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.

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

onNotifyEnableRubberband(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.
