My program doesn't show up in my enterprise device while in pc does

What did you have to switch ?

@SGaist
Hello, look up posts #2 and #4. He had switched:

 connect(my_combobox, SIGNAL(currentIndexChanged(int)), this, SLOT(SetSomeLabels(int)));
 LoadXMLInfo();

to make it work, although I see no logical reason not to work in the original order.

SGaist

I also don't see any reason either.

However, one thing I usually do is to setup widgets and connection and then trigger data/settings loading once everything is done or even right after the event loop as started using e.g. a QTimer with a 0 timeout.

@SGaist
To be honest I've never found any use for single shot timers with 0 timeout. Although, this depends on a personal preference I have always used QMetaObject::invokeMethod with Qt::QueuedConnection for such purposes. :)

SGaist

QTimer is higher level and a bit clearer for people not going in the lower levels of Qt. But in the end, yes both have the same effects.

Also, invokeMethod doesn't have any overload for lambdas

True, however you can pass arguments with it. And lambdas I can't remember needing really. ;)

SGaist

Yup, good point.

For lambdas ? Two main things comes to mind for Qt: real private slots and processing of QNetworkReply :)

Q_PRIVATE_SLOT works wonders for me, although I could appreciate one wanting to use lambdas for it. QNetworkReply I've never used, only raw TCP/UDP connections ... I guess, I'm pretty old school ... :)

AFAIK, works only if you also use the PIMPL idiom, which is not the most common case.

QNetworkAccessManager is a good tool when you want to write a layer to access a REST service. You use what best fits your needs :)

wow! I've learned a lot with this little conversation, thank you so much! (Even if i don't understand everything but I'll take a look on it calmly later :D)

@kshegunov I'm not "he" , I'm "she" ;) but don't worry haha

I think I'll close this topic as I see that what happened is not normal but is difficult to know why happened so, don't worry about that :) (and of course because I have to move on and finish what I'm doing )

Thank you @SGaist and @kshegunov ^^

I'm sorry, unfortunately there's almost no way to deduce that in English, so please allow amicably for such misunderstandings ... :)

Kind regards.
