Size of a QLabel with rich text

Message 1 in thread

Hi!

I want to display a little formula with a QLabel.
The formulas have the format x^a*y^b*z^c. To display the exponents I use a 
rich text with the <sup> tags.

Now the problem: The label seems to have two paragraphs or a additional 
spacing at the bottom. I attached a small pic that shows the label size.

I create the label with:
QLabel* l = new QLabel( "<qt>* x<sup>2</sup></qt>", this );
(and to show the size)
l->setFrameStyle( QFrame::WinPanel | QFrame::Sunken );

How can I remove the extra line?

Qt-version 3.0.2

You should play with setFixedHeight() and setAlignment()
The code below produces the screenshot I have attached.

Is this close to what you want??

Enjoy,
Erlend
 
#include <qapplication.h>
#include <qlabel.h>

int main( int argc, char **argv )
{
    QApplication a( argc, argv );

	QLabel* l = new QLabel( "", 0 );
    a.setMainWidget( l );

	l->setFrameStyle( QFrame::WinPanel | QFrame::Sunken );
	l->setAlignment(Qt::AlignHCenter);
	l->setAlignment(Qt::AlignLeft);
	l->setFixedHeight(20);
	l->setText("<qt>x<sup>2</sup></qt>");

    l->show();
    return a.exec();
}

Yes, that works.
