- * @device: (allow-none): a #GdkDevice
- * @parent_menu_shell: (allow-none): the menu shell containing the triggering
- * menu item, or %NULL
- * @parent_menu_item: (allow-none): the menu item whose activation triggered
- * the popup, or %NULL
- * @func: (allow-none): a user supplied function used to position the menu,
- * or %NULL
- * @data: (allow-none): user supplied data to be passed to @func
- * @destroy: (allow-none): destroy notify for @data
- * @button: the mouse button which was pressed to initiate the event
- * @activate_time: the time at which the activation event occurred
- *
- * Displays a menu and makes it available for selection.
- *
- * Applications can use this function to display context-sensitive menus,
- * and will typically supply %NULL for the @parent_menu_shell,
- * @parent_menu_item, @func, @data and @destroy parameters. The default
- * menu positioning function will position the menu at the current position
- * of @device (or its corresponding pointer).
- *
- * The @button parameter should be the mouse button pressed to initiate
- * the menu popup. If the menu popup was initiated by something other than
- * a mouse button press, such as a mouse button release or a keypress,
- * @button should be 0.
- *
- * The @activate_time parameter is used to conflict-resolve initiation of
- * concurrent requests for mouse/keyboard grab requests. To function
- * properly, this needs to be the time stamp of the user event (such as
- * a mouse click or key press) that caused the initiation of the popup.
- * Only if no such event is available, gtk_get_current_event_time() can
- * be used instead.
- *
- * Since: 3.0
