PCManFM-Qt. How to change the background color?

Question

I'd like to change the background color of PCManFM-Qt, the file manager of LxQt. I now a custom stylesheet can be used with the option -stylesheet. I found the program Gammaray, a program similar to gtk-inspector. After some trying I got something working with featherpad. The css code:

#centralWidget{ background-color: red; }

works, but I cannot make red the QTextEdit widget. I don't care about featherpad, because I'd like to change the background color of PCManFM-Qt.

Answer 1

Try QTextEdit { background-color: red; }, or similiar

Qt has to know the object to which apply CSS props.
