Hi, Danny.
Using widget palettes and style sheets together is not actually
supported by Qt, so there will be some inconsistencies when trying to do
this.
In your case what is happening is that the style sheet is preventing the
palette from being propagated from the list view to its viewport, hence
the viewport will not turn red, only the frame around it. To work around
it in your specific case, you can use the following code:
ui.lst.viewport().setPalette(RED_QPALETTE);
Please note, however, that since this is documented to be an unsupported
combination of two styling models, there is no guarantee that the
behavior will not change in later versions.
