Title: Is it possible to copy a window ?
Post by: hanhau on December 21, 2014, 04:06:39 pm

Hey Guys there, I am pretty new here at SFML :) Here´s my question:

Can I copy a RenderWindow ?
Like .....

sf::RenderWindow app1(sf::VideoMode(100,100),"app1",sf::Style::Default);
sf::RenderWindow app2 = app1;
 

I could need it in some ways, but I am actually search for other solutions for the problem.
That was it.

Thanks for answers :)
Have a nice day, Hannes ^^

sf::RenderWindow is derived from sf::NonCopyable so no, you can't copy it.

I can't imagine any case where one would need to copy a window.

Actually, I wrote a headerfile, wich contains a class with a function, that should draw in the mainwindow, wich gets initialized in the main.cpp. How can I do that ? Okay, copying Is not the right word, I just want to handle that in a other .hpp file, because of the handling with easier coding with more view about it.

I think you're asking how to pass a function argument by reference instead of by value.  This is basic C++ stuff; you should go read a good book about the language first (https://stackoverflow.com/questions/388242/the-definitive-c-book-guide-and-list).

Just call by reference or by pointer:

void foo(sf::Window& window)
{
    //do whatever you want with window like:
    window.draw(whatever);
}

Edit:
Do what Ixrec said ;)

The emphasis should really be on Ixrec's post, for your own sake.
