Sounds insanely complex when just got a QIcon from somewhere and you want to feed it into UI. Well, thanks for clarifying that no [easy] solution is currently available in the Qt itself. -- ivan (@ratijas) ___ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest

A QQuickIcon is just a struct containing a URL plus some options (width, height, etc.). Internally to render the icon, the QQuickIcon's URL is just forwarded to a QQuickIconImage which will attempt to retrieve the image from the URL. So there is no easy way to feed a QIcon to a QQuickIcon as you must use a URL at some point. The standard solution is to use a QQuickImageProvider. In C++ you would implement your own QQuickImageProvider which will contain the QIcons. In QML then you would use a url like "image://myprovider/icon_id". Then the QML engine will call your QQuickImageProvider to retrieve the icon image. An alternative solution might be to use data urls, but I have never tried it.

Re: [Interest] QIcon vs QQuickIcon
As QIcon isn’t a gadget, you will probably need to make model roles for name and source and assign those to the QQuickIcon’s properties instead.

I got a QIcon icon, aquired from a model by a delegate. How do i use it in controls with all these icon.name [string], icon.source [url] groupped properties or even with just an Image type? All sane attempts failed. I'm left with this a decade-old StackOverflow answer to use custom Image Provider. Sounds like too much work for something that should be just here, out of the box? icon: model.decoration // file:///usr/share/plasma/plasmoids/org.kde.desktopcontainment/contents/ ui/ConfigLocation.qml:115:21: Unable to assign QIcon to QQuickIcon // no conversion from QIcon to this gadget type icon.name: model.decoration.name icon.source: model.decoration.source // ConfigLocation.qml:116:21: Unable to assign [undefined] to QUrl // ConfigLocation.qml:115:21: Unable to assign [undefined] to QString // probably because QIcon doesn't have introspectible meta-properties? -- ivan (@ratijas) ___ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest
