pluginplayer.tree_manager

Managing tree generation

The TreeManager class handles setting the module to be viewed in a tree view, and generates the tree with its connections.

When a user wants to view a module on the tree, they can select the Graph button from the PluginSection (left).

The Module will then be placed as the root node on the tree and it will build a map for each layer of the tree, adding a new layer with the submodules of the previous layer, including their mappings. This is done with the submodule_dependencies function.

The generate_tree function will use the built map to center and place the nodes into a tree like structure.

The add_connections function will then bind the mappings of each node with a line connecting them.

Deleting the tree

All canvas instructions and widgets added to the tree section are removed, and the set inputs and property types are cleared.
