Constructor & Destructor Documentation

◆ FeatureCommandBase()

		QUndoCommand *	parent = `nullptr`
	)

Member Function Documentation

◆ lastError()

QString openswmmvis::map::FeatureCommandBase::lastError ( ) const

inline

The message from the last failed apply, for the caller to show. Empty when the command has not failed.

◆ layer()

FeatureLayer * openswmmvis::map::FeatureCommandBase::layer ( ) const

inline

Here is the caller graph for this function:

◆ recordFailure()

void openswmmvis::map::FeatureCommandBase::recordFailure ( const QString & err ) const

protected

Log err and remember it. Commands cannot show UI from redo()/undo() — QUndoStack may be replaying — so a failure is recorded, logged, and surfaced by whoever pushed the command.
