    Arrays and Constructors

    Hi everyone. I have this class...

    Code:
    class ApplicationType
    {
    private:
       vUIButton Buttons[5];
    
    public:
       ApplicationType();
    ...
    };
    and I need the constructor of this ApplicationType to set up all my buttons. The buttons' constructors look like this:

    Code:
    vUIButton( char* Text, RectangleType* Area )
    (So normally I would make a button by saying "vUIButton ExitButton( "Exit", NULL );".)

    How do I do this with an array? I want the buttons to be like this:
    1. "New", NULL
    2. "Load", NULL
    3. "Options", NULL
    4. "Credits", NULL
    5. "Exit", NULL

    I know that i could do it like this...

    Code:
    vUIButton Buttons =
    {
       vUIButton( "New", NULL ),
       vUIButton( "Load", NULL ),
       vUIButton( "Options", NULL ),
       vUIButton( "Credits", NULL ),
       vUIButton( "Exit", NULL )
    };
    ...but this won't work in the constructor.

    How do I use an array's objects' constructors in the constructor of the class that contains them? (Wow, that was a weird sentence...)

    Thank you very much for your time. It is greatly appreciated!

    You don't. You can just skip the use of the array's objects' constructor and use member functions or whatever to set the data instead. Or you can use a vector and push_back objects which will allow you to use the constructor.
