I keep getting compiler warning, although I have (I think) the right types:

What are the proper casting (macros) to use?
Where can I find the list of macros?

Thanks, Peter

myfunc()
{
GtkTreeModel *model;
GtkTreeStore *store;
 ...
    model = gtk_tree_view_get_model(GTK_TREE_VIEW(view));
    store = GTK_LIST_STORE ( model );  //   warning: assignment from incompatible pointer type


  gtk_list_store_append (store, &iter); // passing argument 1 of ‘gtk_list_store_append’ from incompatible pointer type
...
}

Macro of type cast in GTK , have some custom.
the warning in your code is cause

Code: (Plaintext)

GtkTreeStore *store;
store = GTK_LIST_STORE ( model );


As in the definition variable store is GtkTreeStore but you use GTK_LIST_STORE .
You should use
Code: (Plaintext)
1
2
3

GtkListStore *store ;

to define your variable.
