Re: g_spawn_async_with_pipes

Running echo output echo_out directly into lilypond's input echo_out as if they may share echo_out. I will need to test/hack this. I hate hacking. I wish we had more examples here in linux land! I just thought it would be more efficient and quicker to send data directly to lilypond instead of a file location. Since you're already using g_spawn_async_with_pipes(), why don't you simply execute /usr/bin/lilypond --output=scale.png - and then feed the lilyponds stdin through obtained file descriptor that g_spawn...() gives you? Cheers, Tadej Hi Tadej, Lilypond was very fussy with the stdin of g_spawn_async_with_pipes(). It didn't like it. In the end I just did the temp.ly file. It works well. It would be an interesting exercise if one of us on this list actually figured out how to pipe the output of one application to the stdin of another application using g_spawn_async_with_pipes(). Lilypond was very fussy with this. I would have to write some Scheme program to do this. I am 50 years old. I don't want to learn another syntax! Thanks for coaching me through the pipes!

Re: gtk3: behavior of gtk_widget_set_size_request

This works as expected in gtk2, but in gtk3 the treeview's window is much narrower (doesn't look like 120), and its width doesn't respond even if I double the request. Am I missing some change in the widget-sizing code? Yes that has changed, setting the size request now only effects the widgets requested size. We added gtk_scrolled_window_set_min_content_width() specifically for your purposes. OK, got it, thanks.

gtk3 migrating document and drawing
It seems that the section of the gtk-migrating-2-to-3 doc as distributed with gtk 3.0.0 is not up to date with the state of the drawing code in the release. For example, it still talks about using pixmaps in the replacement code sections. This is an area where it would be very helpful to have up-to-date and precise documentation.

gtk3: FileChooser schema not found
I have glib 2.28.0 installed, along with gtk 2.24.0 and gtk 3.0.0. Calls to the FileChooser in my app work as expected in 2.24, but in 3.0.0 they produce: GLib-GIO-ERROR **: Settings schema 'org.gtk.Settings.FileChooser' is not installed and the program aborts. The file org.gtk.Settings.FileChooser.gschema.xml is installed in $prefix/share/glib-2.0/schemas (2133 bytes). -- Allin Cottrell Department of Economics Wake Forest University ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Using GSocket in a GTK application
Hi all, I'm using GSocket in a GTK application in non-blocking mode. Once the connection is done, I'm creating a source for the main event loop: my_source = g_socket_create_source(my_socket, my_events, NULL); How do we specify a callback? Should I use g_source_set_callback ()? The callback would handle the input side from the host to my application.
