  • invalidate

    public void invalidate()

    Overridden to avoid propagating a invalidate up the tree when the cell renderer child is configured.

    Overrides:

    invalidate in class Container

    See Also:

    Container.validate(), Container.layout(), LayoutManager2

  • paint

    public void paint(Graphics g)

    Shouldn't be called.

    Overrides:

    paint in class Container

    Parameters:

    g - the specified Graphics window

    See Also:

    Component.update(Graphics)

  • update

    public void update(Graphics g)

    Shouldn't be called.

    Overrides:

    update in class Container

    Parameters:

    g - the specified Graphics window

    See Also:

    Component.update(Graphics)

  • addImpl

    protected void addImpl(Component x,
     Object constraints,
     int index)

    If the specified component is already a child of this then we don't bother doing anything - stacking order doesn't matter for cell renderer components (CellRendererPane doesn't paint anyway).<

    Overrides:

    addImpl in class Container

    Parameters:

    x - the component to be added

    constraints - an object expressing layout constraints for this component

    index - the position in the container's list at which to insert the component, where -1 means append to the end

    See Also:

    Container.add(Component), Container.add(Component, int), Container.add(Component, java.lang.Object), Container.invalidate(), LayoutManager, LayoutManager2

  • paintComponent

    public void paintComponent(Graphics g,
     Component c,
     Container p,
     int x,
     int y,
     int w,
     int h,
     boolean shouldValidate)

    Paint a cell renderer component c on graphics object g. Before the component is drawn it's reparented to this (if that's necessary), it's bounds are set to w,h and the graphics object is (effectively) translated to x,y. If it's a JComponent, double buffering is temporarily turned off. After the component is painted it's bounds are reset to -w, -h, 0, 0 so that, if it's the last renderer component painted, it will not start consuming input. The Container p is the component we're actually drawing on, typically it's equal to this.getParent(). If shouldValidate is true the component c will be validated before painted.

  • paintComponent

    public void paintComponent(Graphics g,
     Component c,
     Container p,
     int x,
     int y,
     int w,
     int h)

    Calls this.paintComponent(g, c, p, x, y, w, h, false).

  • paintComponent

    public void paintComponent(Graphics g,
     Component c,
     Container p,
     Rectangle r)

    Calls this.paintComponent() with the rectangles x,y,width,height fields.

  • getAccessibleContext

    public AccessibleContext getAccessibleContext()

    Gets the AccessibleContext associated with this CellRendererPane. For CellRendererPanes, the AccessibleContext takes the form of an AccessibleCellRendererPane. A new AccessibleCellRendererPane instance is created if necessary.

    Specified by:

    getAccessibleContext in interface Accessible

    Overrides:

    getAccessibleContext in class Component

    Returns:

    an AccessibleCellRendererPane that serves as the AccessibleContext of this CellRendererPane
