Re: gtk_combo_set_popdown_strings() coppies data?

[Marco Quezada <mquezada nlxcorp com>]

The combo box is a widget so you destroy the combos by calling something like:

gtk_object_destroy(GTK_OBJECT(variables_combo));

Where variables_combo is the combo graphic, not the list of strings.

Clearing the GList is very simple, the GList is a pointer to the list of strings so
all you have to do is set the pointer to NULL and your GList will be empty, for
example:

if your GList is declared as something like this:

GList *variables_list_items;

Then in your code where you decide to clear the contents of the GList do the
following:

variables_list_items = NULL;
