Displaying contents of a folder in gtk_tree_view

[Tom <haifischhathunger web de>]

Hi!

I'm writing a program which uses "gtk_tree_view" to display the contents 
of a folder. This folder is selected by the user through a 
"gtk_file_chooser_dialog". Now while I can get my app to display the 
files of any folder I want when I tell it which folder to scan by 
'hardcoding' in the path, I can't figure out how to call the appropriate 
functions when 'user-selecting' this path. To clarify:

static GtkTreeModel *create_and_fill_model (void)
{
	GtkListStore    *store;
	...
	scanFiles(folder);
        printf("Files found: %d\n",count);
        for (cnt = 0; cnt < count; ++cnt)
        {
            file = files[cnt]->d_name;
            printf ("%s\n",file);
            gtk_list_store_append (store, &iter);
            gtk_list_store_set (store, &iter,COL_TYPE, 							 
"none",COL_NAME, file,-1);
        }
	return GTK_TREE_MODEL (store);
}
static GtkWidget *create_view_and_model (void)
{
	GtkWidget       *view;
	GtkTreeModel    *model;
	...
	model = create_and_fill_model ();
	...
	return view;
}
static void openDialog( GtkWidget *widget,GtkWidget *window)
{
	GtkWidget *dialogOPEN;
	...
        folder = gtk_file_chooser_get_current_folder(...)
        create_view_and_model();
        ...	
    }
}
int main( int argc,char *argv[] )
{
	GtkWidget *list;
	GtkWidget *buttonOPEN;	
	...
	list = create_view_and_model();
	buttonOPEN = gtk_button_new_from_stock (GTK_STOCK_OPEN);
    	g_signal_connect (G_OBJECT 
(buttonOPEN),"clicked",G_CALLBACK 						(openDialog),(gpointer) window);
	...
}

This is the basic structure of my program. I'm guessing that because I 
am 'recalling' "create_view_and_model" from within "openDIALOG" the list 
is not getting drawn inside the widget. I know that the 
'data'(filenames) is getting to my function, as I can dump them with 
printf();
How do I solve this?

Sorry for the long post...
