All, This message is a heads-up to alert developers/packagers that the Qt3/TQt3 ABI is not backwards compatible with 3.3.x as of GIT hash 0eb9f5e. This decision was not made lightly. The QWidget class did not contain enough data members to add modern NetWM/Motif configuration flags due to poor design, and as you may be aware adding data members is one of the only ways to break ABI compatibility. I have also added new unused reserved data members to ensure that this problem does not happen again in the near future. With this ABI bump comes a new version number, 3.4.0. If you need to maintain backwards compatibility for any reason, I strongly suggest locally reverting the 0eb9f5e patch in a copy of the latest qt3 sources from GIT. The ABI is not set in stone and may undergo further changes before R14.0.0 is released, however I will send a similar message to the lists if this occurs. Packagers, you will need to initiate a full rebuild of qt3 or tqt3, then rebuild all TDE packages from scratch once the new qt3/tqt3 version is installed. Timothy Pearson Trinity Desktop Project
