gtk-sharp 2.0.0.0 Gtk# is thread aware, but not thread safe; See the Gtk# Thread Programming for details. Multi-threaded integration with Gtk support. The ThreadNotify class is used to invoke methods in the Gtk+ thread. Since Gtk is not a thread-safe toolkit, only a single thread at a time might be making calls into Gtk. Typically applications will be executing the main Gtk+ main loop and when threads are done processing work, they invoke to invoke a method on the main Gtk+ thread. using Gtk; class Demo { static ThreadNotify notify; static void Main () { Application.Init (); notify = new ThreadNotify (new ReadyEvent (ready)); Application.Run (); } static void ready () { // Update the GUI with computation values. } static void ThreadRoutine () { LargeComputation (); notify.WakeupMain (); } static void LargeComputation () { // lots of processing here } } System.Object System.IDisposable Method System.Void Wakeup the main thread, and invoke delegate. This methods wakes up the Gtk+ main thread and executes the delegate that was specified at construction time in the Gtk+ thread. Constructor ThreadNotify constructor A ReadyEvent delegate. The method referenced by the delegate will be invoked on the Gtk+ mainloop whenever any thread invokes the method. Method System.Void To be added Method System.Void To be added a
