  public Animator()

Constructs a default Animator. The animator defaults to a 500 millisecond delay, and loops forever.

  public void setDelay(int i)

Sets the delay between animation frames.

Parameters:

i - animation delay, in milliseconds

See Also:

getDelay

  public int getDelay()

Returns the current delay between animation frames.

Returns:

current animation delay, in milliseconds

See Also:

setDelay

  public void setNumLoops(int i)

Sets the number of loops to perform when displaying the animation set.

Parameters:

i - loop count

See Also:

getNumLoops

  public int getNumLoops()

Returns the current animation set loop count.

Returns:

loop count

See Also:

setNumLoops

  public void setRepeatMode(boolean b)

Sets the repeat mode setting.

Parameters:

b - repeat mode, repeats if true

See Also:

getRepeatMode

  public boolean getRepeatMode()

Returns the current repeat mode setting.

Returns:

current repeat mode setting, true if repeat forever

See Also:

setRepeatMode

  public synchronized void addImage(URL url)

Adds an image to the animation set.

Parameters:

url - URL of the image to add

  public synchronized void setImageList(URL list[])

Sets the image list. Images in this list are displayed in sequence to form the animation.

Parameters:

list - array of image URLs

See Also:

getImageList

  public synchronized URL[] getImageList()

Returns the image list.

Returns:

URL list of images

See Also:

setImageList

  public void setClearFrame(boolean b)

Sets whether or not the animation frame area is cleared between each frame.

Parameters:

b - if true, the frame area is cleared between each animation frame; if false, the frame area is not cleared.

See Also:

getClearFrame

  public boolean getClearFrame()

Gets the current clear frame setting.

Returns:

boolean - if true, the frame area is cleared between each animation frame; if false, the frame area is not cleared.

See Also:

setClearFrame

  public void startAnimation()

Starts the animation.

See Also:

stopAnimation

  public void stopAnimation()

Stops the animation.

See Also:

startAnimation

  public void setPreviewMode(boolean f)

Sets the preview mode flag. This flag is used by Visual Cafe to determine if this component should be run during design time.

Parameters:

f - new preview mode

See Also:

getPreviewMode

  public boolean getPreviewMode()

Gets the preview mode flag. This flag is used by Visual Cafe to determine if this component should be run during design time.

Parameters:

f - new preview mode

See Also:

setPreviewMode

  public synchronized void run()

Body of Animation Thread. This method is called by the Java Virtual Machine in response to a call to the start method of this object.

  public synchronized void paint(Graphics g)

Paints this component using the given graphics context. This is a standard Java AWT method which typically gets called by the AWT to handle painting this component. It paints this component using the given graphics context. The graphics context clipping region is set to the bounding rectangle of this component and its <0,0> coordinate is this component's top-left corner.

Parameters:

g - the graphics context used for painting

Overrides:

paint in class Canvas

See Also:

repaint, update

  public void update(Graphics g)

Handles redrawing of this component on the screen. This is a standard Java AWT method which gets called by the Java AWT (repaint()) to handle repainting this component on the screen. The graphics context clipping region is set to the bounding rectangle of this component and its <0,0> coordinate is this component's top-left corner. Typically this method paints the background color to clear the component's drawing space, sets graphics context to be the foreground color, and then calls paint() to draw the component. It is overridden here to make clearing the background before painting optional. If the clearFrame flag is true the background will be erased before painting begins.

Parameters:

g - the graphics context

Overrides:

update in class Component

See Also:

repaint, paint

  public Dimension preferredSize()

Returns the recommended dimensions to properly display this component. This is a standard Java AWT method which gets called to determine the recommended size of this component.

Returns:

If no images have been loaded, a dimension of 10 by 10 is returned. If one or more images have been loaded, the largest height and the largest width of any image is returned.

Overrides:

preferredSize in class Component

See Also:

minimumSize

  public Dimension minimumSize()

Returns the minimum dimensions to properly display this component. This is a standard Java AWT method which gets called to determine the minimum size of this component.

Returns:

If no images have been loaded, a dimension of 10 by 10 is returned. If one or more images have been loaded, the largest height and the largest width of any image is returned.

Overrides:

minimumSize in class Component

See Also:

preferredSize
