I have created 3 print layouts in QGIS3. Now I am trying to get a list of all layouts in the LayoutManager with python. This is how I am trying to do it(this code is executed in the python console of QGIS3):

>>> from qgis.core import QgsLayoutManager
>>> layoutmanager = QgsLayoutManager()
>>> layoutmanager.layouts()
>>> []

What I get is an empty list. So what am I missing? Do I have to save the Layouts in a special way? For those who don't understand what I mean with layout, in QGIS3 Layout is the new Composer.


With your code, you are creating a new instance of QgsLayoutManager. So, you don't get current list but an empty one.

You should retrieve the project instance with

projectInstance = QgsProject.instance()

From it, you can get the current layoutManager instance and deduce the layouts

projectLayoutManager = projectInstance.layoutManager()


If you are not aware of it, the new Python API docs really helped https://qgis.org/pyqgis/master/core/QgsProject.html

  • Yeah thanks, I wasn't aware that there is a new Python API. – Blinxen Jan 22 '18 at 10:38
  • In fact, it's the docs for Python API who is new not the Python API itself (only some changes compared to QGIS 2.x version) – ThomasG77 Jan 22 '18 at 10:43
