Function Documentation

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:
docxml document
project_propertiesshould 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.

static QgsProjectVersion _getVersion ( QDomDocument const &  doc) [static]

return the version string found in the given Dom document

Returns:
the version string or an empty string if none found

) [static]

return the property that matches the given key sequence, if any

Parameters:

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.
