General and Desktop

Hi, One thing I could see is that setMyText is not placed under a slot directive.

That's not the problem, I can move to trash "D:\test1\test2\test3" but not "D:\test1" Subdirectory problem of QFileSystemModel ?

Please format your code!

yes, you are right. I am sure Rmdir operation cannot remove non-empty folder. I met the same issue

@SimonSchroeder Waw, this is realy helpfull (and not just a squeam in horror ;-), thank ypu! I will have a close look into your library and rework the whole lot in this way. Will take some time, but I'll give you feedback when it's done.

Hi @JoeCFD , our application supports Qt 5.6.3. Since we are not modifying the application layer, we are continuing to use version 5.6.3.

Refer to these classes for <QCamera>、<QCameraViewfinder>、<QCameraImageCapture>, which should solve your problem

My Qt 5.15.2 and 5.15.13 instances perform the same way as the Qt 6 version above. Still could be a 5.15 vs. 5.9 difference. Could it be that Qt VS Tools is not passing the include path to moc?

Not sure why I am having so many problems in something which looks very straightforward. Nothing really seems to work. [image: b0f3e8c1-3c1d-40c6-9ad7-168ea335d4db.png] The only time that I have been successful in the User Interface displaying a non-default translation language was with QLocale::setDefault. I believe that I am just going to go and try with this approach. My overall language detection logic in main.cpp is going to be something like: 0. Check if user has already explicitly set an application language If that is the case, skip to step 3 This information is going to be stored in an external configuration file outside the application. 1. Detect user's default locale with QLocale::QLocale() 2. Check if user's default locale has an available translation in the application If they do not, either do nothing else, or explicitly change the current locale to match with the default translation language (for the sake of readability) I need to think exactly how I am going to match the results but QLocale has both QLocale::language() and QLocale::name() and that should be more than enough. 3. Change default locale to expected locale using QLocale::setDefault I am not planning in adding my languages to my application. So, I am not really worried about having a big switch statement.

Hi, Is this the Qt version that comes with your distribution ? If not, can you try that one ? Did you also check with a more recent version ? 6.9 was released no too long ago.

Did you try to restart your machine once between two runs to check if it still comes up ?

@Don-Burner said in Throwing from QFuture::onFailed(): I use std::set_terminate, so unhandled exceptions call my terminate handler. EDIT: I thought std::terminate() always called std::abort(). Turns out, it calls the current terminate handler. In short, calling std::terminate() within QFuture::onFailed() works, at least for my purposes. Thanks!

Just in case, the systray example from Qt's documentation works as expected on macOS so it I think it would be good to compare the two code bases to see what is being done differently. The MacOSSysTray implementation takes quite a lot of detours to achieve the same outcome as the systray example. So I would suggest to simplify things there.
