Revision 1411 - (show annotations) (download)
Fri Oct 12 17:46:29 2007 UTC (16 years, 5 months ago) by schoenebeck
File size: 58259 byte(s)
* added status bar to the bottom of main window (independent area on the
  right shows whether gigedit is running stand-alone or attached to
  LinuxSampler)
* minor cosmetical fix in dimension manager widget
* regionchooser.cpp: temporary fix for a crash which occured when gigedit
  was compiled with CXXFLAGS="-g"
