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.
void setFeature(const QgsFeature &feature) override
Will be called when the feature changes.
void setEnabled(bool enabled) override
Is used to enable or disable the edit functionality of the managed widget.
virtual void setHint(const QString &hintText)
Add a hint text on the widget.
The feature class encapsulates a single feature including its unique ID, geometry and a list of field...
Definition qgsfeature.h:56
Wraps a text widget.
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.
