Tree Outline with lazy loading

Here is my first outline tree. It can be populated at once or lazily on demand. The demo app has one StaticTree form that loads the whole tree at once and one DynamicTree form that loads only the first level when the form opens and adds the children on demand. The tree lives in a LinearPanel on the main form and uses one TreeOutline instance on each node and one TreeData instance on each leaf. The TreeData is very simple: it is just a form that shows the data on each leaf. It can contain just…

It’s a tree that looks similar to yours, constructed from a set of hierarchical nodes that are linked together using a parent field.

You can add items dynamically by calling add_item, which does add_component to the parent node.
