This is an abstract base class for any elements of a drag and drop form.
Q_DECL_DEPRECATED void accept()
Alias for save()
This class contains context information for attribute editor widgets.
Manages an editor widget Widget and wrapper share the same parent.
The feature class encapsulates a single feature including its id, geometry and a list of field/values...
Definition: qgsfeature.h:119
QgsVectorLayer * layer()
Returns the layer for which this form is shown.
virtual bool eventFilter(QObject *watched, QEvent *event)
Q_DECL_DEPRECATED void reject()
Alias for resetValues()
void setEditCommandMessage(const QString &message)
Sets the edit command message (Undo) that will be used when the dialog is accepted.
const QgsFeature & feature()
Represents a vector layer which manages a vector based data sets.
