**Course Title:** QML Application Development **Section Title:** Final Project Preparation **Topic:** Planning and starting your final project. **Objective:** By the end of this lab, you will have a clear plan and a solid starting point for your final QML application project. **Overview** In this lab, we will guide you through the planning and starting process of your final QML application project. You will learn how to brainstorm ideas, define project requirements, create a project plan, and set up your project structure. **Step 1: Brainstorming Ideas** Before starting your project, take some time to brainstorm ideas. What type of application do you want to build? What features do you want to include? What problem do you want to solve? Consider the following: * What are your interests or hobbies? Can you think of an application related to them? * What problems do you face in your daily life? Can you think of an application that solves one of those problems? * What type of application have you always wanted to build but never had the chance? Write down as many ideas as you can think of. Don't worry too much about feasibility at this stage. **Step 2: Defining Project Requirements** Once you have a list of ideas, choose the one that excites you the most. Now, it's time to define the project requirements. Consider the following: * What features do you want to include in your application? * What are the minimum viable product (MVP) features? * What are the nice-to-have features? * What are the technical requirements for your application? (e.g., platforms, Qt version, etc.) Create a document with the following sections: * **Project Overview**: Briefly describe your application and its features. * **MVP Features**: List the minimum viable product features. * **Nice-to-Have Features**: List the nice-to-have features. * **Technical Requirements**: List the technical requirements. **Step 3: Creating a Project Plan** Now that you have defined your project requirements, it's time to create a project plan. Consider the following: * What are the tasks you need to complete to finish your project? * How much time do you have to complete each task? * What are the dependencies between tasks? Create a Gantt chart or a Kanban board to visualize your project plan. You can use online tools like [Trello](https://trello.com/), [Asana](https://asana.com/), or [Microsoft Project](https://www.microsoft.com/en-us/microsoft-365/project/project-management-software) to create your project plan. **Step 4: Setting up Your Project Structure** Now that you have a project plan, it's time to set up your project structure. Create a new Qt project using Qt Creator. Choose the Qt Quick Application template. Create the following folders: * **qml**: This will contain your QML files. * **cpp**: This will contain your C++ files (if needed). * **assets**: This will contain your application assets (e.g., images, fonts, etc.). Create a **main.qml** file in the **qml** folder. This will be the entry point for your application. **Conclusion** In this lab, you have brainstormed ideas, defined your project requirements, created a project plan, and set up your project structure. You are now ready to start coding your QML application. **What's Next?** * Start implementing your project tasks according to your project plan. * Review the Qt documentation and Qt Creator tutorials for help with implementing your project. * If you have any questions or need help, leave a comment below. **Additional Resources** * [Qt Creator Tutorials](https://doc.qt.io/qtcreator-4.9/tutorials.html) * [Qt 5 Documentation](https://doc.qt.io/qt-5/) * [QML Tutorials](https://qmlbook.org/) **Leave a Comment** If you have any questions or need help, leave a comment below.
