[Interest] Questions regarding "Improper Link Resolution Before File Access in QFileSystemEngine"

Hi! Regarding CVE-2025-4211, “Improper Link Resolution Before File Access in QFileSystemEngine”, could someone elaborate what public APIs are affected? The mentioned QFileSystemEngine is not a public API, so which public APIs use it internally? Since the issue mentions GetTempPath, which sounds

[Interest] How to make QMap work as input to std::ranges::views?

I have tried and failed, please see https://godbolt.org/z/9zTzP7sYj It looks like QMap::asKeyValueRange returns something that is not really understood as a range, or not one that views can use. How can I use a QMap as input to a std::ranges::views pipeline? Kind regards Robert

[Interest] Issues with QML registration of C++ types (only in Visual Studio Solution)

My project contains QML files that will refer to C++ types by name. The QML module and type are registered on startup, the QML file does the right import(s), then I can use C++ classes (QObjects with QML_ELEMENT) as typed entities in QML. Everything works as expected….when using cmake. The same

Re: [Interest] Extension modules: Is there some documentation?

Hi! It would still be nice to know what the deployment strategies are going to be. It looks like the extension modules are named by Qt version, so there are extension modules for 6.8.2 and 6.9.0. If there is a critical vulnerability, what happens? Will I get a patched extension modules for 6.8.

[Interest] Extension modules: Is there some documentation?

Hi! I recently switched to 6.8.2 and noticed that web engine and pdf are now so-called “extension modules”. I understand the concept in principle (I think the idea of separating deployment of web engine from Qt as a whole, so you can patch issues separately, is about a decade old). Can someone

[Interest] Using QtConcurrent on Compiler Explorer

Can anyone give me a hint on how to bring a Qt code example using QtConcurrent to compiler explorer? I seem to lack a way to configure which Qt modules are available. I even tried to import a little cmake project that specifies the Qt modules, but they seem to be ignored. Kind regards Robert _

Re: [Interest] QMessageBox not displayed when monitor is switched off

Re: [Interest] QMessageBox not displayed when monitor is switched off

To clarify: You mentioned you were blind. Do you use some kind of screen reader to gather the content of the message box? How does the message box not appearing affect you? I believe for seeing people, it may appear as a reasonable optimization to not show a message box when the screen is off. So

[Interest] Status of TextDocument in TextEdit (6.8)

Hi! When doing anything complex with the content of a (QML) TextEdit, the TextDocument is just too good to ignore, but it is marked as preliminary. Now let’s say, in Qt 6.8, I restrict myself to the following: -) Pass the TextDocument property to C++ as QQuickTextDocument -) From QQuickTextDocum

[Interest] Why does QVector2d not have copy/assignment?

I was investigating why one of my simple structs was not copyable. Turns out that QVector2d has no copy constructor / copy assignment operator (Qt 6.7.2). This is interesting, since it is a) possible to construct a QVector2d from a QVector3d b) possible to construct a QVector3d from a QVector2d a

[Interest] Future of constexpr in Qt?

I’d like to use constexpr more in the future in order to catch UB in compile-time tests of functions. Qt has a little constexpr sprinkled here and there, but not a lot. Does anyone know if there are plans to expand Qt in this direction? Kind regards Robert This

[Interest] Is it safe to construct QBindable from QProperty* via QUntypedBindable?

I use QBindable a lot in C++ classes that expose properties to QML. My typical property implementation looks as follows: Q_PROPERTY(qreal x BINDABLE getBindableX READ default FINAL) //... QProperty m_X; //... CPropertyClass::getBindableX() const { return &m_X; } I got the idea to use "&m_X" t
