Re: deleting entry from a combo box

[parthasarathi s a <parthasarathi mail cyberneme com>]

Here is the piece of code which deletes the item in the combo box. Everything works fine - until i call 
gtk_combo_set_popdown_strings() - it gives a secgmentation fault.
And without calling the gtk_combo_set_popdown_strings() the list in the combo box doesnt get updated.

Should i do anything else other than this?


        GList *lItems = NULL;
        GList *item = NULL ;
        GtkWidget *cmbAddedApps = gtk_object_get_data( GTK_OBJECT( wndmain), "cmbAddedApps");

        lItems = GTK_COMBO(cmbAddedApps)->list ; // REFERENCE THE LIST IN THE COMBO BOX
        item = GTK_LIST(lItems)->selection ;     // REFERENCE THE SELECTED ITEM IN THE LIST

        item = g_list_append(NULL,item->data) ;
        gtk_list_unselect_all(GTK_LIST(lItems)) ;
        gtk_list_remove_items(GTK_LIST(lItems),item) ;

        gtk_combo_set_popdown_strings( GTK_COMBO(cmbAddedApps), GTK_LIST(lItems));
