A widget for displaying grids.
Gtk::GridView is a widget to present a view into a large dynamic grid of items.
Gtk::GridView 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.
Gtk::GridView 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 set_enable_rubberband().
