.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
The fill colors might be calculated from an optional color map If no color map has been assigned \fBQwtThermo\fP uses the following colors/brushes from the widget palette:
.PP
.IP "\(bu" 2
QPalette::Base Background of the pipe
.IP "\(bu" 2
QPalette::ButtonText Fill brush below the alarm level
.IP "\(bu" 2
QPalette::Highlight Fill brush for the values above the alarm level
.IP "\(bu" 2
QPalette::WindowText For the axis of the scale
.IP "\(bu" 2
QPalette::Text For the labels of the scale
