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

Overriding: java.awt.Container

Adds the specified component to this container at the specified index. This method also notifies the layout manager to add the component to this container's layout using the specified constraints object via the addLayoutComponent method.

The constraints are defined by the particular layout manager being used. For example, the BorderLayout class defines five constraints: BorderLayout.NORTH, BorderLayout.SOUTH, BorderLayout.EAST, BorderLayout.WEST, and BorderLayout.CENTER.

The GridBagLayout class requires a GridBagConstraints object. Failure to pass the correct type of constraints object results in an IllegalArgumentException.

If the current layout manager implements LayoutManager2, then LayoutManager2.addLayoutComponent(Component,Object) is invoked on it. If the current layout manager does not implement LayoutManager2, and constraints is a String, then LayoutManager.addLayoutComponent(String,Component) is invoked on it.

If the component is not an ancestor of this container and has a non-null parent, it is removed from its current parent before it is added to this container.

This is the method to override if a program needs to track every add request to a container as all other add methods defer to this one. An overriding method should usually include a call to the superclass's version of the method:

super.addImpl(comp, constraints, index)

This method changes layout-related information, and therefore, invalidates the component hierarchy. If the container has already been displayed, the hierarchy must be validated thereafter in order to display the added component.

Parameters:

comp     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

@BeanProperty(bound=false)
public AccessibleContext getAccessibleContext ()

Implementing: javax.accessibility.Accessible

Gets the AccessibleContext associated with this JLayeredPane. For layered panes, the AccessibleContext takes the form of an AccessibleJLayeredPane. A new AccessibleJLayeredPane instance is created if necessary.

Returns: an AccessibleJLayeredPane that serves as the AccessibleContext of this JLayeredPane

@BeanProperty(bound=false)
public boolean isOptimizedDrawingEnabled ()

Overriding: javax.swing.JComponent

Returns false if components in the pane can overlap, which makes optimized drawing impossible. Otherwise, returns true.

Returns: false if components can overlap, else true

public void paint (Graphics g)

Overriding: javax.swing.JComponent

Paints this JLayeredPane within the specified graphics context.

Parameters:

g the Graphics context within which to paint

protected String paramString ()

Overriding: javax.swing.JComponent

Returns a string representation of this JLayeredPane. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not be null.

Returns: a string representation of this JLayeredPane.

public void remove (int index)

Overriding: java.awt.Container

Remove the indexed component from this pane. This is the absolute index, ignoring layers.

Parameters:

index an int specifying the component to remove

`comp`		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
