39  * @brief An abstract view that displays a GlMainWidget as its central widget.
40  *
41  * The GlMainView subclasses ViewWidget and always uses a GlMainWidget as the central widget of the panel. It also adds the following features:
42  * @list
43  * @li An overview of the scene that can be toggled on or off.
44  * @li Some configuration widgets that modify the rendering parameters.
45  * @li A quick access bar widget that allows the user to quickly modify some of the most used rendering parameters and graph properties (nodes color, edges display, etc)
46  * @li The possibility to make snapshots of the current scene
47  * @endlist
48  *
49  * Subclassing GlMainView means you will only want to display graphs in a single GlMainWidget. Switching the central widget can only be achieved from the ViewWidget class.
50  *
51  * @warning It is strongly unadvised to re-implement methods already implemented into tlp::View or tlp::ViewWidget. If you have to add custom behavior to those method, make sure to call the upper-class methods first:
52  @code
53  void MyView::setupWidget() { // Where MyView is a subclass of tlp::GlMainView
54  GlMainView::setupWidget(); // call this first
55  // insert custom behavior here
56  }
57  @endcode
58 
59  * @see tlp::ViewWidget
