Basic class of the GENIUS library, it is the base class used to represent all the GENIUS widgets. All classes of widgets inherit of class GComponent. It allows:
- Defining basic mechanisms of display,
- Handling of names, units, comments, and data groups to save / load data from configuration files,
- Creating and updating widgets hierarchy and identification of the display panel,
- Activating / deactivating the widget,
- Commanding the focus, in order to navigate from a widget to another widget using keys «Enter» and «Tab»,
- Defining a protocol that allows to determine if the value represented by a widget is modified with respect to last values saved in the file,
- Handling widgets identifiers.
