MenuToolButtonProtocol
public protocol MenuToolButtonProtocol : ToolButtonProtocol
A GtkMenuToolButton
is a GtkToolItem
that contains a button and
a small additional button with an arrow. When clicked, the arrow
button pops up a dropdown menu.
Use gtk_menu_tool_button_new()
to create a new
GtkMenuToolButton
.
GtkMenuToolButton as GtkBuildable
The GtkMenuToolButton implementation of the GtkBuildable interface supports adding a menu by specifying “menu” as the “type” attribute of a <child> element.
An example for a UI definition fragment with menus:
<object class="GtkMenuToolButton">
<child type="menu">
<object class="GtkMenu"/>
</child>
</object>
The MenuToolButtonProtocol
protocol exposes the methods and properties of an underlying GtkMenuToolButton
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 MenuToolButton
.
Alternatively, use MenuToolButtonRef
as a lighweight, unowned
reference if you already have an instance you just want to use.

-
onShowMenu(flags:
Extension methodhandler: ) The
show-menu
signal is emitted before the menu is shown.It can be used to populate the menu on demand, using
gtk_menu_tool_button_set_menu()
.Note that even if you populate the menu dynamically in this way, you must set an empty menu on the
GtkMenuToolButton
beforehand, since the arrow is made insensitive if the menu is not set.Note
This represents the underlyingshow-menu

onNotifyMenu(flags:
Extension methodhandler: ) 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 tog_object_set_property()
results innotify
being emitted, even if the new value is the same as the old. If they did passG_PARAM_EXPLICIT_NOTIFY
, then this signal is emitted only when they explicitly callg_object_notify()
org_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.
Note
This represents the underlyingnotify::menu
