File type associations and opening when files are dragged.

[3DModelerMan]

How do you associate file types with your application? I need to do it for windows, and linux, and mac. And also, how do you make the files open when they are dragged to the program's icon?
Thanks.

Filename is in the main function argument parameter.
For the association stuff, I guess it happen in the register.

Not sure how with *nix systems, but with Windows it's stored in the registry.

When you drag a file onto a program or its icon, the file name and path of the dragged file are sent to the program as a command line argument.

Code: Select all

int main( int argc, const char* argv[] )

So like slavik said, it's passed as a command line argument. argc will give the the number of arguments, and argv will be an array of strings with the actual arguments (in your case, must likely a path to the file)
