Now, I need to ascertain how feasible this is to attach to other applications, after they've been compiled. Perhaps, I'll need a kind of DLL injection software.

In that case, I would use a virtual environment with the stuff specific to Qt.

See https://doc.qt.io/qt-6/supported-platforms.html#windows https://doc.qt.io/qt-6.8/windows.html https://doc.qt.io/archives/qt-6.2/windows.html

Ok. WIll try. Thank you .

I think you'd find it easier to work with this PropertyGrid instead, it supports both Qt5 / Qt6 at the same time with a very Minimal and stable API while still being very customizable

Hi and welcome to devnet, The most simple way to do it is to ask the people behind the software you are interested in.

Don't create widgets and especially layouts on the stack at all to avoid such problems.

Thank you for that hint. Maybe I'll get it figured out to get a macOS certificate for Xcode, someday, but I just don't want to spend too much effort on this. ... your link to the bug report system has the singular form not as required the plural... (just for the case you will use for other replies) ;-)

i have overridden the paint event to do what i need. thank you very much for your help! it works now

Hey, I figured out the issue! The problem was caused by building the main project inside the SuperBuild using ExternalProject_Add while also opening it in the IDE. This caused conflicts with CMake trying to reconfigure the same source twice. The fix is to build the SuperBuild separately to install dependencies, then open and build the main project separately in the IDE with SuperBuild disabled. Thanks!

Everyone who is trying to cross-compile Qt for Orange Pi 3B can follow this tutorial: https://github.com/vverenich/CrossCompileQtForOpi

Hi, You can also check out this library: 👉 QAudioTagReader It’s a Qt-friendly wrapper around TagLib for exporting audio tags.

So the solution here is not to use QRhi but the OpenGL api and setting QCoreApplication::setAttribute(Qt::AA_UseSoftwareOpenGL); to force LLVMPipe OpenGL software rendering https://doc.qt.io/qt-6/qtquick-rendercontrol-rendercontrol-rhi-example.html [image: e5a5d0e2-d829-4cd2-be6b-7bafa13d4b4b.png]

So since it's a compiler bug - what should Qt do against it?

@Sprezzatura said in What of "windowsprintersupport.dll" and "qwindowsvistastyle.dll"?: Well... why is windeployqt adding stuff that I don't need? Because it can't determine if you load these translations or not. The normal app uses translations and therefore also the ones for the Qt libs Why does the documentation mention "printsupport", yet it doesn't appear in the windeployqt output? I would guess you don't use it in your app so windeploy knows this and does not deploy it.

@Christian-Ehrlicher Ok! @everyone Another question is , how to remove one line from current list in C++? Some App such as process monitor will frequently add or remove lines in the middle of current list. However, I notice that QML List operations can only add or remove objects from the end. //qqmllist.h AppendFunction append = nullptr; CountFunction count = nullptr; AtFunction at = nullptr; ClearFunction clear = nullptr; ReplaceFunction replace = nullptr; RemoveLastFunction removeLast = nullptr; At this moment, we can clear the graph, and re-add lines. But this is not a nice solution. May be a "removeAt" function or "removeOne" can be adopted for this usage in future. There seems to be extra works for QScatterSeries and other classes from QtCharts to QtGraphs, new class has fewer functions and properties than old one. And, Will multi-Y Axises be supported in future ? For example, we can bind a line series to left axis in Kg or right axis in Meters.

If it's QML I guess a whole new Qt Quick Controls theme would be needed, and also won't take advantage of all the little details and nuances the original liquid glass has, and Qt Widgets also is its own thing right? it's not just a wrapper to call the OS native controls. Qt 6 doesn’t come with Apple’s Liquid Glass UI built in, so you’d need to design a custom Qt Quick Controls theme in QML to get the look. Even then, it won’t perfectly match all the little details of the real thing. Qt Widgets also don’t just use the OS’s native controls, so they’d need their own custom styling too.

@SGaist It should normally be like the following: [image: ef0e01c8-280c-4a6e-bada-881e471b2fba.jpg]
