QGraphicsAnchorLayout
The QGraphicsAnchorLayout is a very flexible layout, yet the concept is simple. By creating an anchor between two edges of two layout items you are giving the anchor layout a constraint to fulfill. In the simplest case you are just saying that the distance between the two layout edges should be a fixed distance. You can do this with the left, right, top, bottom and the “center edges” of any layout item. You can also have an edge that has several anchors connected to it. This is not possible with linear layout and it is partly possible with a grid layout. This allows you to build up the structure the layout should have. The layout will then try to fulfill the constraints you have given it by potentially growing or shrinking the layout items. You can also configure each anchor to grow or shrink if that is preferred.
