      • removeLayoutComponent

        public void removeLayoutComponent​(Component component)
        Removes the specified component from our knowledge.
        Specified by:
        removeLayoutComponent in interface LayoutManager
        Parameters:
        component - the component to be removed
      • addLayoutComponent

        public void addLayoutComponent​(Component comp,
                                       Object constraints)
        Adds the specified component to the layout, using the specified constraint object.
        Specified by:
        addLayoutComponent in interface LayoutManager2
        Parameters:
        comp - the component to be added
        constraints - where/how the component is added to the layout.
      • getLayoutAlignmentX

        public float getLayoutAlignmentX​(Container target)
        Returns the alignment along the x axis. This specifies how the component would like to be aligned relative to other components. The value should be a number between 0 and 1 where 0 represents alignment along the origin, 1 is aligned the furthest away from the origin, 0.5 is centered, etc.
        Specified by:
        getLayoutAlignmentX in interface LayoutManager2
        Parameters:
        target - the target container
        Returns:
        the x-axis alignment preference
      • getLayoutAlignmentY

        public float getLayoutAlignmentY​(Container target)
        Returns the alignment along the y axis. This specifies how the component would like to be aligned relative to other components. The value should be a number between 0 and 1 where 0 represents alignment along the origin, 1 is aligned the furthest away from the origin, 0.5 is centered, etc.
        Specified by:
        getLayoutAlignmentY in interface LayoutManager2
        Parameters:
        target - the target container
        Returns:
        the y-axis alignment preference
      • invalidateLayout

        public void invalidateLayout​(Container c)
        Does nothing. If the developer really wants to change the size of one of the views JSplitPane.resetToPreferredSizes should be messaged.
        Specified by:
        invalidateLayout in interface LayoutManager2
        Parameters:
        c - the target container
      • resetToPreferredSizes

        public void resetToPreferredSizes()
        Marks the receiver so that the next time this instance is laid out it'll ask for the preferred sizes.
      • resetSizeAt

        protected void resetSizeAt​(int index)
        Resets the size of the Component at the passed in location.
        Parameters:
        index - the index of a component
      • setSizes

        protected void setSizes​(int[] newSizes)
        Sets the sizes to newSizes.
        Parameters:
        newSizes - the new sizes
      • getSizes

        protected int[] getSizes()
        Returns the sizes of the components.
        Returns:
        the sizes of the components
      • getPreferredSizeOfComponent

        protected int getPreferredSizeOfComponent​(Component c)
        Returns the width of the passed in Components preferred size.
        Parameters:
        c - a component
        Returns:
        the preferred width of the component

        protected int getSizeOfComponent​(Component c)
        Returns the width of the passed in component.
        Parameters:
        c - a component
        Returns:
        the width of the component
      • getAvailableSize

        protected int getAvailableSize​(Dimension containerSize,
                                       Insets insets)
        Returns the available width based on the container size and Insets.

      • getInitialLocation

        protected int getInitialLocation​(Insets insets)
        Returns the left inset, unless the Insets are null in which case 0 is returned.

        insets - the insets
        Returns:
        the left inset
      • setComponentToSize

        protected void setComponentToSize​(Component c,
                                          int size,
                                          int location,
