Hi!
I am writing an application that periodically reads data from network sockets
(from Modbus enabled devices actually) and displays them in GTK+ application. I
read some tutorials about GTK threads and created a separate thread that
encompasses Modbus reads and updates to GTK labels:
You modify your label from a thread that is not the main/ui thread.
Gtk+ is not threadsafe (few exceptions). Use g_idle_add/ g_timeout_add/ and
friends (those are threadsafe) to implicitly serialize your ui
modifications into the gtk mainloop.
Do not use GDK_THREADS_ENTER/LEAVE foo unless you are
Is there any tutorial on them? I searched the Web and did not find any good
tutorial on GTK threads.

Hi!
Speaking of threading in Gtk, I'm using it quite extensively in my
application and never was really sure I was doing the right thing.
Here are the part in my codebase where I handle background jobs and
downloads:

The cairo patch is provisional and may need further work; basic problem is
that a quartz surface created for a window takes its device scale into
account on the Quartz (CGContext) side but the cairo side doesn't know about
it and treats it like a 1x-scaled surface. This was leading many
Hi,
I wonder if it would be possible to remove gtk's global variables?
I'd like to do something like:
GtkCtx *gtk_ctx = gtk_init(..);
GtkWindow *window = gtk_window_new(gtk_ctx, ...);
...
gtk_main_loop(gtk_ctx);
So in this way it would be possible to run many gtk main loop in
different threads

I am sure one can handle pretty much anything using g_main_context fun, but

Hi Emmanuele,
apps using X11 to draw directly should stop doing that, because this is not
1997 any more, and we have better drawing API.
Many many apps need a faster drawing API than Cairo in order to do high
frame rate animations. Interactive games is the most popular example.
I have

i think that quickplot and quickscope are not the same thing.
I found in your GIR file, it don't detect (for example) confi_new() as a
function of Confi object and it is not introspectable. Also, all functions
are free no related to any GObject. Then you haven't provided enough
information to detect namespace and its GObjects.

Hello!
I've got an application that was written rather long ago using GTK+ 2.20.1
and now I'm trying to launch it on a new system that has GTK+ 2.24.22
installed. The program compiles fine, without any warnings, opens a window
and hags forever refusing to draw anything. I use Cairo for drawing.
Thanks.
However, I just added one line in my gtkrc:
GtkTreeView::row_ending_details = 1
And that did it!
