Manages an editor widget Widget and wrapper share the same parent.
virtual QVariant value() const =0
Will be used to access the widget's value.
virtual void showIndeterminateState()
Sets the widget to display in an indeterminate "mixed value" state.
Wraps a value map widget.
Represents a vector layer which manages a vector based data sets.
