Properties of both the document and the viewer can be queried: + + * Does the document have content? + * Has it been modified? + * Is an overview (thumbnails or bookmarks) supported? + +``AbstractViewer`` provides protected methods for derived classes to create +actions and menus on the main window. In order to display these assets on the +main window, they are parented to it. ``AbstractViewer`` is responsible for +removing and destroying the UI assets it creates. It inherits from ``QObject`` +to implement signals and slots. + +The ``uiInitialized()`` signal is emitted after a viewer receives all necessary +information about UI assets on the main window. + +The ``printingEnabledChanged()`` signal is emitted when document printing is +either enabled or disabled. This happens after a new document was successfully +loaded, or, for example, all content was removed. + +The ``printStatusChanged`` signal notifies about changes in its progress after +starting the printing process. + +The ``documentLoaded()`` signal notifies the application that a document was +successfully loaded. |
