Re: g_log_set_fatal_mask() not working for me.

Hi Richard,

This sounds similar to the problem Dino Aljević had in "Scrolled TreeView and size allocation warnings" in 
this list in September?

I can get the warning

"(treeview4:3830): Gtk-WARNING **: Allocating size to GtkWindow 0x843e188 without calling 
gtk_widget_get_preferred_width/height(). How does the code know the size to allocate?"

with the following code with GTK3.22.26 but I don't see the warning in GTK3.18.9. To get the warning expand 
the treeview until the list extends past the window boundry. I looked on Bugzilla but I didn't see it listed 
there. I am not great at finding things on Bugzilla so that doesn't mean it isn't there.

Do you have some test code to produce the GtkScrollbar warning you are seeing?

For the g_log_set_fatal_mask() and a runtime stop, try starting your code with 

G_DEBUG=fatal-warnings

It is a warning though. Something needs to be fixed but your program should run fine.
