Unsolved Enum class sample

[Kutyus]

Hi!

I would like to use an enum class, this is in an included header:

class Ble: public QObject
{
	Q_OBJECT
		
public:
	enum Message
	{
		hubproperty			= 0x01,
		hubattachedio		= 0x04,
		hwnetworkcommand	= 0x08,
		portinputformat		= 0x41,
		portvalue			= 0x45
	};
	Q_ENUM(Message)
};

The compiler give this error:

undefined reference to `Ble::staticMetaObject'

Thanks in advance

@Kutyus

#include <QObject>

class Ble
{
	Q_GADGET
		
public:
	enum Message
	{
		Hubproperty			= 0x01,
		Hubattachedio		= 0x04,
		Hwnetworkcommand	= 0x08,
		Portinputformat		= 0x41,
		Portvalue			= 0x45
	};
	Q_ENUM(Message)
};

QObject included the top of header file

@Kutyus did you noticed the other changes in my post?

Ohh Q_GADGET :) I will try

@Kutyus actually more importantly

class Ble: public QObject

to

class Ble

[Kutyus]

Same error :(

@J-Hilk This error is produced by linker, in the object file, where is this line:

QMetaEnum::fromType<Ble::Message>().valueToKey(m)

m is a message code integer.

@Kutyus said in Enum class sample:

QMetaEnum::fromTypeBle::Message().valueToKey(m)

When I comment out the line wich contains the QMetaEnum::fromTypeBle::Message().valueToKey(m), the code is compiled succes.
How can i get the enum name from its value?
