Introduction

This section describes examples illustrating the use of a GUI library. We will try to show you how windowed applications are created step by step.
The entire source code is available in the Tutoirial\GUI subdirectory of the Gentee installation folder. It is recommended to study the examples in the order they are given because many moments will be skipped if they are described in previous programs. Along with the source code, you can find the runme.g file in this directory. It is used to create and run the program of a certain version Day1, Day2, etc.. You will have to specify the number of the day to run it. Once compiled, the created exe file will be automatically launched. Thus, you can run different versions one by one and follow changes made in them step by step. The runme.g program is configured to create exe files that do not require gentee.dll. If you want to reduce the size of applications and use gentee.dll, specify the -d parameter when you run ge2exe.
Besides, you may need a resource editor and a resource compiler. As a rule, they come together with almost all common programming languages. As alternative free software, we can recommend:
Resource editor ResEd
Resource compiler GoRC

Calculator
