static void _getProperties	(	QDomDocument const &	doc,
		QgsPropertyKey &	project_properties
	)

static

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

Parameters

doc	xml document
project_properties	should be the top QgsPropertyKey node.

static void _getTitle	(	QDomDocument const &	doc,
		QString &	title
	)

static

Get the project title.

XML in file has this form:

   <qgis projectname="default project">
   <title>a project title</title>

Todo:: XXX we should go with the attribute xor title, not both.

Parameters

scope	scope of key
key	key name

static

return 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 QgsPropertyKey in QgsProject:e:Imp.

Returns: null if not found, otherwise located Property

static QStringList makeKeyTokens_	(	QString const &	scope,
		QString const &	key
	)

static

Take 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.
