qRegisterMetaType and own class

[^NyAw^]

Hi,

I have my own class and I need to send objects of this class by SIGNALs SLOTs mechanism.
Now I'm using it without registering my class with "qRegisterMetaType (file:///C:/Qt/4.3.0/doc/html/qmetatype.html#qRegisterMetaType)" and passing the parameters as value(not references), but I don't have developed the copy constructor. It seems to work, could this produce any problems?

Thanks,

It shouldn't unless you try to send signals across threads. Then Qt will (or at least should) not let you do this.

Hi,

And doing this with timers? I use a timer that makes "polling". When "timeout" is triggered it call the slot that make some job and this slot emits a signal that contain an object of my class.

Thanks,

As long as signal arguments don't need to be serialized, there is nothing to worry about. Of course registering the meta type wouldn't hurt :)
