**Building a Virtual Tour of a Museum using Qt Quick and QML** In this article, we'll create a virtual tour of a museum using Qt Quick and QML. The application will have several stops, each with a detailed description and a 360-degree panoramic image. We'll use Qt's built-in 3D graphics capabilities to create a seamless experience. **Project Structure** Our project will consist of the following files: * `main.qml`: The main application file that handles user navigation and interaction. * `Stop.qml`: A reusable item that represents a single stop on the tour. * `StopController.qml`: A controller that handles the logic of updating the current stop and navigation. **Stop.qml** ```qml import QtQuick 6.0 import QtQuick.Controls 6.0 Item { id: stop property string name: "" property string description: "" property string image: "" ImageView { id: image source: image anchors.fill: parent } Text { id: nameText text: name anchors.top: image.bottom anchors.left: image.left anchors.margins: 10 } Text { id: descriptionText text: description anchors.top: nameText.bottom anchors.left: image.left anchors.margins: 10 } onPressed: { print("Stop pressed:", name) } } ``` This file defines a reusable item that represents a single stop on the tour. It has an image view that displays the panoramic image, a text item for the stop's name, and another text item for the stop's description. **StopController.qml** ```qml import QtQuick 6.0 import QtQuick.Controls 6.0 ListModel { id: stops ListElement { name: "Stop 1" description: "This is the first stop." image: "stop1.jpg" } ListElement { name: "Stop 2" description: "This is the second stop." image: "stop2.jpg" } } property int currentStop: 0 onPropertyValueChanged: { if (property === "currentStop") { updateStop(); } } function updateStop() { if (currentStop < stops.count) { stopPage.stop = stops.get(currentStop) } else { stopPage.stop = {} } } function nextStop() { if (currentStop < stops.count - 1) { currentStop++ updateStop() } } function previousStop() { if (currentStop > 0) { currentStop-- updateStop() } } ``` This file defines a controller that handles the logic of updating the current stop and navigation. It uses a ListModel to store the stops, and when the current stop property changes, it updates the stop page accordingly. **main.qml** ```qml import QtQuick 6.0 import QtQuick.Controls 6.0 import QtQuick.Window 6.0 ApplicationWindow { id: window visible: true width: 1080 height: 1920 StackView { id: stackView anchors.fill: parent initialItem: "Stop.qml" } StopController { id: controller currentStop: 0 } Keys.onPressed: { switch (event.key) { case Qt.Key_Left: controller.previousStop() break; case Qt.Key_Right: controller.nextStop() break; } } } ``` This file defines the main application window. It uses a StackView to manage the screens of the application, and it uses the StopController to handle the logic of updating the current stop and navigation. **Example Use Case** To run the application, create a new Qt Quick project and add the above code to the respective files. Make sure to replace the image sources with your own images. When you run the application, you should see a virtual tour of a museum with several stops, each with a detailed description and a 360-degree panoramic image. You can navigate between the stops using the left and right arrow keys. **Conclusion** In this article, we've created a virtual tour of a museum using Qt Quick and QML. We've used Qt's built-in 3D graphics capabilities to create a seamless experience, and we've relied on Qt's powerful scene graph to manage the user interface. We've demonstrated how to create reusable items and controllers to handle the logic of the application, and we've shown how to use Qt's built-in keyboard event handling to navigate between stops. **Commit Message** * Created a new Qt Quick project with a virtual tour of a museum * Added reusable Stop.qml and StopController.qml files * Implemented navigation logic in StopController.qml * Used Qt's built-in 3D graphics capabilities to create a seamless experience * Demonstrated keyboard event handling for navigation **API Documentation** * [Qt Quick 6.0 API](https://doc.qt.io/qt-6/quick-index.html) * [Qt Quick Controls 6.0 API](https://doc.qt.io/qt-6/quickcontrols6-index.html) **Leave a Comment** Have you used Qt Quick and QML to create a virtual tour of a museum or a similar application?
