Constructor Details

MultiPanelUI

public MultiPanelUI()
Constructs a MultiPanelUI.

Method Details

getUIs

public ComponentUI[] getUIs()
Returns the list of UIs associated with this multiplexing UI. This allows processing of the UIs by an application aware of multiplexing UIs on components.
Returns:
an array of the UI delegates

contains

public boolean contains(JComponent a, int b, int c)
Invokes the contains method on each UI handled by this object.
Overrides:
contains in class ComponentUI
Parameters:
a - the component where the x,y location is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
b - the x coordinate of the point
c - the y coordinate of the point
Returns:
the value obtained from the first UI, which is the UI obtained from the default LookAndFeel

update

public void update(Graphics a, JComponent b)
Invokes the update method on each UI handled by this object.
Overrides:
update in class ComponentUI
Parameters:
a - the Graphics context in which to paint

Parameters:
a - the component to create the UI for
Returns:
the UI delegate created

installUI

public void installUI(JComponent a)
Invokes the installUI method on each UI handled by this object.
