class QgsProject : QObject, QgsExpressionContextGenerator, QgsProjectTranslator
{
%Docstring
Reads and writes project states.

\note

Has two general kinds of state to make persistent.  (I.e., to read and
write.)  First, QGIS proprietary information.  Second plug-in information.

A singleton since there shall only be one active project at a time; and
provides canonical location for plug-ins and main app to find/set
properties.
%End

%TypeHeaderCode

  public:
    static QgsProject *instance();
%Docstring
Returns the QgsProject singleton instance
%End

    explicit QgsProject( QObject *parent /TransferThis/ = 0 );
%Docstring
Create a new QgsProject.

Most of the time you want to use QgsProject.instance() instead as many components of QGIS work with the singleton.

    ~QgsProject();

    void setTitle( const QString &title );
%Docstring
Sets the project's title.

   The use of this method is discouraged since QGIS 3.2 as it only works with project files stored

   replacements that are aware of the fact that projects may be saved in other project storages.

class QgsProjectDirtyBlocker
{
%Docstring
Temporarily blocks QgsProject "dirtying" for the lifetime of the object.

QgsProjectDirtyBlocker supports "stacked" blocking, so two QgsProjectDirtyBlockers created
for the same project will both need to be destroyed before the project can be dirtied again.

Note that QgsProjectDirtyBlocker only blocks calls which set the project as dirty - calls
which set the project as clean are not blocked.

Python scripts should not use QgsProjectDirtyBlocker directly. Instead, use :py:func:`QgsProject.blockDirtying()`
.. code-block:: python

       project = QgsProject.instance()
       with QgsProject.blockDirtying(project):
         # do something
