QLatin1Constant Class Reference

Macro Documentation

Q_DECLARE_LATIN1_CONSTANT

This macro, along with the related Q_DEFINE_LATIN1_CONSTANT macro, allows you to describe a "Latin 1 string constant".

The resulting constant can be passed to functions accepting a QLatin1String, a QString, or a QVariant.

The first parameter is the name of the variable to declare. The second parameter is the value of the constant, as a string literal.

For example:

 // in a header file
 Q_DECLARE_LATIN1_CONSTANT(MyConstant, "MYCONSTANT");

The declaration should be paired with a matching Q_DEFINE_LATIN1_CONSTANT with the same arguments to actually define the constant.

See also Q_DEFINE_LATIN1_CONSTANT.

Q_DEFINE_LATIN1_CONSTANT

This macro, along with the related Q_DECLARE_LATIN1_CONSTANT macro, allows you to describe a "Latin 1 string constant".

The resulting constant can be passed to functions accepting a QLatin1String, a QString, or a QVariant.

The first parameter is the name of the variable to define. The second parameter is the value of the constant, as a string literal.

For example:

 // in a header file
 Q_DECLARE_LATIN1_CONSTANT(MyConstant, "MYCONSTANT");

 // in source file
 Q_DEFINE_LATIN1_CONSTANT(MyConstant, "MYCONSTANT");

You can use this macro without the matching DECLARE macro if you are using the constant only in a single compilation unit.
