static QList< QPair< QString, QString > > pyramidResamplingMethods(const QString &providerKey)
Returns a list of pyramid resampling method name and label pairs for given provider.
void optionsChanged()
Emitted when the options configured in the widget are changed.
void someValueChanged()
Emitted when settings are changed in the widget.
QgsRasterPyramidsOptionsWidget(QWidget *parent=nullptr, const QString &provider="gdal")
Constructor for QgsRasterPyramidsOptionsWidget.
void overviewListChanged()

This class is a composition of two QSettings instances:
Definition qgssettings.h:64
QVariant value(const QString &key, const QVariant &defaultValue=QVariant(), Section section=NoSection) const
Returns the value for setting key.
void setValue(const QString &key, const QVariant &value, QgsSettings::Section section=QgsSettings::NoSection)
Sets the value of setting key to value.
