Detailed Description

The RadialTree implements a tree representation of item from the given model.

Contrary to QTreeView, a radial tree is not a hierarchical list: the root is placed at the center and all children are placed on concentric circles.

Member Function Documentation

virtual void positionsInView ( )

virtual

Defines the positions of the items in the view relative to their positions in the tree.

This function uses the margins and the item size to calculate

Implements AbstractTree.

void updatePerimeter ( )

protected

Updates the outer perimeter.

It used to defines the size needed by the view.
