Hi AlannY, I'm new to this mail thread but I think that I know what your issue is. Basically, GTK/GDK is not designed to be called from multiple at the same time. Doing so causes all kinds of strange issues such as the ones that you are seeing. There are many ways to get around this issue but reading the information on http://library.gnome.org/devel/gdk/stable/gdk-Threads.html is a great start.
In general, I find it best never to make GTK/GDK calls from any thread other than the main thread, although it is possible. As stated earlier, I'm new to this mail list so if anyone would like to correct me then please go ahead. Hope that helps, Michael On 15/10/2007, AlannY <[EMAIL PROTECTED]> wrote: > AlannY wrote: > > Hi there. > > > > I have trouble in my program. > > > > First of all, I'm using latest GTK and got many assertion in console > > when using GtkTextBuffer. > > > > Second.
