SPAM, Re: dark theme ?

[Detlev Offenbach]

Hello,

using a dark qt5ct theme with a light desktop theme doesn't give me dark 
colored eric6. However, if I switch the desktop theme to a dark theme 
(e.g. Breeze Dark) every Qt widget in eric uses this dark colors. I did 
not find a reason, why qt5ct does not work as expected. Testing it with 
native Qt application (Qt Designer) showed the same behavior like eric6. 
Therefore I assume, it is Qt ignoring qt5ct.

An alternative would be to create a QSS style file. The eric archive 
includes an example called 'Chinese_Dark.qss' located in the 'styles' 
folder.

Regards,
Detlev
