Hello,
how can I set up a GtkFileChooser so that users can select a folder rather
than a file? As it is, one selects a a folder and clicks "open" (hoping to
select that folder), but rather than returning that folder's path, the
dialog just opens the folder and shows its contents.

In a way, yes. It's impossible to make C-specific queries because a single C
in the query is either ignored, or machtches pretty much the entire WWW. And
C API docs seldom mention the fact that they're intended to be used

Useless cast, and useless parentheses around sizeof's operand.

Hello,
I've written some C code which at some point seems to be trampling over memory
that belongs to GTK-related stuff, which causes erratic crashed at some
unrelated point much later. This is of course not a GTK issue, just a
well-known phenomenon in general.

I'm currently struggling with the GtkExtra toolkit for generating 2D line

Yes! When I came back to C from C++ (I had done a large project for which C++

Ah, I'm using the Debian-supplied version 2.12.4, and your page refers to

OK, I've got something in the form of a GValue (in this case, integer numeric
data
obtained with gtk_container_child_get()), and I'd like to get access to the
actual number inside. How is this done? I've looked into GValue's
documentation, but all I see is stuff that deals only with GValues and

slightly asymmetric because of the empty label.
