I have been trying to write a simple class file and can't figure out what I am doing wrong. It is one .h file, one .cpp file, and the main file. Any help would be greatly appreciated. It appears to not like my main file when compiling. I am getting errors on 11,13,16,17,19. In addition, I am getting errors on my QPushButton callout for "quit" and my QVBoxLayout in the main.cc

channelselected.h file
