Member Function Documentation

◆ mapCanvas()

QgsMapCanvas * QgsProcessingParameterWidgetContext::mapCanvas ( ) const

Returns the map canvas associated with the widget.

See also: setMapCanvas()

Definition at line 39 of file qgsprocessingwidgetwrapper.cpp.

◆ model()

QgsProcessingModelAlgorithm * QgsProcessingParameterWidgetContext::model ( ) const

Returns the model which the parameter widget is associated with.

See also: setModel(); modelChildAlgorithmId()

Definition at line 64 of file qgsprocessingwidgetwrapper.cpp.

◆ modelChildAlgorithmId()

QString QgsProcessingParameterWidgetContext::modelChildAlgorithmId ( ) const

Returns the child algorithm ID within the model which the parameter widget is associated with.

See also: setModelChildAlgorithmId(); model()

Definition at line 54 of file qgsprocessingwidgetwrapper.cpp.

◆ project()

QgsProject * QgsProcessingParameterWidgetContext::project ( ) const

Returns the project associated with the widget.

See also: setProject()

Definition at line 49 of file qgsprocessingwidgetwrapper.cpp.

◆ setMapCanvas()

void QgsProcessingParameterWidgetContext::setMapCanvas ( QgsMapCanvas * canvas )

Sets the map canvas associated with the widget.

This allows the widget to retrieve the current map scale and other properties from the canvas.

See also: mapCanvas()

Definition at line 34 of file qgsprocessingwidgetwrapper.cpp.

◆ setModel()

void QgsProcessingParameterWidgetContext::setModel ( QgsProcessingModelAlgorithm * model )

Sets the model which the parameter widget is associated with.

See also: model(); setModelChildAlgorithmId()

Definition at line 69 of file qgsprocessingwidgetwrapper.cpp.

◆ setModelChildAlgorithmId()

void QgsProcessingParameterWidgetContext::setModelChildAlgorithmId ( const QString & id )

Sets the child algorithm id within the model which the parameter widget is associated with.

See also: modelChildAlgorithmId(); setModel()

Definition at line 59 of file qgsprocessingwidgetwrapper.cpp.

◆ setProject()

void QgsProcessingParameterWidgetContext::setProject ( QgsProject * project )

Sets the project associated with the widget.

This allows the widget to retrieve the map layers and other properties from the correct project.
