.. now with the edit field for the squelch level working properly again.
I had messed it up by setting the style to "numeric input" but realized 
too late that "numeric input" means 'digits only', so the box rejected 
the minus sign. So only non-negative SNR as squelch level. I had set the 
squelch level (which is saved between sessions in an ini file) before 
that modification.  Oops...
Also the waterfall zooming (via mousewheel) and panning (grab it with 
left mouse button) is working now.
Contrast- and brighness controls need some more work; they will possibly 
be replaced by min- and max displayed magnitude range (measured in dBfs, 
with AGC turned off this allows to check the absolute input levels. AGC 
masks poorly adjusted audio levels... not good)
Rik and Eberhard  : Thanks for the suggestions. The automatic carriage 
return isn't implemented yet, but that will follow very soon.
