Add GtkFlowBox 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.

testflowbox: Add an example with buttons This example populates a flow box with buttons, and makes the flow box children unfocusable, with the intention that the focus moves directly between the buttons. Currently, keynav does not work at all in this case.

Add GtkFlowBox 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.
