Without registration, their properties and methods are inaccessible. +You can make C++ types from a different module available in your own module by +adding a dependency to your \l{qt_add_qml_module} call using the \e DEPENDENCIES +option. You may, for example, want to depend on QtQuick so that your QML-exposed +C++ types can use \l QColor as method arguments and return values. QtQuick +exposes \l QColor as a \l {QML Value Types}{value type} \e color. Such +dependencies may be automatically inferred at run time, but you should not rely +on this. + Also note that a number of the important concepts covered in this document are demonstrated in the \l{Writing QML Extensions with C++} tutorial. |
