-Here we have the situation where along with user data to be displayed in the view there also are stored system parameters, namely, the foreground and background colours for the two view columns. As previously announced, in this example program entire row is manipulated with their respective ((*set_cell_data_funcs'*)) blocks. That is, all columns for all the cell renderers in this tree view (which contains only two columns/renderers) trigger execution of their pertinent ((*set_cell_data_func*)) methods and code blocks. What is also interesting is how in some of these blocks multiple data in the same row from different columns are consulted. If you understand this program, you should also understand that model columns do not map to view columns.
