virtual bool valid()=0
Return true if the widget has been properly initialized.
void valueChanged()
Will call the value() method to determine the emitted value.
Manages an editor widget Widget and wrapper share the same parent.
virtual QVariant value()=0
Will be used to access the widget's value.
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.
Represents a vector layer which manages a vector based data sets.
