got the information, that the code only changes the textcolor of a whole
column. it is some months ago, that i made it. it was thoughtless,
sorry.
a supplement, a simple code, how one can achieve colorization for every
cell(row) is in the first attachment. (change 'background' to
'foreground' to colorize text instead of the cell)
the second attachment is a more complex one, using
gtk.TreeViewColumn.set_cell_data_func, again a trancoding from one of
the examples in the treeview-tutorial.
