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.
This property controls the active status of the handwriting input method.
Setting the property to
true
activates the handwriting input method. When the handwriting input method is active, all touch input is captured by the handwriting input panel and redirected to input engine for processing.
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.
