I recently used this to create translations files in different languages. First of all you will have to add name of files or location of files to the .pro file of your project that you want to generate TS files. After adding that you can run following:-

1. qmake -myproject.pro
2. lupdate myproject.pro This command will produces the .ts translation files listed in the project file.
3. lrelease to create qm files.

Code:

HEADERS          main-dlg.h \
                 options-dlg.h
SOURCES         main-dlg.cpp \
                  options-dlg.cpp 
 
 
FORMS              search-dlg.ui
TRANSLATIONS       search-dlg_ch.ts \      //Creates a file for chinese
