I've been trying to use the themes options in QGIS.

In the window mode they work just quite well and layer format changes.

Themes in QGIS window

But when I go to the layout print menu the themes show up but it keeps defaulting back to the first theme.

QGIS Layout

My question is, Is there a way to different themes in the layout window or have I missed a step.

I suspect it's a bug in QGIS - I'm using Version 3.10.

  • Hm, I'm using 3.10, and whenever I check "Follow map theme" and change the theme, the map content change accordingly. In my case only "Follow map theme" is checked, not "Lock layers" and "Lock styles for layers". – 9ls1 Mar 18 at 7:05
  • I tried only use "Follow map theme" - Same result happens. Maybe I'll have to try it again with a new work space – Garth Cooper Mar 18 at 7:20
  • why (in your last screenshot) is follow map theme unchecked ? it doesn't seem logical knowing what's your aim ... i don't see how this would work in that case. with this checkbox left unchecked i suppose the two others options (lock layers and lock styles) override any selection you made in follow map theme (imho) – snaileater Mar 18 at 7:29

    QGIS doesn't let you chose both "Follow Map Theme" and Lock layers. It's one or the other. Not sure why. Tried all possible combinations and got the same result. – Garth Cooper Mar 18 at 8:05
  • Why would you like to check both? It's enough with "Follow map theme" checked. The map content changes accordingly with the chosen map theme in 3.10. – 9ls1 Mar 18 at 8:21
