ToolItemProtocol

public protocol ToolItemProtocol : ActivatableProtocol, BinProtocol

GtkToolItems are widgets that can appear on a toolbar. To create a toolbar item that contain something else than a button, use gtk_tool_item_new(). Use gtk_container_add() to add a child widget to the tool item.

For toolbar items that contain buttons, see the GtkToolButton, GtkToggleToolButton and GtkRadioToolButton classes.

See the GtkToolbar class for a description of the toolbar widget, and GtkToolShell for a description of the tool shell interface.

The ToolItemProtocol protocol exposes the methods and properties of an underlying GtkToolItem instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see ToolItem. Alternatively, use ToolItemRef as a lighweight, unowned reference if you already have an instance you just want to use.

  • This signal is emitted when the toolbar needs information from tool_item about whether the item should appear in the toolbar overflow menu. In response the tool item should either

    • call gtk_tool_item_set_proxy_menu_item() with a nil pointer and return true to indicate that the item should not appear in the overflow menu

    • call gtk_tool_item_set_proxy_menu_item() with a new menu item and return true, or

    • return false to indicate that the signal was not handled by the item. This means that the item will not appear in the overflow menu unless a later handler installs a menu item.

    The toolbar may cache the result of this signal. When the tool item changes how it will respond to this signal it must call gtk_tool_item_rebuild_menu() to invalidate the cache and ensure that the toolbar rebuilds its overflow menu.

  • The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

    Note that getting this signal doesn’t itself guarantee that the value of the property has actually changed. When it is emitted is determined by the derived GObject class. If the implementor did not create the property with G_PARAM_EXPLICIT_NOTIFY, then any call to g_object_set_property() results in notify being emitted, even if the new value is the same as the old. If they did pass G_PARAM_EXPLICIT_NOTIFY, then this signal is emitted only when they explicitly call g_object_notify() or g_object_notify_by_pspec(), and common practice is to do that only when the value has actually changed.

    This signal is typically used to obtain change notification for a single property, by specifying the property name as a detail in the g_signal_connect() call, like this:

    (C Language Example):

    g_signal_connect (text_view->buffer, "notify::paste-target-list",
                  G_CALLBACK (gtk_text_view_target_list_notify),
                  text_view)

    It is important to note that you must use canonical parameter names as detail strings for the notify signal.
