详细描述

The HandwritingInputPanel is an add-on component for the InputPanel , which enables full-screen handwriting input for the application.

HandwritingInputPanel is designed to be anchored full screen alongside the InputPanel . The operating principle is that when the handwriting panel is "available", the InputPanel is invisible. This functionality is built-in, and requires no more than a reference to the InputPanel 实例。

The panel is set into operation by setting the available 特性到 true . When the panel is in operation, the keyboard remains hidden when the input focus is set. When available is true , handwriting input is activated by setting the active 特性到 true .

The user interface, which provides controls for handwriting mode and the visibility of the keyboard, is application-specific. One suggested implementation is to use a floating button on the handwriting panel, where single click toggles the handwriting mode (changes the active property), and double-click toggles the visibility of the keyboard (changes the available 特性)。

HandwritingInputPanel also provides a word candidate popup which allows the user to select an alternative word candidate from the list of suggestions generated by the handwriting input method.
