Hi all,
I have a program in which I call gtk_toggle_button_set_active to
enable a check box based on a previously set variable when a dialog
box is created. I've set up a "toggled" event handler that will print
out a message to console. The docs state that
gtk_toggle_button_set_active will always e
You can use gtk_widget_show to bring up your dialog, and then use
gtk_set_transient_for to mark it "modal to only one window", to get
behavior similar to firefox.

Hi all,
I'm writing a program that, like gimp, has a control window, from

I'm writing a program that needs to be "single-instance". The program

It wouldn't matter too much, since most screens would only have a

I've handled such cases by using g_idle_add when I get an update of the
variable's status, and have the idle function update the text box.

Why not use gtk_window_fullscreen? I've only tried it on a Gnome

I have a question about the cross-platform compatibility of
GIOChannels, between win32 (using mingw32) and Linux, when using
pipes. I am using g_spawn_async_with_pipes to spawn a series of
programs that do some processing and deliver results. Specifically,
I'm using the Generic Mapping Tools (GMT).
Not sure how you'd do this in gdk directly, but I can think of two alternatives:
a. Use Cairo (supports alpha channels, and gives you awesome-looking
antialiased triangles to boot)
b. Use gdk to render to 30 different GdkPixbufs, then composite them
together. The composite functions take an alpha p

I want to derive a new class from GtkWindow to represent a top-level

glade_xml_get_widget functions returns a new object, I'm not sure what
to do in the object's "init_instance" function to copy the properties

If you're using lookup_widget(), that means you're using Glade's code

especially if you're not too far into your project.

Correct me if I'm wrong, but if you're using GDK, I think you should
use pixmaps instead of GdkPixBufs. The docs say that pixbufs are
client-side, while pixmaps are server side, so redrawing a pixbuf will
be more expensive. I also take this to mean that it's possible for an
X server to store a pixm
