.SH "Detailed Description"
.PP 
The Thermometer Widget. 

\fBQwtThermo\fP is a widget which displays a value in an interval. It supports:
.IP "\(bu" 2
a horizontal or vertical layout;
.IP "\(bu" 2
a range;
.IP "\(bu" 2
a scale;
.IP "\(bu" 2
an alarm level.
.PP
.PP
.PP
By default, the scale and range run over the same interval of values. \fBQwtAbstractScale::setScale()\fP changes the interval of the scale and allows easy conversion between physical units.
.PP
The example shows how to make the scale indicate in degrees Fahrenheit and to set the value in degrees Kelvin: 
.PP
.nf
#include <qapplication.h>
#include <qwt_thermo.h>

double Kelvin2Fahrenheit(double kelvin)
{
    // see http://en.wikipedia.org/wiki/Kelvin
    return 1.8*kelvin - 459.67;
}

int main(int argc, char **argv)
{
    const double minKelvin = 0.0;
    const double maxKelvin = 500.0;

    QApplication a(argc, argv);
    QwtThermo t;
    t.setRange(minKelvin, maxKelvin);
    t.setScale(Kelvin2Fahrenheit(minKelvin), Kelvin2Fahrenheit(maxKelvin));
    // set the value in Kelvin but the scale displays in Fahrenheit
    // 273.15 Kelvin = 0 Celsius = 32 Fahrenheit
    t.setValue(273.15);
    a.setMainWidget(&t);
    t.show();
    return a.exec();
}
