Re: Memory allocation in TreeView and TreeModel

Hi,

I'm asking this for clarification as much as anything else.

I have previously been writing strings into G_TYPE_STRING columns of a 
GtkListStore (using gtk_list_store_set) and assuming that GTK will use the 
already-allocated strings in the tree.

I now have a suspicion that GTK is actually copying these strings and using 
its own copies in the list model. So if appropriate, I should be freeing my 
original strings after writing them using gtk_list_store_set. Can anyone 
confirm this?
It will be a copy.
 From a basic code-test, I am also under the impression that when using 
gtk_tree_model_get on a G_TYPE_STRING column, the string returned will be a 
copy of the string used internally for the tree model - and therefore I should 
free it once I'm done with it. I'd be grateful for confirmation on this point too.
Yes, that will also be a copy. free it.
If this copying is undesired, you could use G_TYPE_POINTER
