QColorConstants Namespace

The QColorConstants namespace contains QColor predefined constants. More...

Header: #include <QColorConstants>
CMake: find_package(Qt6 REQUIRED COMPONENTS Gui)
target_link_libraries(mytarget PRIVATE Qt6::Gui)
qmake: QT += gui

Detailed Description

These constants are usable everywhere a QColor object is expected:

painter.setBrush(QColorConstants::Svg::lightblue);

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:

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