AUTOUIC
|
|
|
|
|
-------
|
|
|
|
|
|
|
|
|
|
Should the target be processed with auto-uic (for Qt projects).
|
|
|
|
|
|
|
|
|
|
:prop_tgt:`AUTOUIC` is a boolean specifying whether CMake will handle
|
|
|
|
|
the Qt ``uic`` code generator automatically, i.e. without having to use
|
|
|
|
|
commands like :module:`QT4_WRAP_UI() <FindQt4>`, ``QT5_WRAP_UI()``, etc.
|
|
|
|
|
Currently, Qt versions 4 to 6 are supported.
|
|
|
|
|
|
|
|
|
|
This property is initialized by the value of the :variable:`CMAKE_AUTOUIC`
|
|
|
|
|
variable if it is set when a target is created.
|
|
|
|
|
|
|
|
|
|
When this property is ``ON``, CMake will scan the header and source files at
|
|
|
|
|
build time and invoke ``uic`` accordingly.

|

Header and source file processing
|
|
|
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
|
|
|
|
|
|
At build time, CMake scans each header and source file from the
|
|
|
|
|
target's sources for include statements of the form
|
|
|
|
|
|
|
|
|
|
.. code-block:: c++
|
|
|
|
|
|
|
|
|
|
#include "ui_<ui_base>.h"
|
|
|
|
|
|
|
|
|
|
Once such an include statement is found in a file, CMake searches for the
|
|
|
|
|
``uic`` input file ``<ui_base>.ui``
|
|
|
|
|
|
|
|
|
|
- in the vicinity of the file and
|
|
|
|
|
- in the :prop_tgt:`AUTOUIC_SEARCH_PATHS` of the target.
|
|
|
|
|
|
|
|
|
|
If the ``<ui_base>.ui`` file was found, ``uic`` is called on it to generate
|
|
|
|
|
``ui_<ui_base>.h`` in the directory
|
|
|
|
|
|
|
|
|
|
- ``<AUTOGEN_BUILD_DIR>/include`` for single configuration generators or in
|
|
|
|
|
- ``<AUTOGEN_BUILD_DIR>/include_<CONFIG>`` for
|
|
|
|
|
:prop_gbl:`multi configuration <GENERATOR_IS_MULTI_CONFIG>` generators.
|
|
|
|
|
|
|
|
|
|
Where ``<AUTOGEN_BUILD_DIR>`` is the value of the target property
|
|
|
|
|
:prop_tgt:`AUTOGEN_BUILD_DIR`.
|
|
|
|
|
|
|
|
|
|
The include directory is automatically added to the target's
|
|
|
|
|
:prop_tgt:`INCLUDE_DIRECTORIES`.

Modifiers
|
|
|
|
|
^^^^^^^^^
|
|
|
|
|
|
|
|
|
|
:prop_tgt:`AUTOUIC_EXECUTABLE`:
|
|
|
|
|
The ``uic`` executable will be detected automatically, but can be forced to
|
|
|
|
|
a certain binary using this target property.
|
|
|
|
|
|
|
|
|
|
:prop_tgt:`AUTOUIC_OPTIONS`:
|
|
|
|
|
Additional command line options for ``uic`` can be set via this target
|
|
|
|
|
property. The corresponding :prop_sf:`AUTOUIC_OPTIONS` source file property
|
|
|
|
|
can be used to specify options to be applied only to a specific
|
|
|
|
|
``<base_name>.ui`` file.
|
|
|
|
|
|
|
|
|
|
:prop_sf:`SKIP_AUTOUIC`:
|
|
|
|
|
Source files can be excluded from :prop_tgt:`AUTOUIC` processing by setting
|
|
|
|
|
this source file property.
|
|
|
|
|
|
|
|
|
|
:prop_sf:`SKIP_AUTOGEN`:
|
|
|
|
|
Source files can be excluded from :prop_tgt:`AUTOMOC`,
|
|
|
|
|
:prop_tgt:`AUTOUIC` and :prop_tgt:`AUTORCC` processing by
|
|
|
|
|
setting this source file property.
|
|
|
|
|
|
|
|
|
|
:prop_gbl:`AUTOGEN_TARGETS_FOLDER`:
|
|
|
|
|
This global property can be used to group :prop_tgt:`AUTOMOC`,
|
|
|
|
|
:prop_tgt:`AUTOUIC` and :prop_tgt:`AUTORCC` targets together in an IDE,
|
|
|
|
|
e.g. in MSVS.
|
|
|
|
|
|
|
|
|
|
:variable:`CMAKE_GLOBAL_AUTOGEN_TARGET`:
|
|
|
|
|
A global ``autogen`` target, that depends on all :prop_tgt:`AUTOMOC` or
|
|
|
|
|
:prop_tgt:`AUTOUIC` generated ``<ORIGIN>_autogen`` targets in the project,
|
|
|
|
|
will be generated when this variable is ``ON``.
|
|
|
|
|
|
|
|
|
|
:prop_tgt:`AUTOGEN_PARALLEL`:
|
|
|
|
|
This target property controls the number of ``moc`` or ``uic`` processes to
|
|
|
|
|
start in parallel during builds.
