Manages an editor widget Widget and wrapper share the same parent.
virtual bool valid() const =0
Returns true if the widget has been properly initialized.
Wraps a range widget.
virtual QWidget * createWidget(QWidget *parent)=0
This method should create a new widget with the provided parent.
virtual void initWidget(QWidget *editor)
This method should initialize the editor widget with runtime data.
virtual void setValue(const QVariant &value)=0
Is called, when the value of the widget needs to be changed.
#define SIP_NO_FILE
Definition: qgis_sip.h:23
virtual QVariant value() const =0
Will be used to access the widget&#39;s value.
Represents a vector layer which manages a vector based data sets.
