Unsolved Lost QTableWidget's ability to use StyleSheet

[Driftwood]

I have a QTableWidget (Qt Creator 4.14.2) that refuses to be styled. This is the code I'm using, code that worked like a charm last year when I was using Qt. But now, it's dead.

 ui->tableWidget_Customers->setStyleSheet("alternate-background-color: #d3eaea;");
 ui->tableWidget_Customers->horizontalHeader()->setStyleSheet
    ("QHeaderView::section { color: white; background-color:teal }"); 
 ui->tableWidget_Customers->verticalHeader()->setStyleSheet
    ("QHeaderView::section { color: white; background-color:teal }");

I've noticed this about Qt: If it works today, just wait for tomorrow and it won't. They have a knack of "fixing" what isn't broken.

Hi,

Which version of Qt are you using exactly ?
Can you provide a minimal compilable example that shows that behaviour ?

[Driftwood]

@SGaist - This is what I have:

{noformat}
Qt 5.15.2 (x86_64-little_endian-lp64 shared (dynamic) release build; by GCC 5.3.1 20160406 (Red Hat 5.3.1-6)) on "xcb" 
OS: Linux Mint 20.2 [linux version 5.4.0-80-generic]

Environment:
  QT_ACCESSIBILITY="1"
  QT_QPA_PLATFORMTHEME="qt5ct"

Features: QT_NO_EXCEPTIONS

If needed, I'll create a minimal-usage scenario.

Yes a minimal compilable example will be a good thing.

Are you using your distribution provided Qt or one that you installed using the online installer ?

[Driftwood]

@SGaist - I got it from the Qt website. When I installed it, I watched it use my default Qt e-mail address and password before downloading myriad files.

As for the minimal asking, I just determined this isn't a Qt issue. Let me explain.

I don't use Qt's editor. I use CLion instead. When I run this in Qt (which I never do), the styling works fine. However, when I run it in CLion, the app takes on my system-wide theme. So I'm thinking this may be a CLion issue, since the styling works perfectly when I run the app out of Qt Creator. I hate days like this :D
