public class FlipTransition extends Transition

A Transitions that flips between 2 components/forms using perspective transform where available.

Notice that this looks rather different on devices as perspective transform is available there but isn't on the simulator.

  • Constructor Details

    • FlipTransition

      public FlipTransition()
      Creates a Flip Transition

    • FlipTransition

      public FlipTransition(int bgColor)

      Creates a Flip Transition

      Parameters
      • bgColor: @param bgColor the color to paint in the background when the transition paints, use -1 to not paint a background color

    • FlipTransition

      public FlipTransition(int bgColor, int duration)

      Creates a Flip Transition

      Parameters

      • bgColor: @param bgColor the color to paint in the background when the transition paints, use -1 to not paint a background color

      • duration: the duration of the transition

  • Method Details

    • initTransition

      public void initTransition()
      Description copied from class: Transition
      Callback thats invoked before a transition begins, the source form may be null for the first form in the application.
      Overrides:
      initTransition in class Transition

    • animate

      public boolean animate()
      Description copied from class: Transition

      Allows the animation to reduce "repaint" calls when it returns false. It is called once for every frame. Frames are defined by the com.codename1.ui.Display class.

      Returns

      true if a repaint is desired or false if no repaint is necessary

      Specified by:
      animate in interface Animation
      Specified by:
      animate in class Transition

    • paint

      public void paint(Graphics g)
      Description copied from class: Transition

      Draws the animation, within a component the standard paint method would be invoked since it bares the exact same signature.

      Parameters
      • g: graphics context
      Specified by:
      paint in interface Animation
      Specified by:
      paint in class Transition

    • cleanup

      public void cleanup()
      Description copied from class: Transition
      Optional operation to cleanup the garbage left over by a running transition
      Overrides:
      cleanup in class Transition

    • getDuration

      public int getDuration()

      The duration for the flip transition

      Returns

      the duration

    • setDuration

      public void setDuration(int duration)

      The duration for the flip transition

      Parameters
      • duration: the duration to set

    • getBgColor

      public int getBgColor()

      The background color that is painted behind the flipping effect or -1 to use the paintBackgrounds method instead

      Returns

      the bgColor

    • setBgColor

      public void setBgColor(int bgColor)

      The background color that is painted behind the flipping effect or -1 to use the paintBackgrounds method instead

      Parameters
      • bgColor: the bgColor to set

    • copy

      public Transition copy(boolean reverse)

      Create a copy of the transition, usually the transition used is a copy.

      Parameters
      • reverse: @param reverse creates a new transition instance with "reverse" behavior useful for signifying "back" operations
      Returns

      new transition instance

      Parameters
      • reverse:

      Create a copy of the transition, usually the transition used is a copy.

      Parameters

      Returns

      new transition instance

      Returns

      Create a copy of the transition, usually the transition used is a copy.

      Parameters
      • reverse: @param reverse creates a new transition instance with "reverse" behavior useful for signifying "back" operations
      Returns

      new transition instance

      Overrides:
      copy in class Transition
