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.

  • ptr

    Untyped pointer to the underlying GtkMenuToolButton instance.

    Declaration

    Swift

    var ptr: UnsafeMutableRawPointer! { get }
  • menu_tool_button_ptr Default implementation

    Typed pointer to the underlying GtkMenuToolButton instance.

    Default Implementation

    Return the stored, untyped pointer as a typed pointer to the GtkMenuToolButton instance.

    Declaration

    Swift

    var menu_tool_button_ptr: UnsafeMutablePointer<GtkMenuToolButton>! { get }

MenuToolButton signals

    Parameters

    signal

    The signal to connect

    flags

    The connection flags to use

    data

    A pointer to user data to provide to the callback

    destroyData

    A GClosureNotify C function to destroy the data pointed to by userData

    handler

    The Swift signal handler (function or callback) to invoke on the given signal

    Return Value

    The signal handler ID (always greater than 0 for successful connections)

  • Connect a C signal handler to the given, typed MenuToolButtonSignalName signal

    Declaration

    Swift

    @discardableResult
    @inlinable
    func connect(signal s: MenuToolButtonSignalName, flags f: ConnectFlags = ConnectFlags(0), data userData: gpointer!, destroyData destructor: GClosureNotify? = nil, signalHandler h: @escaping GCallback) -> Int

    Return Value

    The signal handler ID (always greater than 0 for successful connections)

  • onShowMenu(flags:handler:) Extension method

    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 underlying show-menu signal

    Declaration

    Swift

    @discardableResult
    @inlinable
    func onShowMenu(flags: ConnectFlags = ConnectFlags(0), handler: @escaping (_ unownedSelf: MenuToolButtonRef) -> Void) -> Int

    Parameters

    flags

    Flags

    unownedSelf

    Reference to instance of self

    handler

    The signal handler to call Run the given callback whenever the showMenu signal is emitted

  • showMenuSignal Extension method

    Typed show-menu signal for using the connect(signal:) methods

    Declaration

    Swift

    static var showMenuSignal: MenuToolButtonSignalName { get }
  • onNotifyMenu(flags:handler:) Extension method

    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.

    Note

    This represents the underlying notify::menu signal

    Declaration

    Swift

    @discardableResult
    @inlinable
    func onNotifyMenu(flags: ConnectFlags = ConnectFlags(0), handler: @escaping (_ unownedSelf: MenuToolButtonRef, _ pspec: ParamSpecRef) -> Void) -> Int

    Parameters

    flags

    Flags

    unownedSelf

    Reference to instance of self

    pspec

    handler
