Nightly builds / Re: The 27 May 2026 build (13855) is out.
« Last post by cacb on September 01, 2026, 12:13:31 pm »Thank you for the answer. On Kubuntu, the option under Environment -> Colours, i.e. "Select application appearance (if supported by platform)" is disabled, so I am not able to select anything. It says "System Default" only.
Thank you for the clarification of the missing dark mode in the editor window. That is a pity, but at least it is clear.
EDIT: Given no support for dark mode in the editor, I have been looking for a way to change the main background colour of the editor window to something other than white. This is not a perfect solution, but it may give some eye relief: Settings -> Editor -> Syntax highlighting
Then select something other than pure white as background, for example light blue (H,S,L) = (140,240,200).
EDIT2: On closer inspection, it is possible to achieve a decent dark mode in the editor using Settings -> Editor -> Syntax highlighting and creating a new "Colour theme" called e.g. DarkMode and change all the relevant colours including foreground/background and C++ language related colours, I did this and copied the relevant section of default.conf from Windows to Linux so now I have a working dark mode of both the C::B IDE and the code editor. At least it seems good enough to try to use it. This means to switch from default to dark mode or vice versa you have to do 2 things
Settings -> Environment -> Colours "Select application appearance (if supported by platform)" (or use environment variable as needed)
Settings -> Editor -> Syntax highlighting Select the relevant user defined colour theme.
