Re: c++ and gtk

[Dan Rosen <dr cs brown edu>]

yeah, without any problems!

the only tricky bit is in the callbacks -- they're all done with function
pointers (which, to my knowledge, is the only way to do them in c) but the
functions all have to be static if they are to be class members.

my code ends up looking like this:

  class MyGtkButton {
  private:
    GtkButton* button_;
  public:
    MyGtkButton(char* title) {
      // initialize button, connect clicked signal, etc...
    }
  private:
    static void clickedSignal(..., gpointer data) {
      // cast data to MyGtkButton (pass the function "this",
      // to have access to members despite being static).
    }
  }

etc.

i guess i forgot some semicolons, but you get the idea :)
