# Qt5 module The Qt5 module provides tools to automatically deal with the various tools and steps required for Qt. The module has one method. ## preprocess This method takes four keyword arguments, `moc_headers`, `moc_sources`, `ui_files` and `qresources` which define the files that require preprocessing with `moc`, `uic` and `rcc`. It returns an opaque object that should be passed to a main build target. A simple example would look like this: ```meson qt5 = import('qt5') qt5_dep = dependency('qt5', ...) moc_files = qt5.preprocess(moc_headers : 'myclass.h') executable('myprog', 'main.cpp', 'myclass.cpp', moc_files, dependencies : qt5_dep) ```
