Hello, I'm here again with another issue. :)
I have written almost every part of my program what I'm gonna need (I did it as separate projects).
But now I need to create "main program". And I don't know exactly what is the best way to add these "parts" of program to main window when I click to menu in menu bar.
So far I have two parts- first one with drawing, and second one with a table which shows the records from database.
