Author:

Message:

3rdparty: os2/xsystray: Implemented adding an icon to the system tray (one icon so far) and automatically removing it if the associated window gets destroyed w/o doing so (for example, as a result of unexpected application termination).

Location:

trunk/src/3rdparty/os2/xsystray

Files:

• xsystray.c (modified) (14 diffs)
• xsystray_api.c (modified) (7 diffs)
