  \brief Provides access to input methods in the compositor.

  The \c QtTextInputMethodManager corresponds to the \c qt-text-input-method-manager interface
  in the \c qt-text-input-method-unstable-v1 extension protocol. It is specifically designed
  to be used with a Qt-based input method, such as Qt Virtual Keyboard.

  Instantiating this as child of a \l WaylandCompositor adds it to the list of interfaces available
  to the client. If a client binds to it, then it will be used to communciate text input to
  that client.
