QGraphicsObject
QObject
QGraphicsItem

Constructor

__init__

Methods

`indexForInput`	Returns the index for the input with the specified parameter name, or -1 if the parameter could not be matched.
`indexForOutput`	Returns the index for the output with the specified name, or -1 if the output could not be matched.
`results`	Returns the results for this child algorithm for the last model execution through the dialog.
`setOutdated`	Flags the algorithm as possibly being outdated (i.e. previous results are invalid due to changes elsewhere in the model).
`setProgress`	Sets the child's progress.
`setResults`	Sets the results obtained for this child algorithm for the last model execution through the dialog.
`setSinkFeatureCount`	Sets the feature count for the sink attached to the specified output.
`setSourceFeatureCount`	Sets the feature count for the source attached to the specified input.
`setStarted`	Flags the algorithm as having started.

Signals

`rebuildConfigurationDockWidget`	Requests that any associated configuration dock widget is rebuilt to reflect the current state of the child algorithm.
`runFromHere`	Emitted when the user opts to run the model from this child algorithm.
`runSelected`	Emitted when the user opts to run selected steps from the model.
`showLog`	Emitted when the user opts to view the previous log from this child algorithm.
`showPreviousResults`	Emitted when the user opts to view previous results from this child algorithm.

class qgis.gui.QgsModelChildAlgorithmGraphicItem[source]¶

Bases: QgsModelComponentGraphicItem

__init__(child: QgsProcessingModelChildAlgorithm | None, model: QgsProcessingModelAlgorithm | None, parent: QGraphicsItem | None)¶

Constructor for QgsModelChildAlgorithmGraphicItem for the specified child, with the specified parent item.

The model argument specifies the associated processing model. Ownership of model is not transferred, and it must exist for the lifetime of this object.

Ownership of child is transferred to the item.

Parameters:

child (Optional[QgsProcessingModelChildAlgorithm])
model (Optional[QgsProcessingModelAlgorithm])
parent (Optional[QGraphicsItem])

indexForInput(self, parameterName: str | None) → int[source]¶

Returns the index for the input with the specified parameter name, or -1 if the parameter could not be matched.
