Using QMetaEnum

[lxman]

Right now I have a header file called enums.h as such:

enums.h

#ifndef ENUMS_H
#define ENUMS_H
 
#include <Qt>
 
enum paper_orient{portrait, landscape};
enum ruler_orient{top_ruler, bottom_ruler, left_ruler, right_ruler};
enum relationships_type{line_item, other};
enum settings_type{line_object, plot, text};
 
#endif // ENUMS_H

#ifndef ENUMS_H
#define ENUMS_H

#include <Qt>

enum paper_orient{portrait, landscape};
enum ruler_orient{top_ruler, bottom_ruler, left_ruler, right_ruler};
enum relationships_type{line_item, other};
enum settings_type{line_object, plot, text};

#endif // ENUMS_H

To copy to clipboard, switch view to plain text mode 

With this setup, wherever I want to use these enums, I just #include "enums.h" and they are available.

In learning to do things the Qt way, it appears that QMetaEnum would be a more streamlined approach.

In the docs, I find this example:

class MyClass : public QObject
 {
     Q_OBJECT
     Q_ENUMS(Priority)
 
 public:
     MyClass(QObject *parent = 0);
     ~MyClass();
 
     enum Priority { High, Low, VeryHigh, VeryLow };
     void setPriority(Priority priority);
     Priority priority() const;
 };

class MyClass : public QObject
 {
     Q_OBJECT
     Q_ENUMS(Priority)

 public:
     MyClass(QObject *parent = 0);
     ~MyClass();

     enum Priority { High, Low, VeryHigh, VeryLow };
     void setPriority(Priority priority);
     Priority priority() const;
 };

To copy to clipboard, switch view to plain text mode 

If I use this approach, does this mean that the Priority enum is only available within MyClass? What if I wish to use this enum in other classes? Ultimately that is what I would like to establish, is a series of global enums that are available anywhere in my project.
