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

readMapUnits()

QgsUnitTypes::DistanceUnit QgsXmlUtils::readMapUnits ( const QDomElement &  element )

static

Decodes a distance unit from a DOM element.

Parameters

element

DOM element to decode

Returns

distance units

Definition at line 37 of file qgsxmlutils.cpp.

readVariant()

QVariant QgsXmlUtils::readVariant ( const QDomElement &  element )

static

Read a QVariant from a QDomElement.

Definition at line 207 of file qgsxmlutils.cpp.

writeMapUnits()

QDomElement QgsXmlUtils::writeMapUnits ( QgsUnitTypes::DistanceUnit  units, QDomDocument &  doc  )

static

Encodes a distance unit to a DOM element.

Parameters

units	units to encode
doc	DOM document

Returns

element containing encoded units

writeRectangle()

QDomElement QgsXmlUtils::writeRectangle ( const QgsRectangle &  rect, QDomDocument &  doc  )

static

Definition at line 79 of file qgsxmlutils.cpp.

writeVariant()

QDomElement QgsXmlUtils::writeVariant ( const QVariant &  value, QDomDocument &  doc  )
