    And as a bonus question, I fail to understand why modules are sometimes built as plain modules and sometime as libraries, by adding this (and then linking as a plugin): qt_add_library( StyleModule STATIC ) In that case, also, is this needed in the main.cpp: Q_IMPORT_QML_PLUGIN( StyleModulePlugin ); It works with and without, so I'm missing the point. There are a lot of examples circulating online, for various versions of Qt and all of this has changed quite a lot. The documentation being pretty thick, it's not easy to find up-to-date basic guidelines. Explanation or examples of use cases welcome! Thanks!

    @MaximBozek Bear in mind that I don't know anything about QML, only non-QML/widgets Qt. There I would expect to be able to go qDebug() << QFile::exists(":/fonts/Onest-....ttf") (I think that is right for non-QML, you could try on "qrc:/fonts/Onest-....ttf" but I believe the qrc is for QML only) and see it confirm that it can find that resource file at least. Can you do something similar from QML? I don't know that you can use any C++ code so I have to leave it to you). I don't know anything about whether fonts actually have to be installed or not. One would have thought not, they would work from the resource file, but I don't know.

How to embed foreign windows is indeeed described there.

    Hi @therealmatiss Since it is not in the MultiPointTouchArea docs it should not be a bug, maybe it just was not developed for it. You can ask about it in the qt dev mailing list and create a feature request in qt bug report https://bugreports.qt.io/secure/Dashboard.jspa. I am a bit work overloaded right now but when I find the time I will try to check qt code and see if this would be feasible to port.

    To anyone seeing this in the future who has the same problem as me with the jagged edges: The problem seems to actually be caused by the smoothstep that the Qt6 MultiEffect uses but the Qt5 OpacityMask doesn't. This is used for the maskThreshold- and maskSpreadAt- properties of MultiEffect. I don't really understand how these properties work, but by recreating this part of the shader in my own project I found out that if the first two elements of mask are about 0 and 1 respectively, the edges will be smooth. By looking into how these values are calculated, I found that setting maskThresholdMin to 0.5 and maskSpreadAtMin to 1.0 reaches basically this and the edges will then be smooth enough TLDR: Set these values in the MultiEffect: maskThresholdMin: 0.5 maskSpreadAtMin: 1.0 Edit: And just to clarify, layer.smooth: true also has to be set on the mask item

    Yes, I've tried resizing and centering w/ a parent <div>, parent <table><tr><td align="center"> and many other ways... and it seems to respect any other non-<img> element. There's no defaultStyleSheet on the document and no other HTML/CSS beyond the two <img> components. The images are added as resources like such (same QTextDocument as above): document->addResource(QTextDocument::ImageResource, QUrl("derp://img1.png"), img1); document->addResource(QTextDocument::ImageResource, QUrl("derp://img2.png"), img2); And then setHtml sets the following: <html> <body> <img width="50px" height="50px" src="derp://img1.png"/> <img width="50px" height="50px" src="derp://img2.png"/> </body> I've started putting together a new document w/ QTextCursor, but it'd be nice to just use HTML.

    @Scotsgeek Yes, you get that with Qt5.x, Ubuntu 22, Wayland. Nothing you can do about it. It's just a warning, that should not stop you porting 5 to 6. As it happens with Qt6.x, Ubuntu 24, Wayland that message does not appear (though I don't think that means requestActivate() does anything). Still plenty of Wayland issues outside Qt, for my part I have made Ubuntu desktop revert to Xorg.

    @Deep-Patle Sorry I misread your post. To implement speech-to-text in C++, you can leverage speech recognition APIs or libraries such as Google's Speech-to-Text API, Microsoft Azure Speech API, or open-source libraries like pocketsphinx or deepspeech

    I know it's been a few years, but this might still be helpful to someone :) For me, this approach works: delegate: MyDelegate { MouseArea { id: _mouseArea anchors.fill: parent } Binding { when: _mouseArea.pressed target: _listView property: "interactive" value: false } } With this setup, you should be able to scroll the list view using the scroll wheel. When you perform a press-and-drag gesture, it will disable the scrolling or flicking behavior. Once you release the mouse button, the binding will be restored, making the list view interactive again, so you can scroll with the mouse wheel once more. Even when you have multiple elements (i.e., instantiated delegates), dragging across them won't reset the interactive property until you release the mouse button.

    @Markkyboy The whole problem with OpacityMask was QtGraphicalEffects since it is not included in Qt6 but I in a forum I found import Qt5Compat.GraphicalEffects and it now works like following: Rectangle { id: mask anchors.left: parent.left anchors.leftMargin: 15 width: 50 height: 50 radius: 25 clip: true } Image { id: storeIcon anchors.fill: mask source: "qrc:/image.png" fillMode: Image.PreserveAspectCrop layer.enabled: true layer.effect: OpacityMask { maskSource: mask } }
