Not at all, just casting, (Type) pointer.
Your problems is with callback functions, isn't it ?
typedef struct _MyData {
......
} MyData;
MyData *data; // your struct
g_signal_connect ((gpointer) one_button,
"clicked",
G_CALLBACK (on_button_clicked),
(gpointer) data); // casting to gpointer
/* callback function */
void
on_button_clicked (GtkButton * button,
gpointer user_data)
{
MyData *data;
data = (MyData*) user_data; // casting from gpointer
/* you can now access data->whatever */
}
Hope this helps.
