-
- \brief Provides a handwriting panel add-on for the virtual keyboard UI.
- \ingroup qtvirtualkeyboard-qml
-
- 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 instance.
-
- The panel is set into operation by setting the \l {HandwritingInputPanel::}{available}
- property to \c true. When the panel is in operation, the keyboard remains hidden
- when the input focus is set. When \c available is \c true, handwriting input is
- activated by setting the \l {HandwritingInputPanel::}{active} property to \c 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 \l {HandwritingInputPanel::}{active} property), and double-click toggles
- the visibility of the keyboard (changes the \l {HandwritingInputPanel::}{available} property).
-
- 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 must be set to the existing input panel instance.

- property var inputPanel
-
- /*! This property controls the availability status of the handwriting input method.
-
- Setting the property to \c true prepares the handwriting input method and inhibits
- the display of keyboard.
- */

-
- /*! This property controls the active status of the handwriting input method.
-
- Setting the property to \c 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.
