ede/efiler/EDE_FileDetailsView.cpp
Vedran Ljubovic b7a0958278 EFiler v0.2.2:
- Use edelib::Window (fixes problem with titlebar icon and some cruft in main)
- Store user preferences in edelib::Resource
- Work better with edeneu icon theme, follow fdo icon-naming-spec
- Expand . in directory path (e.g. when called from command line), show just last part of path in window title, full width status bar :)
- Some fixes to ExpandableGroup usage, use EG by default
- In fileops, don't update view manually when notify is available
- Improve documentation of EDE_FileView.h
- Temporary "Open with" callback for testing
