Member Function Documentation

void QwtThermo::draw (  QPainter *    p, const QRect &    ur )  [protected]

redraw the thermo.

void QwtThermo::drawThermo (  QPainter *    p )  [protected]

Redraw the thermometer.

void QwtThermo::fontChange (  const QFont &    f )  [protected, virtual]

notify changed font.

void QwtThermo::layoutThermo (  bool    update_geometry = TRUE )  [protected]

Recalculate the thermo's geometry and layout based on.

double QwtThermo::maxValue (    )

Returns: max value.

QSize QwtThermo::minimumSizeHint (    )  const [virtual]

Return a minimum size hint. Warning: The return value depends on the font and the scale. See also: QwtThermo::sizeHint

double QwtThermo::minValue (    )

Returns: min value.

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

Qt paint event.

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

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. This function is a NOOP because margins are determined automatically.

void QwtThermo::setOrientation (  Qt::Orientation    o, ScalePos    s )

Change the thermometer's orientation. The scale position None disables the scale. Parameters: o  orientation. Possible values are Qt::Horizontal and Qt::Vertical. The default value is Qt::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.

QSize QwtThermo::sizeHint (    )  const [virtual]

Returns: the minimum size hint See also: QwtThermo::minimumSizeHint

QSizePolicy QwtThermo::sizePolicy (    )  const [virtual]

Returns: Fixed/MinimumExpanding for vertical, MinimumExpanding/Fixed for horizontal thermos.

double QwtThermo::value (    )

Returns: value.
