Hi Nyall,
The setAtlasPreviewEnabled(True) still does not work correctly. It works
exactly like the python workaround you mentioned: It toggles the atlas
button but does not activate the atlas. I mean, the prev and next
buttons stay disabled and the map does not display page number 1.
If I then, turn off and on the atlas preview, it works as expected.
Does it need to get some kind of gui redraw/update call?
Regards,
Raymond

Ok - I've done the proper approach in
https://github.com/qgis/QGIS/pull/8170/files
(I've also exposed an API call to show the item properties for a
particular item)
Let me know if there's anything else you think should be exposed from
the designer to the designer API.
Nyall
# open layout
designer = iface.openLayoutDesigner(layout)
# turn on atlas preview mode
lo_view = designer.view()
lo_window = lo_view.window()
action = lo_window.findChild(QAction, 'mActionAtlasPreview')
action.toggle()

Hi Nyall,
It sounded great and I spent some hours on that better approach, but I
didn't succeed. So maybe 3.6 will have it...
Tnx!

You'd have to do some fragile code to do this. Basically:
- get designer window from designer.view()'s parent window
- find the mActionAtlasPreview child action in the window
- manually toggle it on
This should work, but isn't stable API - so is likely to break ;)
A better approach is to (quickly, before 3.4 final!) file a PR
exposing the toggle atlas preview behavior to
QgsLayoutDesignerInterface. Then you'll be able to just do:
designer = iface.openLayoutDesigner( layout )
designer.toggleAtlasPreview( True )
Nyall
Hope anyone knows!
Kind regards,
Raymond
