TkTray is an extension for managing system tray icons with Tk 
on X Window System.

   * Description: http://sw4me.com/wiki/Tktray

There are some other extensions for this purpose, like '''freedock''' mentioned at [system tray]. I decided to write my own implementation for a number of reasons:

   * '''freedock''' is good enough, but GPL license restricts its uses. 
   * '''tksystray''' introduces dependency on Imlib. Also, it manages icon windows in the way that prevents [wm geometry] and [winfo] from returning something useful. Copying conditions of '''tksystray''' are unclear, as no license file is provided.

Tktray is released under BSDL. It uses Tk image manipulation routines to handle images, thus no external dependencies are introduced.

Tktray will handle the case when the system tray manager is not running yet when an icon is created. When the tray manager starts later, Tktray will notice it and request docking for all existing icons.
