progressdock - Draws progress bar over Mac dock icon
package require progressdock
The progressdock package draws a nice progress bar over a Tk/Mac application's Dock icon. It is especially useful for showing download/uploads, and similar activities. The package is based on the UKDockProgressIndicator class by Uli Kusterer. See the included "demo.tcl" file with the source code distribution for an illustration of usage.
