---:
---:
---:
---:I am finally sitting down and trying to teach myself vtk, and
---:am at the point of tinkering with the Examples to add functionality
---:(for instance, adding a thresholder and a couple more scales
---:to the Histogram example to allow interactive thresholding).
---:
---:I have noticed a *lot* of commands that I cannot find 
---:documentation --
---:such as BindTkImageViewer or BindTkRenderWidget or 
---:GetWidgetVariableValue.
---:
---:For instance, in the HistogramWidget.tcl example there is
---:the command:
---:
---:proc HistogramWidgetRender {widget} {
---:  ...
---:  ...
---:   set accumulate [GetWidgetVariableValue $widget Accumulate]
---:  ...
---:  ...
---:}
---:
---:
---:As far as I can figure, neither GetWidgetVariableValue nor
---:Accumulate are Tcl commands (but my command of Tcl is 
---:*also* sparse), 
---:they are not listed in the User's Guide index, and I cannot 
---:find any 
---:VTK documentation of them.  
---:
---:Perusing the automated documentation doesn't seem to help; as far as
---:I can tell they aren't part of a documented class (or at least
---:I can't tell what class they are a part of).
---:
---:I have found a few by scanning the User's Guide, but thumbing
---:through a book at random is an inefficient way of finding 
---:information.
---:
---:Is there an implied class here I am missing that 
---:GetWidgetVariableValue
---:is a method in?
---:
---:Is there a full list somewhere of these kinds of commands? 
---:
---:Thanks!
