[Beginner] Practical Programming in Qt/QML to Advance to Intermediate Level

Section 1. Starting the lecture
This section provides an overview of the material covered in this course. It also provides reference sites and documentation.

Section 2. Web server & Secure Web server implementation
To provide web services using a web server, there are many types of web servers, such as Apache and IIS. And to provide users with the desired information by accessing the web server via a web browser, server-side scripts like PHP, ASP.NET, and JSP are required. This can be quite a cumbersome process. However, in Qt, all of this functionality can be easily implemented using the web server module provided by Qt.
In other words, when a specific request is received from a user, the corresponding Signal and associated Slot are executed. In this way, using Qt, you can easily implement the web service that the web server wants to provide.
In this section, you'll learn how to implement a web server and how to distinguish and serve user requests. You'll also learn how to implement HTTPS for a secure web server, in addition to HTTP.

Section 3. Implementing a Client Using RESTful API
This is called a REST or RESTful API. It's an API that adheres to the REST (Representational State Transfer) architecture and is implemented according to REST design principles. In this section, you'll learn how to implement a RESTful client using Qt, following REST API design principles.

Section 4. Implementing a Simple Chatting Server and Client
This course will teach you how to implement a Chatting Server, a multi-user chat service based on the TCP Protocol, using the Network module provided by Qt. You'll also learn how to implement a Chatting Client, which allows users connected to the Chatting Server to chat with each other.

Section 5. Implementing a WebSocket-based Server and a Client Using HTML5
The HTTP protocol closes the connection once the web server receives a request and completes providing the service to the user (web browser). To address the network resource waste and connection delays caused by repeatedly connecting and closing the connection for each request, WebSockets were developed to maintain the connection through the HTTP protocol.

In this section, you'll learn how to implement a WebSocket-based chatting server using Qt. You'll also learn how to implement a chatting client using HTML5 and JavaScript so it can run in a web browser.

Section 6. Audio Player
Qt makes it easy to implement a variety of multimedia applications. In this section, you'll learn about audio sample rates and bit rates before implementing a real-world project. You'll also learn how to calculate bytes during the decoding process of encoded (compressed) data, such as MP3.
And you will learn how to implement an application that plays audio files encoded with the MP3 codec using the Multimedia module provided by Qt.

Section 7. Building a Mini Broadcasting Station that Transmits Microphone Voice Over the Network
In this section, you'll implement two applications using Qt. The first application extracts audio data from a microphone and transmits it via the UDP network protocol. The second application outputs the received audio data via the UDP protocol to a speaker.

So, in this lesson, we'll learn how to implement a mini network radio station by implementing an application that transmits and receives voice data.

Section 8. Video Player Implementation
In this section, you will learn how to implement an application that plays video files using the Multimedia module provided by Qt.

Section 9. Implementing a Video Output Application Using a Camera
In this section, you'll learn how to handle camera devices connected to your computer using the Qt Network module. You'll also learn how to implement an application that handles camera devices connected to your computer.

Section 10. PDF Viewer
Qt provides various PDF-related classes to facilitate PDF handling. In this section, you'll learn how to implement an application that displays PDF files onscreen.

Section 11. Printer Support
Learn how to print text or images to a printer connected to your computer. Therefore, in this section, you'll learn how to implement an application that prints text to a printer.

Section 12. Inter-Application Data Communication Using Google's Protocol Buffers
Protocol Buffer, developed by Google, serializes data, converts it into binary data, and stores it there. Conversely, it converts serialized binary data back into structured data and stores it again in structure form. Protocol Buffer can be used as IPC in a variety of applications. Protocol Buffer is available in various programming languages, not just C++. Qt makes it even easier to use Google's Protocol Buffer.
In this section, you will learn how to exchange data between applications using Protocol Buffers.
And you will learn how to implement an application that exchanges data over a network and how to use Protocol Buffers for data exchange.

Q. Is there anything I need to prepare before attending the lecture?

The Qt version to be used in the lecture is explained in Section 1. Therefore, please refer to Section 1 and then install Qt.

Q. Can I download the examples used in class?

Yes, you can. You can download the project source code used in class for each session.

Q. Are there any reference materials or textbooks for the lectures I am studying?

I'm an administrator for the Qt Developer Community ( qt-dev.com ). You can find additional resources related to Qt and QML on this site.

Q. Can I participate in classes after installing Qt on Ubuntu or macOS platforms?

Yes, you can. You can participate in the class not only on macOS but also on Linux. Therefore, you can set up a development environment on your preferred platform—MS-Windows, Linux, or macOS—and participate in the class.
