Search widget for the children of a relation.
Shows a search widget on a filter form.
virtual QString expression() const =0
Will be used to access the widget's value.
virtual void setExpression(const QString &expression)=0
Set the expression which is currently used as filter for this widget.
virtual bool applyDirectly()=0
If this is true, then this search widget should take effect directly when its expression changes.
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 QWidget * createWidget(QWidget *parent)=0
This method should create a new widget with the provided parent.
