The most used ways:
1. Allocate the structure and pass it to signal's callback, in your case:
typedef struct _MyCallbackArgs
{
GtkWidget *window;
GtkWidget *dir_list;
} MyCallbackArgs;
...
MyCallbackArgs *args = g_new (MyCallbackArgs, 1);
args->window = pWindow, args->dir_list = DirList;
g_signal_connect (pMenuItem, "activate", G_CALLBACK (OnFile), args);
2. Use the g_object_get/set_data () functions to store a pointer you
need in either pMenuItem or pWindow:

3. Use global variables.
You can search gtk-list and gtk-app-devel-list list to find some
additional info, there were many messages on this in the past.
