GridView
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 property@Gtk.GridView:enable-rubberband.
To learn more about the list widget framework, see the section-list-widget.html.
Actions
GtkGridView defines a set of built-in actions:
list.activate-itemactivates the item at given position by emitting the the signal@Gtk.GridView::activate signal.
CSS nodes

╰── [rubberband]GtkGridView uses a single CSS node with name gridview. Each child uses a single CSS node with name child. If the property@Gtk.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.
