[Qt-interest] adding zero to QByteArray

[Parker]

Hello all, 
I have another small newbie question here. 

I'm trying to add a integer zero value to QByteArray . 

QByteArray datagram;
 datagram.push_front(0x0);
datagram.push_front(0x1);



But the first call generates an error. It seems it thinks 0 could be a null pointer ot something ? Any ideas how to put 0 in it ? 

I have to send some bytes trought the wire with UDP here.
