My project file qt.pro is located in the same folder as a .ui file called texo.ui. From what I have read, it seems like a file ui_texo.h should be automatically generated when I try to build the project but I'm not positive. I am a Qt beginner and am quite lost. I had a similar problem initially with a file qgraphicsview.h, which I fixed by using finder to locate the file and then pasting it into the same file that qt.pro is in. Unfortunately, I can't locate a ui_texo.h file anywhere on my computer. Thanks in advance for any help, and let me know if you have any questions or if I haven't been clear!My project file qt.pro is located in the same f
