    • Method Detail

      • shouldHide

        protected boolean shouldHide​(Component comp,
                                     double angle,
                                     double scale)
        Overrides the normal layout method to determine if the object is offscreen and can therefore be ignored (giving a performance gain). In addition, it will adjust the alpha of the component based on its distance from 3'oclock (or 15:00 if you use a 24-hour compass)
        Overrides:
        shouldHide in class CaroselLayout
        Parameters:
        comp - The component to consider
        angle - Its position on the carousel.
        scale - The scale (applied to size) of the image, that is, how far from the observer is it
        Returns:
        True if it should be hidden, false if it should not
      • getCarouselRadius

        protected Dimension getCarouselRadius​(Container target,
                                              Insets insets,
                                              int width,
                                              int height,
                                              int widestComponent)
        Determines how "wide" the carousel should be drawn based on the side of the container the layout is laying out
        Overrides:
        getCarouselRadius in class CaroselLayout
        Parameters:
        target - The container the radius should be calculated for
        insets - Any insets of the container
        width - The width of the container
        height - The height of the container
        widestComponent - The widest component
        Returns:
        The size (in a bounding box) of the carousel
      • calculateCenter

        protected Point calculateCenter​(Insets insets,
                                        int width,
                                        int height,
                                        int widest)
        Determines the center of the carousel based on the dimensions of the container
        Overrides:
        calculateCenter in class CaroselLayout
        Parameters:
        insets - The container insets
        width - Width of the container
        height - The height of the container
        widest - width of the container
        Returns:
        A point representing the new center
      • setFrontMostComponent

        public void setFrontMostComponent​(Component component)
        Over-rides the normal setFrontMostComponent to move the selected component to 3 o'clock instead of 6 o'clock
        Overrides:
        setFrontMostComponent in class CaroselLayout
        Parameters:
        component - The component to move to the 'front'
