  • Method Details

    • paint

      boolean paint(Graphics g, Shape s)
      handles the paint, then returns whether to run the default painting or not.
      NOTE: is only meant to be called for "low-level" views without children.
      Parameters:
      g - graphics
      s - allocated shape to paint in
      Returns:
      true if painting can continue, false if this view should not actually paint itself

    • clone

      Object clone() throws CloneNotSupportedException
      Creates and Returns a copy of this object.
      Returns:
      a copy of this object
      Throws:
      CloneNotSupportedException - Thrown if clone() is not supported by the implementation
      Since:
      1.05

    • wasPainted

      default boolean wasPainted()
      Returns whether a view was already painted and thus should not be painted again. This call does not affect the 'painted' state as paint(Graphics, Shape) does.

      1.12

    • setAllocation

      default void setAllocation(Rectangle allocation)
      An alternative way to store the allocation of the parent view without calling paint(Graphics, Shape).
      Parameters:
      allocation - the allocation relative to the top left of the root view
      Since:
      1.12

    • markAsPainted

      default void markAsPainted()
      Marks a view as already painted. Has the same effect as calling paint(Graphics, Shape) with a clip where the view is visible.
      Since:
      1.12

    • reset

      default void reset()
      Resets the state of the painter to 'not yet painted'
