30 * XML-configured GUI subsystem.
32 * This subsystem manages the graphical user interface for FlightGear.
33 * It creates a menubar from the XML configuration file in
34 * $FG_ROOT/gui/menubar.xml, then stores the configuration properties
35 * for XML-configured dialog boxes found in $FG_ROOT/gui/dialogs/. It
36 * can show or hide the menubar, and can display any dialog by name.
38 class NewGUI : public FGSubsystem
53 * Initialize the GUI subsystem.
58 * Reinitialize the GUI subsystem.

63 * Bind properties for the GUI subsystem.
65 * Currently, this method binds the properties for showing and
71 * Unbind properties for the GUI subsystem.

78 * Currently, this method is a no-op, because nothing the GUI
79 * subsystem does is time-dependent.

84 * Display a dialog box.
86 * At initialization time, the subsystem reads all of the XML
87 * configuration files from the directory $FG_ROOT/gui/dialogs/.
88 * The configuration for each dialog specifies a name, and this
89 * method invokes the dialog with the name specified (if it
92 * @param name The name of the dialog box.
93 * @return true if the dialog exists, false otherwise.
