Dear user, the learning curve of ImGui in C++ can vary depending on the individual’s background and experience with C++ and graphic programming. Generally speaking, ImGui is designed to be easy to use and integrate into existing projects, which can make the learning curve relatively smooth for those with prior experience in C++ and graphics programming.
However, for beginners or those new to C++ and graphics programming, the learning curve may be steeper as they need to get familiar with the ImGui API, understand how to set up and configure it in their projects, and learn how to use it to create user interfaces.
Overall, ImGui is considered to be a user-friendly and well-documented library, so with some patience and practice, most developers should be able to pick it up relatively quickly. Additionally, there are plenty of online resources, tutorials, and examples available to help with learning ImGui.
