How to: Implement a Custom Layout Algorithm

  • 4 minutes to read

To implement a custom layout algorithm, design a class inheriting the abstract TreeMapLayoutAlgorithm class and implement its TreeMapLayoutAlgorithmBase.Calculate method, which will calculate item layouts using a custom algorithm.

In this example, items are arranged depending on the empty space width/height ratio.
