I have been exploring doing some GUI programming with the wxWidgets toolkit as i am used to that from programming wxPython in python. I am doing the tutorials from zetcode and i am very mystified. (i think i spelt that wrong). This is the url http://zetcode.com/tutorials/wxwidgetstutorial/menustoolbars/ Its the first one on the page.
The issue i am having difficulty grasping is to do with the way that menu.h and menu.cpp work together because nothing ever seems to ever deal with menu.cpp yet it still defines the constructor and other functions. My questions is, how does it know to go to that file for the constructor? Or is that just all done when compiling, im just really confused as to why nothing is getting done to menu.cpp, its all menu.h that is getting included.
