Settings class causes an application to fail to start after it is published
-
Hi, all:
In order to prove this problem, i spent a lot of time, the situation is this:
If I use the following in any.qml file of my project:import QtCoreor
import Qt.labs.settingsstatement, after publishing my application using windeployqt.exe or windeployqt6.exe, I can't start the application, there will be no display content and console information after starting, but if I use QtCreator to start the program, it still works.
If I run my application using QtCreator, the Settings class works fine, and it correctly saves what I need to save.
Windeployqt6.exe does not add QtCore or Qt.labs.settings to the distribution folder after it is published, but I did manually and it still doesn't work.
If I don't import the QtCore or Qt.labs.settings package into my project's qml file, it will work fine again, running the released application or using QtCreator.
What both packages have in common is that they contain a class called Settings. I checked the Qt documentation, and I needed it to save my user settings.
Now, because of this problem, I have to rely on the QSettings class to complete this function.
However, if I can use the Settings class in Qml, then I think it is very convenient, because I do not need to do extra work to complete this functionality.
Qt information I use:
Qt 6.5.0
QtCreator 10.0.0

Operating System Name: Microsoft Windows 11 Pro
Operating system kernel type: Multiprocessor Free (64-bit)

@sierdzio Well, here, I use it like this, without any other options:
C:\Qt\6.5.0\msvc2019_64\bin\windeployqt6.exe appTTZDLuncher.exe
@HyEISN said in Settings class causes an application to fail to start after it is published:
without any other options:
and thats the problem, you're clearly using QML so you need to provide the path to your qml files via
--qmldir <directory>

This didn't work, and I found that--qmldir and the file I copied manually seemed to be the same. So can I ask you a question? What does the--qmldir option do when used? It's not just a simple file copy, is it? -

In fact it is usually too thorough and you can potentially reduce the folder size by removing unneeded parts, but thats there very very last step in a release process :D
