[Qt-interest] QLabel color with dark themes

[Jay L. T. Cornwall]

Hi,

I use Qt with the qgtkstyle plugin to adopt the GTK theme. With GTK I 
use the Moomex Ultimatum theme which is largely white text on black 
backgrounds.

In my Qt application I construct a QLabel and add it to a QStatusBar. 
This label correctly appears in white. However, if I construct a QLabel 
and add it to a QHBoxLayout, which itself is inside a QMainWindow, the 
text appears in black and cannot be read.

Using the text '<font color="white">Test</font>' makes this label appear 
in white. Why do the colour schemes of the two labels differ according 
to their context? Does Qt have a default stylesheet which makes this so?

(I am aware that dark themes are quite troublesome in Linux.)
