QML and Qt Quick

@Bob64 said in Qt 6 TreeView and selection: A QML specific question is that if I did want to make a branch selected, then is it simply a case of adding a tap handler in the delegate somewhere and calling setCurrentIndex on the selection model, using the index of the current delegate? If you pass the Select flag to setCurrentIndex then yes. Note that TreeView (as inheriting from TableView) use an internal proxy model so you'd have to map the index of the delegate to get an index in the actual underlying model : https://doc.qt.io/qt-6/qml-qtquick-tableview.html#index-method

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...(

@StudentScripter said in Feedback needed: QML is this the right way to link other QML Files?: removing RESOURCE_PREFIX / is no problem, works still fine, thanks. :D Good to hear, that's what I expected :) There were some changes in Qt 6.5 to make things easier, so you should no longer need to specify RESOURCE_PREFIX unless you want some unconventional structure (which is not recommended) However do you mean changing all mymodules mentions to mymodulesplugin or only this one? I meant only one: target_link_libraries(appQmlLibraryTest PRIVATE Qt6::Quick mymodulesplugin # <-- Like this ) Cause when changing only one it gives me errors. Can you please share the full error message? Without it, it makes it hard to troubleshoot for you. @StudentScripter said in Feedback needed: QML is this the right way to link other QML Files?: Also another question what to do if i wanted to add another subfolder inside my mymodules/ directory? Lets say: mymodules/extras You could create a new QML module (in mymodules/extras/CMakeLists.txt)

@MattP2 I don't see how this works. Depending on your input/original color you will get a different gray value in the computation: color.rgb += brightness * color.a; float gray = dot(color.rgb, vec3(0.299, 0.587, 0.114)); Then this gray value will affect to colorizationColor in: color.rgb = mix(color.rgb, gray * colorizationColor.rgb, colorizationAlpha); So even if colorizationAlpha is 1.0, the gray affects the output. It would work, if color was clamped to (1,1,1) after applyiing the brightness, but that doesn't seem to happen. I always get my colorizationColor scaled in the result, even with brightness: 1.
