- extends InputMap
A ComponentInputMap is an InputMap associated with a particular JComponent. The component is automatically notified whenever the ComponentInputMap changes. ComponentInputMaps are used for WHEN_IN_FOCUSED_WINDOW bindings.
Constructor Summary
ComponentInputMap(JComponent component)
Creates a ComponentInputMap associated with the specified component.

Constructor Detail
ComponentInputMap
public ComponentInputMap(JComponent component)
- Creates a ComponentInputMap associated with the specified component.
- Parameters:
- component - a non-null JComponent
- Throws:
- IllegalArgumentException - if component is null
Method Detail
setParent
public void setParent(InputMap map)
- Sets the parent, which must be a ComponentInputMap associated with the same component as this ComponentInputMap.
- Overrides:
- setParent in class InputMap
- Parameters:
- map - a ComponentInputMap
- Throws:
- IllegalArgumentException - if map is not a ComponentInputMap or is not associated with the same component
getComponent
public JComponent getComponent()
- Returns the component the InputMap was created for.
put
public void put(KeyStroke keyStroke, Object actionMapKey)
- Adds a binding for keyStroke to actionMapKey. If actionMapKey is null, this removes the current binding for keyStroke.
- Overrides:
- put in class InputMap
remove
public void remove(KeyStroke key)
- Removes the binding for key from this object.
- Overrides:
- remove in class InputMap
clear
public void clear()
