QML Slider implementation guide model value in Qt 6.5 when using TwoWay Binding
I need some guidance on This might be a silly question, but I'm relatively new to this, so bear with me... I've been trying to implement a QML Slider that updates a model value dynamically, but I'm running into issues where the model doesn't seem to reflect the changes made by the slider... My initial setup involves a `ListModel` that holds integer values which I want to manipulate with a `Slider`. Here's a simplified version of my code: ```qml import QtQuick 2.15 import QtQuick.Controls 2.15 ApplicationWindow { visible: true width: 400 height: 300 ListModel { id: myModel ListElement { value: 10 } ListElement { value: 20 } ListElement { value: 30 } } ListView { model: myModel delegate: Item { width: parent.width height: 100 Text { text: "Value: " + model.value } Slider { id: valueSlider from: 0 to: 100 value: model.value onValueChanged: { model.value = valueSlider.value // This line doesn't seem to update the model } } } } } ``` When I move the slider, I expect the corresponding model value to update, but it doesn't change even though I've set the `value` of the slider to `model.value`. I noticed that the `onValueChanged` signal handler is called, but `model.value` remains unchanged. I checked the documentation and it looks like I should be able to achieve two-way binding this way. I've tried replacing `model.value` with `myModel.setProperty(index, "value", valueSlider.value)` but it throws an behavior stating "want to set property 'value' on a ListElement". Is there a specific way to handle updates to a model in QML that I'm missing? Is there a better approach to ensure that the model reflects the slider’s value? Any insights would be greatly appreciated! I'm developing on CentOS with Qml. Any suggestions would be helpful. Am I missing something obvious? This is my first time working with Qml LTS. Any pointers in the right direction? My team is using Qml for this desktop app. Thanks for any help you can provide!
