__init__(desc: str | None = '')

Constructor

Parameters:

desc (Optional[str] = '')

addSubTask(self, subTask: QgsTask | None)

Add a subtask and transfer its ownership

The parent task must be added to a QgsTaskManager for subtasks to be utilized. Subtasks should not be added manually to a QgsTaskManager, rather, only the parent task should be added to the manager.

For now, subtasks can NOT be nested.

Parameters:

subTask (Optional[QgsTask])
