Apple Event Handlers Supplied by Client Applications

Showing or Hiding the Floating Input Window

Input methods that supply floating input windows for bottomline input may need to show or hide the input window at various times. The Show/Hide Input Window Apple event requests the client application to make the floating input window either visible or not visible, so that an input method can offer any of the above options.

Note

If your application is not displaying its own floating input window, you can ignore this Apple event.
