GString in GtkTreeStore columns

[Konrad Anton <konrad minus1 de>]

Hello all,

the application I'm trying to implement contains a table view which is 
periodically updated. Some of the columns shall contain dynamically 
sprintf'd strings. Imagine a "top" utility which reads the processes' 
command lines from files and shows them in the "command line" column.

I'm currently using a GtkTreeView backed by a GtkTreeStore. My 
GtkTreeStore has a G_TYPE_STRING column for the command line, and I fill 
these cells with the C-string contents of computed GStrings. That works 
and leaks memory.

As far as I understand GObject's refcounting, it should be possible to 
have the GtkTreeStore own the allocated strings, so that the strings are 
freed automatically when I delete rows. However, when I change the 
column type to G_TYPE_GSTRING, the GtkCellRendererText refuses to render 
the cell contents due to their type.

What would be a smart way to store dynamic strings in a table without 
having to manage their memory manually?

Thanks,
Konrad
