[SOLVED] QVariant and user structures

[pdoria]

Hi,

I have this structure:

typedef struct
{
uint32 status_change_id;
boolean result_code;
uint8 reserved[3]; /* Set to 0 */
} driver_id_receipt_data_type;

typedef struct
{
uint32 status_change_id;
boolean result_code;
uint8 reserved[3]; /* Set to 0 */
} driver_id_receipt_data_type;

To copy to clipboard, switch view to plain text mode 

I'm trying to:

driver_id_receipt_data_type receipt;
QVariant packet;
// after filling the structure's members with data...
packet.setValue(receipt); // ERROR Line

driver_id_receipt_data_type receipt;
QVariant packet;
// after filling the structure's members with data...
packet.setValue(receipt); // ERROR Line

To copy to clipboard, switch view to plain text mode 

Could somebody please tell me what's wrong with this code?

I have this function:

void send_FleetManagementPacket(QDataStream & dstream, QVariant packet);

void send_FleetManagementPacket(QDataStream & dstream, QVariant packet);

To copy to clipboard, switch view to plain text mode 

which serves to send to arbitrary data to a stream.

I was hoping to pass the data through a QVariant thus eliminating the need for a ton of orverloaded functions...

TIA,
Pedro

Looking at the docs I've found the

Q_DECLARE_METATYPE(type);

Q_DECLARE_METATYPE(type);

To copy to clipboard, switch view to plain text mode 

So obviously I've tried it immediately ...

typedef struct
{
	quint32 status_change_id;	/* timestamp of status change */
	bool result_code;
	quint8 reserved[3];		/* Set to 0 */
} driver_status_receipt_data_type;
Q_DECLARE_METATYPE(driver_id_receipt_data_type);

typedef struct
{
	quint32 status_change_id;	/* timestamp of status change */
	bool result_code;
	quint8 reserved[3];		/* Set to 0 */
} driver_status_receipt_data_type;
Q_DECLARE_METATYPE(driver_id_receipt_data_type);

To copy to clipboard, switch view to plain text mode 

No joy...

This is what the compiler throws:
error: expected constructor, destructor, or type conversion before ';' token

TIA for any pointers!
Pedro.

The error message probably occurs because the compiler doesn't know the macro Q_DECLARE_METATYPE. Don't forget to include <QMetaType>.

By the way, use the correct class name in the macro:

Q_DECLARE_METATYPE(driver_status_receipt_data_type);
//  Q_DECLARE_METATYPE(driver_id_receipt_data_type);

Q_DECLARE_METATYPE(driver_status_receipt_data_type);
//  Q_DECLARE_METATYPE(driver_id_receipt_data_type);

To copy to clipboard, switch view to plain text mode

Txs Shentian!

the #include <QMetaType> was missing!
It's always the little things like this that bites you in a** !
