HTML fails in Qt QLabel

When using a QLabel element filled with some html text, I have a problem: it does not simply render the HTML, it inserts some space around the html text.

The following renders ok:

A simple text!开发者_如何学Go

The following fails:

A <strong>HTML</strong> text!

Actually, Qt renders everything okay, but always I have html in my text, there are some space around my text, however, in my application, this space becomes a real problem. All CSS I've tried fails, maybe I just do not know the exactly way to style it.

Are you setting the text using setText() function? If you pass a QString which contains rich text in setText() parameter, the rich text is supposed to be rendered. If not, you can try to set the QLabel's textFormat to Qt::RichText.

I just tried this code and it's working.

   #include <QApplication>
    #include <QLabel>
    int main(int argc, char *argv[])
    {
    QApplication app(argc, argv);
    QLabel *label = new QLabel("<strong>Hello</strong> "
    "<font color=red>Wanderson !");
    label->show();
    return app.exec();
    }
