Reading CSS property from C++ code

[peter-70]

As the title suggests, I would like to know if it is possible to read CSS properties or attributes from my C ++ code.Thanks for your tips!

For (abstract) example:

QVariant getValue(QWidget* widget, const QString& propertyName)
{
    return widget->style()->getValue(propertyName);
}

Hi
You would have to parse the stylesheet yourself.
There is no API for it. sadly.
You could look at Qt source for its cssparser or
be inspired from

There's plenty of libraries available that can parse CSS, for example: https://github.com/lexborisov/mycss

Ok, but there is not any Qt's own functionality to do that? I know, I can parse the styleSheet, but when Qt were able to giving me what I'm searching for, it could be surly the better way to solve this problem (...I think)

That's why the answers are saying that there is not such an inbuilt Qt API for this....

@JonB said in Reading CSS property from C++ code:

Irrelevant note: there is (it's the one Qt uses to read style sheets applied to widgets) but it's not exposed to the external users, it's private to the libraries

@VRonin
Yes, that's what I meant, as per @mrjj's

You could look at Qt source for its cssparser

On this note, are you a person to consider whether Qt might like to expose this at a future date? Qt offers offers so much miscellaneous useful stuff, it might be a nice addition....
