65 The %session Server launches and stops GUI (Graphical User Interface).
66 The %session can be active without GUI (It can contain one or more running studies)

72 exception GUIActive {} ;
73 //! This exception is raised when trying to stop the %session with running study.

105 This method can be used to send a message to the GUI from the standalone
107 Caution: this method can block the Session and the calling container
108 if it is called when container processes some request from the GUI
109 (mutual lock takes place).
110 In such a case it is recommended to use oneway method.

114 //! same as emitMessage but in a non blocking way
116 Emit a qt signal from the session GUI desktop window.
117 This method can be used to send a message to the GUI from the standalone
119 This method never blocks the Session and the calling container.
