Re: Glib::Thread && Gtk::Window

["Nickolai Dobrynin" <ndobrynin gmail com>]

Alexander,

OK, let's go one step at a time.   Are you confident you do
all your GUI work in the same thread (the most common approach) OR are
you confident you synchronize each and every GTK call you make (this
can be both very complex and inefficient)?  The following line in
your original post sounds strange to me: "I use Glib::Thread to create
threads for new window".  I hope you aren't trying to run every
new window in a different thread.  Please clarify.

In general, there is no conceptual difference between the way you would
handle one GTK window and multiple ones.  All you do is allocate
each on the heap, keep the pointers around, and access them as needed.

Apologies if I sound too basic, but that seems to be the nature of the problem you are having.


Regards,

Nickolai

Hello, Nickolai.

You know, I try to replace my window with Gtk::Window(). But there is
the same problem. Main window work OK, but child window is not
responding!!!
Maybe I do something wrong?
