%Docstring
|
|
Encapsulates a QGIS project, including sets of map layers and their styles,
|
|
layouts, annotations, canvases, etc.
|
|
|
|
QgsProject is available both as a singleton (:py:func:`QgsProject.instance()`) and for use as
|
|
standalone objects. The QGIS project singleton always gives access to the canonical project reference
|
|
open within the main QGIS application.
|
|
|
|
.. note::
|
|
|
|
QgsProject has two general kinds of state to make persistent. (I.e., to read and
|
|
write.) First, QGIS proprietary information. Second plugin information.

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

.. seealso:: :py:func:`QgsProject.setDirty`
