Parameters:
c  New color. The default color is black.

void QwtThermo::setMargin int    m
 

Specify the distance between the pipe's endpoints and the widget's border.

The margin is used to leave some space for the scale labels. If a large font is used, it is advisable to adjust the margins.

Parameters:
m  New Margin. The default values are 10 for horizontal orientation and 20 for vertical orientation.
Warning:
The margin has no effect if the scale is disabled.

ScalePos    s
 

Change the thermometer's orientation.

The scale position None disables the scale.

Parameters:
o  orientation. Possible values are Horizontal and Vertical. The default value is Vertical.
s  Position of the scale. For a horizontal orientation, the scale position can be Top, Bottom or None. A vertical thermometer may have the scale positions Left, Right or None. The default is None.

void QwtThermo::setPipeWidth int    w
 

Change the width of the pipe.

void QwtThermo::setRange double    vmin,
double    vmax
 

Set the range.

Parameters:
vminValue  corresponding lower or left end of the thermometer
vmax  Value corresponding to the upper or right end of the thermometer
