示例1: makeServerText
QString ServersComboBox::makeServerText(const Host &host)
{
QString name;
name = host.address();
if (host.isValid()) {
if (name.indexOf(':') >= 0) {
name = '[' + name + ']';
}
name += ':' + QString::number(host.port());
}
return name;
}示例2: send
bool UdpSocket::send(const Host& host, const char* data, int size)
{
const uint32_t addr = host.address();
const uint16_t port = htons(host.port());
