Project "rDebug"

  • Loving qDebug? But missing some things?
  • Just want to see your debugs/logs in a QtWidget, like QListView?
  • But got crashes with qInstallMsgHandler (4.x) / qInstallMessageHandler (5.x)?
  • Missing file name, line numbers with qDebug 4.x?

You are welcome, here we go!
This is mostly a simplified re-implementation, which under the hood also uses parts of qDebug().
You can use

qDebug( "printf mask %s","is worse");

or

qDebug() << "streams" << "are more safe";

or a mix of both. You can select between all 7 BSD-Syslog levels (plus "Silent" and "All").
A two-liner can send Qt SIGNAL with the data, time stamp, location and level to your QListWidget (or whatever). Another two-liner can write to file and use different log level filtering.

For the start, some features of Qt5, like 

qDebug( &stream_device ) << "are not supported"; // and may never come.

stream_device is not supported.

Have fun, take part, help improving ...
THX!
