readFlagAttribute()

template<class T >

static T QgsXmlUtils::readFlagAttribute ( const QDomElement &  element, const QString &  attributeName, T  defaultValue  )

inlinestatic

Read a flag value from an attribute of the element.

Parameters

element	the element to read the attribute from
attributeName	the attribute name
defaultValue	the default value as a flag

Note

The flag value is a text as returned by

See also

QMetaEnum::valueToKeys. The flag must have been declared with Q_ENUM macro.

Since

QGIS 3.4
