virtual void showIndeterminateState()
Sets the widget to display in an indeterminate "mixed value" state.
virtual bool valid() const =0
Returns true if the widget has been properly initialized.
void setFeature(const QgsFeature &feature) override
Will be called when the feature changes.
virtual QWidget * createWidget(QWidget *parent)=0
This method should create a new widget with the provided parent.
