Im trying to manipulate an image using system.drawing in GTk#.I want the UI to update the image on screen as soon as the user updates a textbox.To implement this i tried using the background worker from winforms,it worked but when the textbox is updated at a higher speed the application becomes stuck with no error.
So i took a look at multithreading in GTK here http://www.mono-project.com/docs/gui/gtksharp/responsive-applications/ and created a thread . void textboxchanged() { Thread thr = new Thread (new ThreadStart (ThreadRoutine)); thr.Start (); } static void ThreadRoutine () { LargeComputation (); } static void LargeComputation () { image=new Bitmap(backupimage); //Long image processing } It works poorly than the background worker throws up object currently in use elsewhere error here image=new Bitmap(backupimage); when the speed of entry in textbox is even a little fast.What im i doing wrong ? -- View this message in context: http://mono.1490590.n4.nabble.com/Accessing-System-Drawing-Bitmap-from-GTK-Thread-throws-Object-Currently-in-use-elsewhere-exception-tp4665133.html Sent from the Mono - Gtk# mailing list archive at Nabble.com. _______________________________________________ Gtk-sharp-list maillist - Gtk-sharp-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/gtk-sharp-list
