Manages an editor widget Widget and wrapper share the same parent.
Wraps a text widget.
virtual void setEnabled(bool enabled) override
Is used to enable or disable the edit functionality of the managed widget.
virtual void showIndeterminateState()
Sets the widget to display in an indeterminate "mixed value" state.
virtual bool valid() const =0
Return 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.
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.
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.
