The aquahig package implements some Mac OS X-specific configurations to selected Tk megawidgets to make them better fit in visually with Mac interface conventions, similar to iTunes and other Mac applications. Currently supported widgets are the BWidgets Tree, the BWidgets ListBox, and Tablelist.
The aquahig package is developed and maintaned by Kevin Walzer. For more information, see http://tk-components.sourceforge.net/aquahig/index.html .
