I can't remember what it means when there are objects,variables stated between a Classes name and the opening brace. An example of what I mean is shown below (taken from the Qwt code) and emboldened.
Code:
AttitudeIndicator::AttitudeIndicator(
QWidget *parent):
QwtDial(parent),
d_gradient(0.0)
{
setMode(RotateScale);
setWrapping(true);
setOrigin(270.0);
setScaleOptions(ScaleTicks);
setScale(0, 0, 30.0);
//setRange(0.0,360.0,1.0,1.0);
const QColor color =
#if QT_VERSION < 0x040000
colorGroup().text();
#else
palette().color(QPalette::Text);
#endif
setNeedle(new AttitudeIndicatorNeedle(color));
}
Could someone tell me what it means to have the lines as shown ?
