mafw.steering_gui.models.filter_tree_model

Tree model representing the filter configuration hierarchy.

Author:: Bulgheroni Antonio (antonio.bulgheroni@ec.europa.eu)
Description:: QAbstractItemModel implementation for displaying and editing filters, conditions, and logic associated with a processor.

Classes

`ConditionKey`(model_name, field_name, ...)	Stable key describing a condition entry in the filter tree.
`FilterNodeType`(*values)	Types of nodes in the filter tree.
`FilterTreeItem`(node_type[, data, parent, key])	Internal node for the FilterTreeModel.
`FilterTreeModel`(config[, parent])	Tree model for processor filters.
`LogicKey`(model_name, field_name)	Stable key describing a logic entry in the filter tree.
