Set QFrame frame style with QSS

[Neph]

Hi,

I (Qt 5.15.13 and Python 3.12.12) am currently working on a layout that uses a QFrame to create a border around another layout or a line between two layouts.

I know that you can set the design of the QFrame, as shown in the image in the documentation with e.g. qframe.setFrameStyle(QFrame.Box | QFrame.Plain) and the border's thickness with qframe.setLineWidth(3).

I also know that you can alternatively use QSS to set the border thickness and even the color:

qframe.setStyleSheet("QFrame#myqframe {border: 1px solid red}")

Now I'm wondering: Is it also possible to set the actual frame style using only QSS? I tried this but it didn't work (didn't display anything):

qframe.setStyleSheet(
"QFrame#myqframe {"
    "frameShape: box;"
    "frameShadow: raised"
    "border: 3px solid black"
"}")

The reference for QT stylesheets is at https://doc.qt.io/qt-6/stylesheet-reference.html. You will find QFrame listed there. When you follow the links you get to see all the attributes Qt supports. So far as I know neither frameShape nor frameShadow are supported, and similarly for most others --- Qt only supports very limited subset of the most common ones.

@JonB Thanks for the link! There's border-radius, which makes the plain "StyledPanel" style possible but the website only mentions a shadow for "PaletteRole". Does this mean that you can't achieve the "raised" or "sunken" styles purely using QSS?
