# Qt5 module |
|
|
|
The Qt5 module provides tools to automatically deal with the various |
|
tools and steps required for Qt. The module has two methods. |
|
|
|
## preprocess |
|
|
|
This method takes the following keyword arguments: |
|
- `moc_headers`, `moc_sources`, `ui_files`, `qresources`, which define the files that require preprocessing with `moc`, `uic` and `rcc` |
|
- `include_directories`, the directories to add to header search path for `moc` (optional) |
|
- `moc_extra_arguments`, any additional arguments to `moc` (optional). Available since v0.44.0. |
|
|
|
It returns an opaque object that should be passed to a main build target. |
|
|
|
## compile_translations (since v0.44.0) |
|
|
|
This method generates the necessary targets to build translation files with lrelease, it takes the following keyword arguments: |
|
- `ts_files`, the list of input translation files produced by Qt's lupdate tool. |
|
- `install` when true, this target is installed during the install step (optional). |
|
- `install_dir` directory to install to (optional). |
|
- `build_by_default` when set to true, to have this target be built by default, that is, when invoking plain ninja; the default value is false (optional). |
|
|
|
## Example |
|
A simple example would look like this: |
|
|
|
```meson |
|
qt5 = import('qt5') |
|
qt5_dep = dependency('qt5', modules: ['Core', 'Gui']) |
|
inc = include_directories('includes') |
|
moc_files = qt5.preprocess(moc_headers : 'myclass.h', |
|
moc_extra_arguments: ['-DMAKES_MY_MOC_HEADER_COMPILE'], |
|
include_directories: inc) |
|
translations = qt5.compile_translations(ts_files : 'myTranslation_fr.ts', build_by_default : true) |
|
executable('myprog', 'main.cpp', 'myclass.cpp', moc_files, |
|
include_directories: inc, |
|
dependencies : qt5_dep) |
|
``` |
|
|
|
|
|
The 'modules' argument is used to include Qt modules in the project. |
|
See the Qt documentation for the [list of modules](http://doc.qt.io/qt-5/qtmodules.html). |
|
|
|
## private headers (since v0.47.0) |
|
|
|
Some projects needs Qt's private headers to build, that's why a **private_headers** keyword argument has been added to [dependency](Reference-manual.md#dependency) method. |
|
Setting this optionnal argument will add private include path of the given module to the compiler flags. |
|
Note that this option is only compatible with qmake dependency method, using auto or pkg-config will fallback to qmake.
