java.lang.Object
   java.awt.im.InputContext
      sun.awt.im.InputContext

All known Subclasses:   sun.awt.im.InputMethodContext,
InputContext
public class InputContext extends java.awt.im.InputContext (Code)
An InputContext object manages the communication between text editing components and input methods. It dispatches events between them, and forwards requests for information from the input method to the text editing component.

By default, one InputContext instance is created per Window instance, and this input context is shared by all components within the window's container hierarchy. However, this means that only one text input operation is possible at any one time within a window, and that the text needs to be committed when moving the focus from one text component to another. If this is not desired, text components can create their own input context instances.

Constructor Detail
InputContext
protected InputContext()(Code)
Constructs an InputContext.




Method Detail
activate
synchronized void activate(Component client)(Code)
Activates input context for the given component. If the input context previously was active for a different component and there is uncommitted text for that component, the text is committed. Called by AWT when the keyboard focus moves to the component.
Parameters:
  client - The client component into which text is entered.



deactivate
synchronized void deactivate(Component client)(Code)
Deactivates input context for the given component. Called by AWT when the keyboard focus moves away from the component.
Parameters:
  target - The component into which text was entered.



dispatchEvent
public synchronized void dispatchEvent(AWTEvent event)(Code)
Dispatches an event to the active input method. Called by AWT.
Parameters:
  event - The event



dispose
public void dispose()(Code)
Disposes of the input context and release the resources used by it. Called by AWT.



getClientComponent
Component getClientComponent()(Code)
Returns the client component.



getInputMethod
InputMethod getInputMethod()(Code)



isCompositionEnabled
public boolean isCompositionEnabled()(Code)



removeNotify
public void removeNotify(Component client)(Code)



selectInputMethod
public boolean selectInputMethod(Locale locale)(Code)



setCompositionEnabled
public void setCompositionEnabled(boolean enable)(Code)
