C code challenge...

What would be a clever way to "redirect" the qDebug to be written as "text" to ui->textEdit->append(text);?

#ifdef DEBUG
text = "DEBUG serviceDiscovered( ... ";
qDebug() << text;
ui->textEdit->append(text);
#endif

#if 1
qDebug() << "Discovered service on"
<< serviceInfo.device().name() << serviceInfo.device().address().toString();
qDebug() << "\tService name:" << serviceInfo.serviceName();
qDebug() << "\tDescription:"
<< serviceInfo.attribute(QBluetoothServiceInfo::ServiceDescription).toString();
qDebug() << "\tProvider:"
<< serviceInfo.attribute(QBluetoothServiceInfo::ServiceProvider).toString();
qDebug() << "\tL2CAP protocol service multiplexer:"
<< serviceInfo.protocolServiceMultiplexer();
qDebug() << "\tRFCOMM server channel:" << serviceInfo.serverChannel();
#endif

Create your own Debug class to do it, and change all the qDebug calls to call your class. Then inside your class you can pass the text to qDebug itself, and to your textbox.

That is C++, not C. I show you how it could be handled in a similar scenario:

#include #include using namespace std;

#define STD_DEBUG

#ifdef STD_DEBUG
#define DBG(txt) cerr << txt
#else
#define DBG(txt) \
do { \
ostringstream os; \
os << txt; \
string s = os.str(); \
cout << "The debug string: " << s; \
} while (0)
#endif

int main()
{
DBG("foobar = " << 42 << "\n");
}
