That's exactly what ends up happening when you call your QFileDialog
with setMimeTypeFilters, the filters will be constructed out of
QMimeType.

Just a guess but many application might not succeed in finding their
MIME type in the db. They could provide an XML file for that, but this
is quite a hassle compared to just writing a few characters. Also how
can several mime types be represented? Like your example "C++
sources;;Allfiles".

system, as is the case on most Windows, OS X, and iOS systems, Qt will
use its own copy of it."
While this does not sound too bad, it at least gives the impression of
a not too well working process.

Thank you for thinking about the translators. :)
I did not know about QMimeDatabase until now. On my system I have 930
MIME types in the db. Just for you to compare with yours.
To me this looks like a nice way to have unified strings for file
types and I would also like to know if there are things speaking
against using it.

File dialog filters
Hi,
I noticed that in KMyMoney the filter strings for file dialogs are created "by
hand", e.g. i18n("C++ sources (*.cpp *.cxx *.c++);;All files (*)"). So each of
them must be translated. Alternatively something like
QMimeDatabase db;
db.mimeTypeForName("text/x-c++src").filterString()
could be used to create these string lowering the burden on the translators
and resulting in consistent translations for all mimetypes.
Do we have a policy regarding this? Are there any drawbacks? Can it happen
that the mimetype database does not include all files on some systems?
I know there is QFileDialog::setMimeTypeFilters() where the mimetype can be
set directly, but this does not work with the static functions.
Greetings
Christian
