Manages an editor widget Widget and wrapper share the same parent.
virtual void updateConstraintWidgetStatus()
This should update the widget with a visual cue if a constraint status changed.
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 key/value widget.
Widget allowing to edit a QVariantMap, using a table.
Represents a vector layer which manages a vector based data sets.
virtual bool valid() const =0
Returns true if the widget has been properly initialized.
virtual void initWidget(QWidget *editor)
This method should initialize the editor widget with runtime data.
virtual QWidget * createWidget(QWidget *parent)=0
This method should create a new widget with the provided parent.
