installUI
public void installUI(JComponent c)
Description copied from class:ComponentUI
Configures the specified component appropriately for the look and feel. This method is invoked when theComponentUI
instance is being installed as the UI delegate on the specified component. This method should completely configure the component for the look and feel, including the following:- Install default property values for color, fonts, borders, icons, opacity, etc. on the component. Whenever possible, property values initialized by the client program should not be overridden.
- Install a
LayoutManager
on the component if necessary. - Create/add any required sub-components to the component.
- Create/install event listeners on the component.
- Create/install a
PropertyChangeListener
on the component in order to detect and respond to component property changes appropriately. - Install keyboard UI (mnemonics, traversal, etc.) on the component.
- Initialize any appropriate instance data.
- Overrides:
installUI
in classBasicSliderUI
- Parameters:
c
- the component where this UI delegate is being installed- See Also:
