void QwtThermo::paintEvent ( QPaintEvent * e ) [protected]

Qt paint event handler.

void QwtThermo::resizeEvent ( QResizeEvent * e ) [protected]

Qt resize event handler.

void QwtThermo::scaleChange ( ) [protected, virtual]

notify changed scale. Reimplemented from QwtScaleIf.

void QwtThermo::setAlarmColor ( const QColor & c )

Specify liquid color above the alarm threshold. Parameters: c   New color. The default is white.

void QwtThermo::setAlarmEnabled ( int tf )

Enable or disable alarm threshold. Parameters: tf   ZERO (disabled) or non-zero (enabled)

void QwtThermo::setAlarmLevel ( double v )

Specify the alarm threshold.

void QwtThermo::setBorderWidth ( int w )

Set the border width of the pipe.

void QwtThermo::setFillColor ( const QColor & c )

Change the color of the liquid. 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.

void QwtThermo::setOrientation ( Orientation o, 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

void QwtThermo::setValue ( double v ) [slot]

Set the current value.
