I'm afraid Mark is right: you need to g_strdup() your keys and values
before you put them in the hash. It's the downside of C ... you have to
do the storage management.

In regards to g_strdup, do I need to allocate the memory for the returned string.
It's not

This has nothing to do with GTK as such, but I can't find a more appropriate
place to post about glib.
Trying to hammer out some code using a bunch of GStrings, I ran across a
case where I wanted to concatenate them into a new GString, separated by a
delimiter - much like g_strjoin. To my

strdup is not in my copy of ANSI c, which is in the KN King book,

Hallo!
I'm developing an application using gtk2 and I have some questions regarding
GtkTreeView interface. Regrettably, on this part the documentation is what I
would call terse :-)
Now to the questions:

I found a way to solve this (possibly uninteresting) problem. My sample
code is 500 lines, though, so instead of posting it to the group, would be
happy to directly email the code to anyone who emails me privately.
I ended up doing the bulk of the work in a drag_drop handler.
