enum not in the scope of second class [SOLVED]

Projects Programming

Hi all,

I have a class (Flag) that uses an array[3] of objects of another class (Color). Color has an enum for 3 colors.

In Flags, I want to be able to set the colors.

Here is the .h code:

#ifndef BugEnum_h
#define BugEnum_h

class Color {
  public:
    Color();
    enum Colors {RED, WHITE, BLUE};
    Colors color = BLUE;
    Colors _color = RED;
    virtual void setColor(Colors newColor);
  private:
};

class Flag {
  public:
    Flag();
    Color flagColors[3];
  private:
    virtual void setFrance();
};

#endif

Here is the .cpp code:

#include "Arduino.h"
#include "BugEnum.h"

Color::Color();
void Color::setColor(Colors newColor) {_color = newColor; }

Flag::Flag();

void Flag::setFrance() {
  flagColors[0].color = BLUE;
  flagColors[1]._color = WHITE;
  flagColors[2].setColor(RED);
}

I get that RED, WHITE and BLUE are not declared in this scope.

How can I get them in scope of Flag?

Thanks for your help

Shouldn't Flags inherit from Colors?

Actually not.

I just want to use three Color objects, like I would use three Servo objects.

It seems that the problem arises because of the array.

I added 2 lines with a Color member of Flag and there is no warning from the compiler for them.
The .h code:

#ifndef BugEnum_h
#define BugEnum_h

class Color {
  public:
    Color();
    enum Colors {RED, WHITE, BLUE};
    Colors color = RED;
    Colors _color = RED;
    virtual void setColor(Colors newColor);
  private:
};

class Flag {
  public:
    Flag();
    Color flagColors[3];
    Color _rope;          //<<<<<<<ADDED
  private:
    virtual void setFrance();

};

#endif

The .cpp code:

#include "Arduino.h"
#include "BugEnum.h"

Color::Color();
void Color::setColor(Colors newColor) {_color = newColor; }

Flag::Flag();

void Flag::setFrance() {
  flagColors[0].color = BLUE;
  flagColors[1]._color = WHITE;
  flagColors[2].setColor(RED);
  _rope.color  = BLUE;             //<<<<ADDED
}

Now, that is strange.

No problem doing it in the sketch either (even with the array):

#include "BugEnum.h"
Color testColor[3];

void setup() {
  // put your setup code here, to run once:
testColor[0].color = WHITE;
}

void loop() {
  // put your main code here, to run repeatedly:

}

very, very strange.

Huh?

@BulldogLowell. Have you seen Post #4?

This is something we can easily do. Create an array of objects. The code I posted there works. I have used it numerous times.

But in a class, it does not seem to work. Maybe I am clumsy about it, but there should be a way that a class can use an array of an object of an other class.

No?

void Flag::setFrance() {
  flagColors[0].color = Color::BLUE;
  flagColors[1]._color = Color::WHITE;
  flagColors[2].setColor(Color::RED);
}

Why is the enum Color a class member? Make the stupid thing global!

Thank you very much for your help with this syntax, PaulMurrayCbr.

Really appreciate it.
