Problem with form class

[mini.oxford]

I have a problem with calling facilities during the operation of the program. I would like to use the classes during the operation of the entire program and refer to them, and if he wants to declare the class are forms like declare them in main.cpp everything will work properly?

Hi,

Your question is not clear enough. Can you provide an example to help us understand what you would like to achieve ?
