Good way to maintain Qt labels and text on UI

What is the best way/common practice for maintaining all string resources found on a UI in Qt, especially the textual input/text in combo boxes etc. (since these are the once that are frequently used in the code itself)?

I know that Android has this string resources thing such that resources only have to be modified at one position.

Does Qt have something like that too or do I have to initialize string resources in code instead of in the UI's XML itself...

There is a mechanism to dynamically translate texts in application, but it works a bit different than Android string resources, but achieves the same goals.

Qt uses i18n system modelled after standard, well known unix gettext. It works in a very similar way to iOS NSLocalizedString, if that rings a bell.

http://doc.qt.io/qt-5/qobject.html#tr

This is worth reading too:

Android approach is a bit unique and you should not expect it to be a "standard everywhere". It works, it's ok, but it's not a standard way of doing things on desktop.

AFAIK, there is no built-in mechanism for string resources in Qt. If you want to maintain strings at build time you can define them in one .h/.cpp file as global variables and reuse them in your code.

Otherwise you can use Qt's translator files (binary) and load them along with your application. If you need to change a string, you simply will need to edit the translation file (xml) and "recompile" it with lrelease utility without building the application again.
