Using lrelease-pro

The lrelease-pro command line tool generates QM files from qmake projects (.pro files). It reads the TRANSLATIONS variable from the project file and generates the corresponding QM files.

Use lrelease-pro when you have a qmake project and want to generate QM files based on the translations defined in your .pro file.

lrelease-pro syntax
