You can connect to the "map-event" signal of the popup widget: https://developer.gnome.org/gtk3/stable/GtkWidget.html#GtkWidget-map-event or to the "select" signal of the menu item which owns the popup: https://developer.gnome.org/gtk3/stable/GtkMenuItem.html#GtkMenuItem-select The "activate" and "activate-item" signals are probably not good because in Ubuntu Unity I've seen them emitted even when the popups are not opened. Also I am not sure if they are emitted when a user hovers the mouse over the item which opens the popup.
