Hello, I’ve been working on this project for weeks. I have just about 20 tabs open, trying to learn about windows, and buttons etc. I have a lot of questions. Primarily, what does this error mean? (refer to the image) How do i fix it? The goal here is, very simply, to have a button appear on a window: 600×450 resolution. I’ve tried so many things, and am just very stumped, I want to learn. Please help. How do I create a button, what does this error message mean? I’ve yet to come across a YouTube Video or help page that has identified all the components of a window. Everything is scrambled. I will immensely appreciate a helpful response.
