Member Function Documentation

readBox3D()

QgsBox3D QgsXmlUtils::readBox3D ( const QDomElement &  element )

static

Decodes a DOM element to a 3D box.

Parameters

element

DOM document

Returns

decoded 3D box

Since

QGIS 3.36

Definition at line 39 of file qgsxmlutils.cpp.

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

Definition at line 118 of file qgsxmlutils.h.

readMapUnits()

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

static

Parameters

element

DOM element to decode

Returns

distance units

Definition at line 293 of file qgsxmlutils.cpp.

writeBox3D()

QDomElement QgsXmlUtils::writeBox3D ( const QgsBox3D &  box, QDomDocument &  doc, const QString &  elementName = QStringLiteral( "extent3D" )  )

static

Encodes a 3D box to a DOM element.

Parameters

box	3D box to encode
doc	DOM document
elementName	name of the DOM element

Returns

element containing encoded 3D box

Since

Definition at line 106 of file qgsxmlutils.cpp.

writeMapUnits()

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

static

Parameters

units	units to encode
doc	DOM document

Returns

element containing encoded units

Definition at line 94 of file qgsxmlutils.cpp.

writeRectangle()

QDomElement QgsXmlUtils::writeRectangle ( const QgsRectangle &  rect, QDomDocument &  doc, const QString &  elementName = QStringLiteral( "extent" )  )

static

Encodes a rectangle to a DOM element.

Parameters

rect	rectangle to encode
doc	DOM document
elementName	name of the DOM element

Returns

element containing encoded rectangle

Definition at line 119 of file qgsxmlutils.cpp.

writeVariant()

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