[Beginner] Practical Qt/QML Programming for Stepping Up to Intermediate Level

Section 1. Introduction to the Course
In this section, we will take an overall look at what you will learn in this course. We will also introduce reference sites and documents.

Section 2. Implementing Web server & Secure Web server
There are many types of web servers, such as Apache and IIS, used to provide web services. And to provide the desired information to users who access the web server using a web browser, server-side scripts such as PHP, ASP.NET, and JSP must be used. This involves quite a bit of tedious work. However, in Qt, all these functions 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 slot connected to the corresponding signal is executed. In this way, you can easily implement the web services that a web server aims to provide using Qt.
In this section, you will learn how to implement a web server and how to provide services by distinguishing requests received from users. You will also learn how to implement HTTPS for a secure web server along with HTTP.

Section 3. Implementing a Client using RESTful API
It is called REST or RESTful API. It refers to an API that complies with the architecture called REST (Representational State Transfer) and means implementing it according to REST design principles. In this section, you will learn how to implement a RESTful Client using Qt according to REST API design principles.

Section 4. Implementing a Simple Chatting Server and Client
You will learn how to implement a TCP protocol-based Chatting Server that allows multiple users to connect and chat using the Network module provided by Qt. Additionally, you will learn how to implement a Chatting Client to chat with users connected to the Chatting Server.

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 finishes providing the service to the user (web browser). To solve the issues of wasted network resources and connection latency caused by repeated connecting and closing for every request, WebSocket was developed to maintain a persistent connection through the HTTP protocol.

In this section, you will learn how to implement a WebSocket-based chat server using Qt. Additionally, you will learn how to implement a chat client using HTML5 and JavaScript so that it can run in a web browser.

Section 6. Audio Player
In Qt, you can easily implement various multimedia applications. In this section, you will learn the concepts of audio Sample Rate and Bit Rate before implementing a real-world project. You will also learn how to calculate bytes during the process of decoding 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 to Transmit Microphone Audio via a Network
In this section, we will implement two applications using Qt. In the first application, you will learn how to implement an application that extracts audio data from a microphone and transmits it via the network UDP protocol. In the second, you will learn how to implement an application that outputs audio data received via the UDP protocol to a speaker.

Therefore, in this session, we will learn how to implement a mini network radio station by implementing an application that transmits and receives voice data.

Section 8. Implementing a Video Player
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 will learn how to handle camera devices connected to a computer using the Qt Network module. And you will learn how to implement an application that handles camera devices connected to a computer.

Section 10. PDF Viewer
Qt provides various PDF-related classes to handle PDFs easily. In this section, you will learn how to implement an application that displays PDF files on the screen.

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

Section 12. Data Communication Between Applications Using Google's Protocol Buffers
Protocol Buffers, developed by Google, serialize data and convert it into binary data format for storage. Conversely, they also convert serialized binary data back into structured data and store it in a structure format. Protocol Buffers can be utilized for IPC in various applications. In addition to C++, Protocol Buffers can be used in various programming languages. Qt makes it easier to use Google's Protocol Buffers.
In this section, you will learn how to exchange data between applications using Protocol Buffers.
Furthermore, you will learn how to implement applications that exchange data over a network and how to use Protocol Buffers during data exchange.

Q. Is there anything I need to prepare before taking the course?

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

Q. Can I download the examples used in the course?

Yes, it is possible. You can download the project source code used in the class from each session.

Q. Are there any reference materials or textbooks for the course content?

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

Q. Is it possible to participate in the class after installing Qt on Ubuntu or macOS platforms?

Yes, it is possible. You can participate in the class on Linux as well as macOS. Therefore, you can set up your development environment and join the class on whichever platform you prefer among MS-Windows, Linux, and macOS.
