This tutorial is outdated: it refers to version 0.4 of clutter that now is VERY old.
Last time we have seen how to draw the (maybe) most basic shape of clutter: the rectangles. We also positioned them together in the stage, and said (in part one) that the stage is a special kind of container.
Today it’s time to explain better what groups are and how to use them, so I’ll introduce to you the ClutterGroup and the ClutterHBox/ClutterVBox.
