I was just playing around with the qjackctl code to see if I can make the connection editor more powerful (undo, redo, selecting multiple connections etc).
Unfortunately I am stuck right at the start because I can't seem to get anything to stdout or stderr to help me understand what is going on in the code.
I did configure with --enable-debug and I can see that you used qWarning() in qjackctl.cpp which seems to get printed but if I use qWarning in qjackctlConnect.cpp for instance nothing gets out. Also, just including stdio and streaming to stdout or stderr doesn't work.
Apologies if this is a really stupid question as this is the first time looking closer at any Qt based code. I know I should probably be using gdb or something and go beyond using stdout but thats a whole 'nother thing to learn.
