GtkFlowBox is a container that its children in a reflowing grid, which can be oriented horizontally or vertically. It is similar to GtkListBox in that the children can be sorted and filtered, and by requiring a dedicated child widget type, GtkFlowBoxChild. It is similar to GtkTreeView in that is supports a full set of selection modes, including rubberband selection. This is the culmination of work that has happened in the egg-list-box module, and earlier in libegg. The origins of this code are the EggSpreadTable in libegg, which was written by Tristan van Berkom. It was moved to egg-list-box and renamed EggFlowBox by Jon McCann, and I gave it some finishing touched in the flowbox-improvements branch of that module.
