Detailed Description

The QColorConstants namespace contains QColor predefined constants.

\inmodule QtGui

Since
5.14

These constants are usable everywhere a QColor object is expected:

painter.setBrush(QColorConstants::Svg::lightblue);
QPainter::setBrush
void setBrush(const QBrush &brush)
Definition: qpainter.cpp:3755
QColorConstants::Svg::lightblue
constexpr QColor lightblue
Definition: qcolor.h:403
painter
QPainter painter(this)
[7]

Their usage is much cheaper than e.g. passing a string to QColor's constructor, as they don't require any parsing of the string, and always result in a valid QColor object:

\badcode object.setColor(QColor("lightblue")); // expensive
