QML and Qt Quick

Using a single c++ model with a Repeater + DelegateChooser would be the idomatic and simpler way.

@JKSH Thx. Will try it today.

@Tom-asso hi, Check the build log, you likely have a warning about that issue from the compiler.

I would be interested in this too. I happened across ColourImage in some Qt source the other day and thought it looked useful before realising that it's internal. This was in 6.8. I am porting some Qt5 code at the moment and was trying to figure out how to colour an svg. I used to use GraphicalEffects and the compatibility library isn't available with the in-house Qt build I have to use. Meanwhile MultiEffect, which I understood to be the Qt 6 replacement, doesn't appear to work, with no clues provided as to why not.

@GrecKo Thanks for the tip. In the Qt 5 tree view, the index was provided directly to the delegate but I see that it has to be derived from the row and column that are provided to the delegate in Qt 6. So I need to make sure I use the provided index() method on the tree to do this, rather than going directly to the model.

My professional guess is that Connections is specifically designed to reference a QtObject or null, ensuring type safety and clarity in signal connections. Source is a more generic term in QML, commonly used for properties like Image.source or Component.source, which refer to the data or component being displayed or instantiated.

Confusing indeed: https://bugreports.qt.io/browse/QTBUG-130864

This did it - thank you so much, I've been trying to figure this out forever.

Hi and welcome to devnet, While I understand the lock you are into, testing with a more recent version can help you check whether what you actually have is working. Two possible outcomes: it does and you can try to back port the changes needed it does not and you have to check if it's an issue (and possibly fill a new ticket about it)

So what did you had to do with your code to make it work ?

I found the solution, shortly after having posted : I was missing acceptedButtons: Qt.AllButtons

Thank you Vitalii777 and SuhasKrishanamurthy for your help. Much appreciated! The code above working good.

@JKSH Thanks for the answers!

@Dika The solution is to: Register your class using QML_SINGLETON Do not call qmlRegisterSingletonType<>() If you don't have (or don't want) a default constructor, implement a static member function called create() to act as a factory. See https://doc.qt.io/qt-6/qqmlintegration-h-qtqml-proxy.html#QML_SINGLETON for an example

It looks like it won't be possible to rebuild the old project without migrating the code to Qt 6...(
