Method Detail

dispatchInputMethodEvent

public void dispatchInputMethodEvent(int id,
                                     AttributedCharacterIterator text,
                                     int committedCharacterCount,
                                     TextHitInfo caret,
                                     TextHitInfo visiblePosition)
Creates an input method event from the arguments given and dispatches it to the client component. For arguments, see InputMethodEvent.InputMethodEvent(java.awt.Component, int, java.text.AttributedCharacterIterator, int, java.awt.font.TextHitInfo, java.awt.font.TextHitInfo).

createInputMethodWindow

public Window createInputMethodWindow(String title,
                                      boolean attachToInputContext)
Creates a top-level window for use by the input method. The intended behavior of this window is: However, the actual behavior with respect to these three items is platform dependent.

The title may or may not be displayed, depending on the actual type of window created.

If attachToInputContext is true, the new window will share the input context that corresponds to this input method context, so that events for components in the window are automatically dispatched to the input method. Also, when the window is opened using setVisible(true), the input context will prevent deactivate and activate calls to the input method that might otherwise be caused.

Parameters:
title - the title to be displayed in the window's title bar, if there is such a title bar. A null value is treated as an empty string, "".
attachToInputContext - whether this window should share the input context that corresponds to this input method context
Returns:
a window with special characteristics for use by input methods

enableClientWindowNotification

public void enableClientWindowNotification(InputMethod inputMethod,
                                           boolean enable)
Enables or disables notification of the current client window's location and state for the specified input method. When notification is enabled, the input method's notifyClientWindowChange method is called as described in that method's specification. Notification is automatically disabled when the input method is disposed.
Parameters:
inputMethod - the input method for which notifications are enabled or disabled
enable - true to enable, false to disable
