System [00 00 00 00 00 00 00 00 04 00 00 00 00 00 00 00] 1.0.3300.0 1.0.5000.0 2.0.0.0 4.0.0.0 Gtk# is thread aware, but not thread safe; See the <link location="node:gtk-sharp/programming/threads">Gtk# Thread Programming</link> for details. System.EventArgs This class provides data for the event. The property returns a structure identifying the time when the timer was signalled. Provides data for the event. Property 1.0.5000.0 2.0.0.0 4.0.0.0 System.DateTime To be added: an object of type 'DateTime' The event is raised on a thread, so the event-handling method might run on one thread at the same time that a call to the method runs on another thread. This might result in the event being raised after the method is called. This race condition cannot be prevented simply by comparing the property with the time when the method is called, because the event-handling method might already be executing when the method is called, or might begin executing between the moment when the method is called and the moment when the stop time is saved. If it is critical to prevent the thread that calls the method from proceeding while the event-handling method is still executing, use a more robust synchronization mechanism such as the class or the method. Code that uses the method can be found in the example for the method. Gets the time the event was raised.
