Problem compile "fake class". Work on Mac, not on Windows

mingw (windows)
#1

Hi!
Sorry for the strange title… but i don’t know how to define this technique.
I declared a class like this

because i need to use a pointer of this class inside another class… but i need to define this class later.
I don’t know if this is clear… so, this is my code:

#ifndef __IID_StudentPart__Button__
#define __IID_StudentPart__Button__

#include "ofMain.h"

class Button;

enum ButtonEvents
{
  BUTTON_EVENT_RELEASE,
  BUTTON_EVENT_MOUSE_OVER,
  BUTTON_EVENT_MOUSE_OUT
};

class EventFromDependentStationArgs : ofEventArgs
{
public:
  Button*               button;
  ButtonEvents          eventType;
};


enum ButtonState
{
  BUTTON_NORMAL_STATE,
  BUTTON_RELEASED_STATE,
  BUTTON_MOUSE_OVER_STATE,
  BUTTON_MOUSE_OUT_STATE
};

class Button
{
public:
              Button(string name);
              ~Button();
  ...
  ofEvent<EventFromDependentStationArgs> buttonsEvent;
  ...
};


#endif /* defined(__IID_StudentPart__Button__) */

So… i declared class Button because i need to use inside EventFromDependentStationArgs… and i have also to use EventFromDependentStationArgs inside my class Button.
This all works fine in Xcode… but in codeBlocks 12.11 on Windows8 i have some problem to compile.
Where i use

compiler says:
“Button” does not name a type

Any idea?

That’s weird. I removed OF dependency and compiled the following code on Ubuntu with g++ 4.6.3 which worked fine:

class Button;

enum ButtonEvents
{
  BUTTON_EVENT_RELEASE,
  BUTTON_EVENT_MOUSE_OVER,
  BUTTON_EVENT_MOUSE_OUT
};

class EventFromDependentStationArgs
{
public:
  Button*               button;
  ButtonEvents          eventType;
};

enum ButtonState
{
  BUTTON_NORMAL_STATE,
  BUTTON_RELEASED_STATE,
  BUTTON_MOUSE_OVER_STATE,
  BUTTON_MOUSE_OUT_STATE
};

class Button
{
public:
  Button() {};
  ~Button() {};
};

int main()
{
  Button b;
}

Does this code compile on your environment?

It may be a conflict with the names that somehow Codeblocks/MinGW isn’t liking.
Try and rename to MicuatButton, MicuatEventFromDependentStationArgs, MicuatButtonEvents.
