mafw.steering_gui.models

GUI-facing models and Qt wrappers for steering metadata.

Author:: Bulgheroni Antonio
Description:: Holds the editable UI models that wrap steering builder domain objects.

class mafw.steering_gui.models.PipelineItem(config: ~mafw.steering.models.ProcessorConfig | ~mafw.steering.models.GroupConfig, parent: ~mafw.steering_gui.models.pipeline.PipelineItem | None = None, children: list[~mafw.steering_gui.models.pipeline.PipelineItem] = <factory>)[source]

Bases: object

UI wrapper around a processor or group configuration.

Parameters:

config – Domain configuration backing the item.
parent – Parent pipeline item (None when top-level).
children – Ordered list of child items.

is_group() → bool[source]: Return True if this item wraps a group configuration.

name() → str[source]: Return the replica-aware processor name or group name.

class mafw.steering_gui.models.ProcessorPipeline(items: list[~mafw.steering_gui.models.pipeline.PipelineItem] = <factory>)[source]

Bases: object

Container for the current processor pipeline tree.

Parameters:: items – Top-level pipeline items in execution order.

class mafw.steering_gui.models.ProcessorPipelineModel(pipeline: ProcessorPipeline | None = None, parent: QObject | None = None)[source]

Bases: QAbstractItemModel

Expose a ProcessorPipeline as a tree-structured Qt model.

pipeline() → ProcessorPipeline[source]: Return the currently attached pipeline.

root_items() → list[PipelineItem][source]: Return the top-level pipeline items.

set_pipeline(pipeline: ProcessorPipeline) → None[source]: Replace the pipeline data and reset the model.

class mafw.steering_gui.models.SteeringTreeModel(controller: object, pipeline: ProcessorPipeline | None = None, parent: QObject | None = None)[source]

Bases: QAbstractItemModel

Tree model exposing the steering sections and embedded processor pipeline.

pipeline_item_from_index(index: QModelIndex | QPersistentModelIndex) → PipelineItem | None[source]: Return the pipeline item stored at the given index, if any.

section_key_from_index(index: QModelIndex | QPersistentModelIndex) → str | None[source]: Return the section key stored at the given index, if any.

set_pipeline(pipeline: ProcessorPipeline) → None[source]: Replace the pipeline subtree and reset the model.

class mafw.steering_gui.models.SteeringTreeRoles(*values)[source]

Bases: IntEnum

Custom roles exported by the steering tree model.

Modules

`filter_tree_model`	Tree model representing the filter configuration hierarchy.
`pipeline`	UI-only pipeline structures used to render editable processor hierarchies.
`processor_pipeline_model`	Qt model for the processor pipeline tree.
`steering_tree_model`	Composite Qt model that embeds the processor pipeline under the steering tree.
