Description

This variable is set to ON by default in the Qt Quick Ultralite core library.

It enables StdStringType typedef and enables you to construct String with a std::string parameter or StdStringType parameter.

Disabling QUL_STD_STRING_SUPPORT saves flash memory. To disable it in the Qt Quick Ultralite core library, rebuild the core library with QUL_STD_STRING_SUPPORT=OFF. For more information, see Building Qt Quick Ultralite from sources.

When it is set to OFF in the Qt Quick Ultralite core library, the application CMakeLists can set it to ON to enable StdStringType typedef usage in the application code only.

Since

This variable was introduced in Qt Quick Ultralite 2.12.
