QML and Qt Quick

Is there anything else I am supposed to do other than create the resources file that links the pictures?

Based on a quick read of the documentation, I don't think that this strategy will work.

https://doc.qt.io/qt-6/qquickpainteditem.html#paint

Note: The QML Scene Graph uses two separate threads, the main thread does things such as processing events or updating animations while a second thread does the actual issuing of graphics resource updates and the recording of draw calls. As a consequence, paint() is not called from the main GUI thread but from the GL enabled renderer thread. At the moment paint() is called, the GUI thread is blocked and this is therefore thread-safe.

Warning: Extreme caution must be used when creating QObjects, emitting signals, starting timers and similar inside this function as these will have affinity to the rendering thread.

Interesting

The complete picture looks like this

Checkable and checked are not components of Button QML.

A similar question here; https://forum.qt.io/topic/36479/solved-button-checkable-and-checked-not-working albeit a different answer/outcome from my response. Regardless, I still myself, cannot use checkable or checked with Button.

@SGaist Thank you so much!

It turns out wrapping the child Layout in an Item does the trick. Don't know why and whether this is the best solution

import QtQuick import QtQuick.Controls import QtQuick.Layouts Window { height: 300 width: 240 visible: true StackLayout { anchors.fill: parent Item { Layout.fillWidth: true Layout.fillHeight: true ColumnLayout { anchors.fill: parent Rectangle { color: "red" Layout.preferredWidth: 100 Layout.preferredHeight: 50 Layout.alignment: Qt.AlignHCenter // Center within ColumnLayout } // other items } } // other items } }

So I reduced my file to an empty file

You can't compile an empty file. Also, I guess your project consists of more than just an empty file.
Please provide more information, else nobody knows what you're doing and what the problem is.
Did you try to create a new widget project in QtCreator and build it for Android?

Fixed in 6.8.2

I wonder if that forum post is referring to text components that support html to some extent, rather than to QML itself?

Though that page doesn't show any QML examples as far as I can see.

I recall having to try a few things when I first wanted to do this a few years ago. I don't know if what I arrived at is the "correct" approach, but the format that I found to work in QML and have stuck to ever since involves using a triple forward slash like this:

source: "qrc:///images/my-image.png"

@Praveen-Illa said in Facing an issue with Listview in Repeater:

Hi Team,

I am trying to control the visibility of the listview control on every button click for respective data model.
But, I am getting below errors at "visible: buttonRepeater.model.expanded"
Unable to assign [undefined] to bool

Edited to emphasize the problem:

Repeater { id: buttonRepeater model: groupModel delegate: Column { ListView { visible: buttonRepeater.model.expanded } } }

buttonRepeater.model.expanded is attempting to access a property called expanded in buttonRepeater's model, not a role called expanded within a row of the model. Printing the values of buttonRepeater and buttonRepeater.model should make this clear.

Looks like it's QTBUG-133587. I also have .js files in QML_FILES.

@jeremy_k Thank you for your input. It seems I have to rethink the concept.

Hi,

Are you looking for something like the Vulkan under QML example ?
