progressbar_create(parent, col)
progressbar_value(progressbar, value)
progressbar_updatebarcolor(progressbar, col)

`parent`	object of the class `tkwin` representing the parent widget
`progressbar`	object of the class `tkwin` representing the progressbar widget
`col`	character string specifying progress color
`value`	numeric scalar specifying progress with value in range [0..100]

Progressbar widgets are created with progressbar_create.

The function progressbar_value sets the percent completion value that allows the widget to reflect the amount of progress that has been made, filling from left to right; that value is displayed as well.

The function progressbar_updatebarcolor changes the color used by the widget to display progress.

The progressbar_create method returns a tkwin object representing the progressbar.

Other methods are invoked for their side-effect.
