Message definition (Develop an simple input method )
== Key event handling ==
== Key event handling ==
The most common use case is to call filterAndAccept() for all the key event that you intends to handle. Also, for most input method, key release is not relevant and should be pass-through to application. To make input method engine to work with any user input, be sure to consider all the possible key event that may be typed by user. For example, a common error is forgetting to block certain irrelevant key in composing mode and leaking the key into the application. Also, be careful for key event with modifier, you may want to pass through such key to make application specific hotkey still accessible even when user is composing.
