@JonB Learning never stops :) I knew that these exist, but there was no connection to the word "Entity" in my mind ;-) https://www.w3schools.com/html/html_entities.asp

@ChrisW67 No, I didn't suggest this because the OP states they want every kit built for, not just every configuration.... Why, I don't know.

@Qt-embedded-developer [this] is sufficient (and better) if you only need to access class members (variables or methods) in the lambda code. [=] gives this too, but also all local variables (passed by value, not reference) in the function where the lambda is defined. It is "convenient" but "lazy". You can instead always choose explicitly to put it all local variables and/or this to pass just the specified ones, which is "better" coding style. That is what [=] does. Note that there is a similar [&] which does just the same thing but passes the local variables by reference instead.

@Daddedebad What I was expecting was for you to try disabling the virus scanner for a while and seeing if then there is no issue. In my experience some virus scanners at least open a file with exclusive access to examine it. that could cause your "file is used in another process". They tend to do this when a file is created or written to. I suppose it could also be from the Windows "copy file" itself, don't know what that does. As you seem to have discovered for yourself: you may need (a) some sort of delay, e.g. when the QFSW notifies you of change set off a timer for, say, one second to raise the signal at the end which instructs your code to read the file; and/or (b) you may have to retry opening it for read a certain number of times one second apart to allow for this, before giving up.

@kshegunov One might actually need the signal to tell us which flags have changed. Only certain flag changes affect anything we are interested in, several seem not relevant.

@ThThoma said in Detect top/parent move event on child widget: However, what if I have multiple floating widgets that track their "parent" movements? You'd have multiple event filters. And I'm answering: probably the delay from the multiple filters will start to get noticeable... I really doubt it, as long as you don't have too many. If you keep the event processing responsive, you shouldn't notice it at all. Personally, I'd rather have the window in a layout, or if it's really floating, then leave it be, but ymmv.

@AlexMax The issues is marked fixed in 6.3 and 6.4, so it it still persists in 6.5, that would probably warrant a new issue, linking to the old one. Or is it captured by linked and still-open https://bugreports.qt.io/browse/QTBUG-99602?

@Bonnie Thank you, I can't believe I didn't think of that. Now it works like a charm, thanks again!

@Chris-Kawa , Thank you. that's the solution.

@cainiao123 You might install, say, the latest version of Creator instead of one from 2017. the project in Linux virtual machine， It would be an awful lot simpler to just do the editing/development in the Linux VM, given that is what you already have....

Finally, found a solution! The trick is Not to use hover modifier/attribute for disabled items QListWidget::item:disabled, QListWidget::item:!active, {background: transparent;} This stylesheet plus removing IsEnabled or IsSelectable flag for desired items will disable hover effect.

Yinz are probly already aware of this but I think it is important to note...from the QThread documentation: The effect of the priority parameter is dependent on the operating system's scheduling policy. In particular, the priority will be ignored on systems that do not support thread priorities (such as on Linux, see http://linux.die.net/man/2/sched_setscheduler for more details).

Not sure if it will help in your case, but @hskoglund has some solution to run Qt6 on Windows 7, see here: https://forum.qt.io/topic/133002/qt-creator-6-0-1-and-qt-6-2-2-running-on-windows-7 Regarding D3D requirement, I think for widgets it should be possible to not have it (widgets are drawn using software renderer anyway). See https://doc.qt.io/qt-6/qtquick-visualcanvas-scenegraph-renderer.html#rendering-via-the-qt-rendering-hardware-interface and https://doc.qt.io/qt-6/opengl-changes-qt6.html

Hi, Did you already check the Quick Subscription example ?

Add all the modules to the target_link_libraries call.

Do you emit your signal anywhere? If not, then your slot will never be called.
