Function Documentation

_getProperties()

void _getProperties	(	const QDomDocument &	doc,
		QgsProjectPropertyKey &	project_properties )

Restores any optional properties found in "doc" to "properties".

properties tags for all optional properties. Within that there will be scope tags. In the following example there exist one property in the "fsplugin" scope. "layers" is a list containing three string values.

<properties name="properties">
  <properties name="fsplugin">
    <properties name="foo" type="int" >42</properties>
    <properties name="baz" type="int" >1</properties>
    <properties name="layers" type="QStringList">
      <value>railroad</value>
      <value>airport</value>
    </properties>
    <properties name="xyqzzy" type="int" >1</properties>
    <properties name="bar" type="double" >123.456</properties>
    <properties name="feature_types" type="QStringList">
       <value>type</value>
    </properties>
  </properties>
</properties>

Parameters

doc	xml document
project_properties	should be the top QgsProjectPropertyKey node.

addKey_()

QgsProjectProperty * addKey_	(	const QString &	scope,
		const QString &	key,
		QgsProjectPropertyKey *	rootProperty,
		const QVariant &	value,
		bool &	propertiesModified )

Adds the given key and value.

Parameters

scope	scope of key
key	key name
rootProperty	is the property from which to start adding
value	the value associated with the key
propertiesModified	the parameter will be set to true if the written entry modifies pre-existing properties

dump_()

void dump_

(

const QgsProjectPropertyKey &

topQgsPropertyKey

)

Definition at line 1326 of file qgsproject.cpp.

findKey_()

QgsProjectProperty * findKey_	(	const QString &	scope,
		const QString &	key,
		QgsProjectPropertyKey &	rootProperty )

Takes the given scope and key and convert them to a string list of key tokens that will be used to navigate through a Property hierarchy.

E.g., scope "someplugin" and key "/foo/bar/baz" will become a string list of { "properties", "someplugin", "foo", "bar", "baz" }. "properties" is always first because that's the permanent ``root'' Property node. */ QStringList makeKeyTokens_( const QString &scope, const QString &key ) { QStringList keyTokens = QStringList( scope ); keyTokens += key.split( '/', Qt::SkipEmptyParts );

be sure to include the canonical root node keyTokens.push_front( QStringLiteral( "properties" ) );

return keyTokens; }

/** Returns the property that matches the given key sequence, if any

Parameters

scope	scope of key
key	keyname
rootProperty	is likely to be the top level QgsProjectPropertyKey in QgsProject:e:Imp.

Returns

null if not found, otherwise located Property

getDataDefinedServerProperties()

QgsPropertyCollection getDataDefinedServerProperties	(	const QDomDocument &	doc,
		const QgsPropertiesDefinition &	dataDefinedServerPropertyDefinitions )

Returns the data defined server properties collection found in "doc" to "dataDefinedServerProperties".

Parameters

doc	xml document
dataDefinedServerPropertyDefinitions	property collection of the server overrides

Since

QGIS 3.14

Definition at line 1389 of file qgsproject.cpp.

getVersion()

QgsProjectVersion getVersion

(

QDomDocument const &

doc

)

Returns the version string found in the given DOM document.

Returns

the version string or an empty string if none found

Note

not available in Python bindings.

removeKey_()

void removeKey_	(	const QString &	scope,
		const QString &	key,
		QgsProjectPropertyKey &	rootProperty )

Removes a given key.

Parameters

scope	scope of key
key	key name
rootProperty	is the property from which to start adding
