First of all, when I start a new wxWidgets project it always begins with a few folders and some code already written. There's the "Sources" folder with "GUIFrame.cpp" "testApp.cpp" and "testMain.cpp" the "Headers" folder with "GUIFrame.h" "testApp.h" "testMain.h" and "wx_pch.h" the "Resources" folder with "resource.rc" and the "Others" folder with "WxWozFrame.fbp." What are these files? Which one(s) should I be writing in for my program? Or should I be creating a completely new file? I assume that it's either the "App" file or the "Main" file in the "Sources" folder that I should be writing in. Do I keep all the code already in there if I copy-paste test code into it? Or should I delete it? If I keep it, where should my test code go? For example, if I were to want to input this sample code into Code::Blocks in order to run it and test its result, how would I do so?
Also, when I first opened a wxWidgets project in Code::Blocks a popup appeared telling me something to the effect of "codeblocks does not know the global compiler variable." Later on when I closed Code::Blocks, reopened it, and opened a new wxWidgets project the message had disappeared and I haven't seen it since. Is this a problem I should be concerned about? Or did it fix itself? If it is something that needs to be fixed, how do I fix it?
Any help you can give me is appreciated. I'm very eager to start implementing this GUI stuff since there's a project I've undertaken that pretty much needs it. Any help is greatly appreciated!
