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.

available : bool |
This property controls the availability status of the handwriting input method.
Setting the property to
true
prepares the handwriting input method and inhibits the display of keyboard.
inputPanel : var |
A reference to the input panel instance.
