[Gtk-sharp-list] Table layout and cross-thread calling

Tue Mar 13 08:25:15 EDT 2007

I learn to use Threading in Gtk, and it is really easy:

If it help, read it from my project svn page:

This is where i call the thread start
http://gcomandos.svn.sourceforge.net/viewvc/gcomandos/trunk/gComandos/gComandos/ui/windows/CopyFile.cs?revision=81&view=markup

This is the method called:
http://gcomandos.svn.sourceforge.net/viewvc/gcomandos/trunk/gComandos/gComandos/fs/XferOperation.cs?revision=68&view=markup

I use an object to get all the info about the second thread, it has a 
constructor with all the info needed in the second thread (you cannot pass 
parameters to new ThreadStart(method)). I pass callback to return to 
previous thread, and i use Gtk.Application.Invoke to change the Gtk Thread.

You can even see a code with Monitor and Lock too:
http://gcomandos.svn.sourceforge.net/viewvc/gcomandos/trunk/gComandos/gComandos/ui/windows/DeleteFile.cs?revision=81&view=markup

I hope it helps.
