[GRASS-dev] reading items from element list

[Michael Barton]

Testing our r.prominence, I found that it will not locate any raster  
files for input in the GUI. Looking at the code, it calls fcell.  
According to element_list, this is a valid element, but it is not  
clear how it is called, since it is called a "support_element". The  
program requires a floating point raster, so specifying it in the GUI  
is a good idea.

cell:rast:raster:raster files
   cellhd:header
   cats:category
   colr:color
   hist:history
   cell_misc:misc
   fcell:fcell
   g3dcell:g3dcell


So, does the GUI parser recognize support_element items? If so, how  
are they to be called in the the section that specifies the GUI for a  
module?
