GridViewProtocol

public protocol GridViewProtocol : ListBaseProtocol

GtkGridView presents a large dynamic grid of items.

GtkGridView uses its factory to generate one child widget for each visible item and shows them in a grid. The orientation of the grid view determines if the grid reflows vertically or horizontally.

GtkGridView allows the user to select items according to the selection characteristics of the model. For models that allow multiple selected items, it is possible to turn on rubberband selection, using [propertyGtk.GridView:enable-rubberband].

To learn more about the list widget framework, see the overview.

CSS nodes

├── child[.activatable]

├── child[.activatable]


╰── [rubberband]

GtkGridView uses a single CSS node with name gridview. Each child uses a single CSS node with name child. If the [propertyGtk.ListItem:activatable] property is set, the corresponding row will have the .activatable style class. For rubberband selection, a subnode with name rubberband is used.

Accessibility

GtkGridView uses the GTK_ACCESSIBLE_ROLE_GRID role, and the items use the GTK_ACCESSIBLE_ROLE_GRID_CELL role.

The GridViewProtocol protocol exposes the methods and properties of an underlying GtkGridView 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 GridView. Alternatively, use GridViewRef as a lighweight, unowned reference if you already have an instance you just want to use.

  • onActivate(flags:handler:) Extension method

    Emitted when a cell has been activated by the user, usually via activating the GtkGridView|list.activate-item action.

    This allows for a convenient way to handle activation in a gridview. See [propertyGtk.ListItem:activatable] for details on how to use this signal.

    Note

    This represents the underlying activate signal

    Declaration

    Swift

    @discardableResult
    @inlinable
    func onActivate(flags: ConnectFlags = ConnectFlags(0), handler: @escaping (_ unownedSelf: GridViewRef, _ position: UInt) -> Void) -> Int

    Parameters

    flags

    Flags

    unownedSelf

    Reference to instance of self

    position

    position of item to activate

    handler

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

  • activateSignal Extension method

    Typed activate signal for using the connect(signal:) methods

    Declaration

    Swift

    static var activateSignal: GridViewSignalName { get }
  • 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.

    Swift
