[Level 1] Python Programming with Qt: Introduction

Section 1. Starting the lecture
Before the lecture begins, this section provides an overview of the entire learning process. This section introduces the instructor and summarizes the key content covered in each section, helping you grasp the overall flow of the lecture.

Section 2. Lecture Materials
This section provides all the example source code files used in the lectures, starting in Section 3 , in a compressed file for download. This section is provided for reference purposes only, not as part of the course.

Section 3. Setting up the development environment
This section delves into how to set up a development environment for Python programming using Qt. We'll also explore how to use Visual Studio Code as an IDE for writing source code.

Section 4. Getting Started with Qt Programming
Learn simple GUI programming in Python based on Qt. This will lay the foundation for effectively leveraging Qt in Python.

Section 5. Signals and Slots
Signals and slots are Qt's core event-handling mechanisms. A signal indicates the occurrence of a specific event, and a slot is a function responsible for processing that event. For example, you'll learn how a signal generated by a button click and its associated slot function work.

Section 6. Qt Resources
The Qt Resource System provides the ability to integrate various resources (images, icons, sounds, etc.) required by an application into an executable file. This system simplifies file path management and improves security and performance. In this section, you'll learn how to utilize this resource system.

Section 7. Qt Designer
Qt Designer is a tool for intuitively designing user interfaces for Qt applications. By arranging widgets and adjusting their properties via drag-and-drop, you maximize the efficiency of your UI design. In this section, you'll learn how to design GUIs using Qt Designer.

Section 8. GUI Programming Using Style Sheets
Qt Style Sheets are a powerful tool for fine-tuning the appearance of UI elements. Using CSS-like syntax, you can define the styles of buttons, text, and layouts. In this section, you'll learn how to utilize Qt Style Sheets.

Section 9. Implementing a Multilingual Application
Qt provides features that make it easy to develop multilingual applications. In this section, you'll learn how to develop applications that support multiple languages using Qt's multilingual tools.

Section 11. QMainWindow
QMainWindow is a class ideal for implementing structured GUIs in desktop environments. You'll learn how to effectively manage standardized GUI elements, such as menus, toolbars, main widgets, and status bars.

Section 10. Layout
Layouts provide the ability to efficiently arrange widgets in Qt and dynamically adjust them based on screen size. In this section, you'll learn about Qt's various Layout features.

Section 12. Model / View
Qt's Model/View architecture provides powerful capabilities for visually representing large amounts of data in a variety of formats. In this section, you'll learn how to utilize the Model and View provided by Qt.

Section 13. File I/O and Stream Handling
In this section, we will learn how to input and output files using QFile, and how to use QDataStream and QTextStream to efficiently process large amounts of data.

Section 14. 2D Graphics Using QPainter
The QPainter class is used to draw 2D graphic elements in QWidget. Learn in-depth techniques for displaying shapes, lines, text, and images.

Section 15. QPainter in Practice - Chroma Key Image Processing
Learn QPainter in depth by replacing the colors of a specific background image with another image using the chroma key technique. This will deepen your understanding of QPainter.

Section 16. Implementing a Timer
Learn how to call a specific function at set intervals using the QTimer class and see a practical example of event-based programming.

Section 17. Thread Programming
Learn how to easily perform thread programming by utilizing Qt's thread-related classes, and master how to implement threads that satisfy re-entrancy in a multi-threaded environment.

Section 18. Custom Widget
Learn how to create Custom Widgets to implement UI elements that cannot be expressed with existing widgets, and also acquire techniques for implementing non-standard windows.

Section 19. Database
Qt provides a unified API for accessing various databases. In this section, you'll learn how to use Qt's database API to work with various databases, including MySQL, MS-SQL, Oracle, and SQLite.

Section 20. XML
Learn how to easily process XML data using Qt's XML module. Master XML data handling techniques using SAX and DOM.

Section 21. JSON
Learn how to efficiently process JSON data using Qt's JSON module and deepen your understanding of the JSON format.

Section 22. Printer Support
Learn how to print text or images on a printer, and acquire skills in implementing output applications through integration with actual printers.

Section 23. Network
Learn how to easily develop TCP/IP-based network applications using the Qt Network module. We'll cover practical examples using the TCP and UDP protocols.

Section 24. Creating an installation distribution for distributing the developed SW.
In this section, we will learn in depth how to convert Python source code into an executable file and how to create installers for various platforms using the Qt Install Framework.
