QML Component implementation guide after model changes in Qt 6.5 - need guide with dynamic data binding
Hey everyone, I'm running into an issue that's driving me crazy. Hey everyone, I'm running into an issue that's driving me crazy. I'm experiencing an scenario where a QML component does not visually update when the underlying model data changes. I am using Qt 6.5, and my setup involves a ListView that is bound to a ListModel. When I add new items to the model, the ListView does not refresh to display the new items, and the current items sometimes appear stale or unresponsive. Here's a simplified version of my QML code: ```qml import QtQuick 2.15 import QtQuick.Controls 2.15 ApplicationWindow { visible: true width: 640 height: 480 ListModel { id: myModel ListElement { name: "Item 1" } ListElement { name: "Item 2" } } ListView { width: parent.width height: parent.height model: myModel delegate: Item { width: parent.width height: 40 Text { text: model.name } } } Button { text: "Add Item" onClicked: { myModel.append({ name: "Item " + (myModel.count + 1) }); } } } ``` I've attempted a few things to solve the scenario: - Ensured the model is being modified properly using the `append` method. - Confirmed that there aren't any visibility issues with the ListView. - Added `onCountChanged` signals to debug the changes in the model count, but they seem to be firing as expected. Despite all this, the ListView doesn't reflect the changes made to the model. I also tried using `ListView`'s `model.setProperty()` method to update existing items, but that yielded no visible result as well. Is there a specific property or method that I need to be aware of to ensure updates propagate correctly to the ListView? Any suggestions would be greatly appreciated! For context: I'm using Qml on Windows. Is there a better approach? I've been using Qml for about a year now. What's the best practice here?
