[gtkada] GtkAda and tasking

[Jean-Pierre Rosen]

> Could you please explain what is "not perfectly clear" in the
documentation ?
Here are the relevant paragraphs:

<<When Glib is initialized to be task-safe, GtkAda is task aware. There is a
single global lock that you must acquire with Gdk.Threads.Enter before
making any Gdk/Gtk call, and release with Gdk.Threads.Leave afterwards. >>
If it is really a lock, it would mean that I cannot have one task managing
one window, with another one managine another window. If that's the case, I
would describe it as a "sequential" component, not a "concurrent" one...

<<Beware that the GtkAda main loop (Gtk.Main.Main) can only be be run inside
one specific tasks. In other words, you cannot call Gtk.Main.Main from a
different task that the one that started the outer level main loop. >>
This is what I find particularly unclear. What is the "outer level main
loop" if it is not Gtk.Main.Main ? Moreover, I tried to initialize the
system (Gtk.Main.Init, Gtk_New) from the main task, then call Gtk.Main.Main
from another one. This did not seem to contradict the previous paragraph,
but it blocked the system.

for

I'd love to. The question is how to do it (see my other message).
