duration := 1000;
TMovementAnimation4.Shape := TreeNodeShape4;

​
Color Animation

Animate color changes: 
// Node color animation
TNodeColorAnimation8.FromColor := clBlue;
TNodeColorAnimation8.ToColor := clRed;
TNodeColorAnimation8.Duration := 800;
TNodeColorAnimation8.Shape := TreeNodeShape1;

// Tree background color animation
TTreeColorAnimation7.FromColor := clWhite;
TTreeColorAnimation7.ToColor := clSilver;
TTreeColorAnimation7.Duration := 1000;

​
Text Animation

Animate text changes: 
// Add text gradually
TAddTextAnimation14.Text := 'Hello World';
TAddTextAnimation14.Duration := 2000;
TAddTextAnimation14.Shape := TreeNodeShape5;

// Move text position
MoveTextAnimation20.ToX := 50;
MoveTextAnimation20.ToY := 30;
MoveTextAnimation20.Duration := 800;

​
Text Angle Animation

Rotate text: 
TTextAngleAnimation19.FromAngle := 0;
TTextAngleAnimation19.ToAngle := 360;
TTextAngleAnimation19.Duration := 2000;
TTextAngleAnimation19.Shape := ArrowRightShape1;

​
Zoom Animation

Scale nodes up or down: 
NodeZoomAnimation21.FromZoom := 100; // percentage
NodeZoomAnimation21.ToZoom := 200;
NodeZoomAnimation21.Duration := 1000;
NodeZoomAnimation21.Shape := TreeNodeShape1;

​
Pause Animation

Add delays between animations: 
TPauseAnimation10.Duration := 500; // wait 500ms

​
Animation Editor

Use the visual animation editor to create complex sequences: 
procedure TAnimationsForm.Button2Click(Sender: TObject);
begin
  TTreeAnimateEditor.ModalShow(Self, TreeAnimate1);
end;

​
Creating Animation Sequences

Combine multiple animations for complex effects: 
procedure CreateAnimationSequence;
begin
  with TreeAnimate1 do
  begin
    // Step 1: Fade in
    TTransparencyAnimation.Create(TreeAnimate1);
    
    // Step 2: Move to position
    TMovementAnimation.Create(TreeAnimate1);
    
    // Step 3: Change color
    TNodeColorAnimation.Create(TreeAnimate1);
    
    // Step 4: Pause
    TPauseAnimation.Create(TreeAnimate1);
    
    // Step 5: Zoom
    NodeZoomAnimation.Create(TreeAnimate1);
  end;
end;

​
Animated GIF Support

Display animated GIFs in nodes: 
uses GIFImage; // or GIFImg for newer Delphi versions

procedure TAnimatedGIFForm.CheckBox1Click(Sender: TObject);
begin
  if ImageShape1.Image.Graphic is TGIFImage then
  with TGIFImage(ImageShape1.Image.Graphic) do
  begin
    {$IFDEF D105}
    Animate := CheckBox1.Checked;
    {$ELSE}
    if CheckBox1.Checked then
      DrawOptions := DrawOptions + [goAnimate]
    else
      DrawOptions := DrawOptions - [goAnimate];
    {$ENDIF}
  end;
end;

procedure TAnimatedGIFForm.TrackBar1Change(Sender: TObject);
begin
  if ImageShape1.Image.Graphic is TGIFImage then
  with TGIFImage(ImageShape1.Image.Graphic) do
    AnimationSpeed := TrackBar1.Position;
end;

​
Performance Tips

  • Limit simultaneous animations for better performance
  • Use pause animations to stagger effects
  • Consider frame rate impact on complex trees
  • Short animations (200-500ms): UI feedback
  • Medium animations (500-1000ms): Transitions
  • Long animations (1000-3000ms): Presentations
  • Enable BufferedDisplay for smoother animations
  • Use hardware acceleration when available

​
Common Animation Patterns

​
Attention-Grabbing Effect

procedure HighlightNode(Node: TTreeNodeShape);
begin
  // Pulse effect: grow and shrink
  with NodeZoomAnimation.Create(TreeAnimate1) do
  begin
    Shape := Node;
    FromZoom := 100;
    ToZoom := 150;
    Duration := 300;
  end;
  
  with NodeZoomAnimation.Create(TreeAnimate1) do
  begin
    Shape := Node;
    FromZoom := 150;
    ToZoom := 100;
    Duration := 300;
  end;
end;

​
Reveal Effect

procedure RevealNode(Node: TTreeNodeShape);
begin
  // Start invisible
  Node.Transparent := True;
  
  // Fade in
  with TTransparencyAnimation.Create(TreeAnimate1) do
  begin
    Shape := Node;
    FromTransparency := 100;
    ToTransparency := 0;
    Duration := 500;
  end;
end;

​
Smooth Transition

procedure TransitionNode(Node: TTreeNodeShape; NewX, NewY: Integer);
begin
  with TMovementAnimation.Create(TreeAnimate1) do
  begin
    Shape := Node;
    ToX := NewX;
    ToY := NewY;
    Duration := 800;
  end;
end;
