A cross platform button subclass for selecting colors.
void valueChanged()
Will call the value() method to determine the emitted value.
Manages an editor widget Widget and wrapper share the same parent.
QgsColorWidgetWrapper(QgsVectorLayer *vl, int fieldIdx, QWidget *editor=0, QWidget *parent=0)
void setContext(const QString context)
Sets the context string for the color button.
QVariant value()
Will be used to access the widget's value.
void setColor(const QColor &color)
Sets the current color for the button.
void initWidget(QWidget *editor)
This method should initialize the editor widget with runtime data.
QWidget * createWidget(QWidget *parent)
This method should create a new widget with the provided parent.
void setValue(const QVariant &value)
Represents a vector layer which manages a vector based data sets.
