here's my problem: I'm using Qt, I've got two QLineEdits (name, author) and one QTextEdit (description) in my form. I need to set placeholders for each of them, so i wrote this code:

        name->setPlaceholderText("Name");
        author->setPlaceholderText("Author");
        description->setPlaceholderText("Description");

Now I want to style it using QSS, thus i wrote this:

    QLineEdit[text=""],
    QTextEdit[text=""] {
      color: red;
    }

But unfortunately this works only for QLineEdits and I cannot find a way to check if QTextEdit is empty in QSS. Do you have any idea? Thanks in advance.
