C++ Programming By Example - Finishing the Text Editor

The video tutorial covers the development of a text editor application using Visual Studio. It begins by removing unnecessary message prints and proceeds to implement file opening functionality using QFileDialog. The tutorial demonstrates how to use the getOpenFileName function to allow users to select text files. After testing the file opening feature, the tutorial adds file saving functionality using getSaveFileName. The video concludes with final touches to the text editor, making it similar to Notepad, and previews the next section on building a painting application in Qt 5.
