\target qt6_target_compile_qml_to_cpp
\brief Compiles QML files (.qml) to C++ source code with \l{Qml Type Compiler}{qmltc}.
\section1 Synopsis
\badcode
qt_target_compile_qml_to_cpp(
target
QML_FILES ...
[NAMESPACE namespace]
[IMPORT_PATHS ...]
)
\endcode
\versionlessCMakeCommandsNote qt6_target_compile_qml_to_cpp()
\section1 Description
By default, \l{Qml Type Compiler}{qmltc} creates lower-case \c{.h} and \c{.cpp}
files for a given \c{.qml} file. For example, \c{Foo.qml} ends up being compiled
into \c{foo.h} and \c{foo.cpp}.
The created C++ files are placed into a dedicated \c{.qmltc/<target>/}
sub-directory of the \c BINARY_DIR of the \c target passed as an argument to
this command. These files are then automatically added to the target sources and
compiled as Qt C++ code along with other source files.
\note This command is in technology preview and may change in future releases.
\section1 Arguments
The \c target specifies the name of the binary that the QML files belong to. In
order for the compilation to succeed, the target is expected to be a valid QML
module, defined with qt_add_qml_module() command.
\c QML_FILES lists the \c{.qml} files that are going to be compiled into C++. In
most cases, all the target's QML files would be specified in the QML_FILES. This
way, QML_FILES argument of this command is equivalent to QML_FILES argument of
the qt_add_qml_module() command.
\c NAMESPACE argument defines a namespace, in which the generated C++ code
resides. By default, no namespace is specified for user projects. The code
generated from Qt's own sources is put under a QT_NAMESPACE namespace.
\c IMPORT_PATHS can be used to add locations that contain QML modules. The
specified entries are passed to qmltc and allow to correctly import modules that
do not reside under the location specified by QLibraryInfo::QmlImportsPath.
While processing QML_FILES, the following source file properties are respected:
\list
\li \c{QT_QMLTC_FILE_BASENAME}: use this source file property to specify a
non-default .h and .cpp file name, which might be useful to e.g. resolve
conflicting file names (imagine you have main.qml that is being
compiled, but main.h already exists, so #include "main.h" might not do
what you expect it to do). QT_QMLTC_FILE_BASENAME is expected to be a
file name (without extension), so any preceding directory is ignored.
Unlike in the case of default behavior, the QT_QMLTC_FILE_BASENAME is
not lower-cased.
