- \class QxtProgressLabel QxtProgressLabel
- \ingroup QxtGui
- \brief A label showing progress related time values.
-
- QxtProgressLabel is a label widget able to show elapsed and remaining
- time of a progress. Usage is as simple as connecting signal
- \b QProgressBar::valueChanged() to slot QxtProgressLabel::setValue().
-
- Example usage:
- \code
- QProgressBar* bar = new QProgressBar(this);
- QxtProgressLabel* label = new QxtProgressLabel(this);
- connect(bar, SIGNAL(valueChanged(int)), label, SLOT(setValue(int)));
- \endcode
