gtkTreeModelFilterSetVisibleFunc
Sets the visible function used when filtering the filter to be func. The
function should return TRUE if the given row should be visible and
FALSE otherwise.

User data to pass to the visible function, or |
If the condition calculated by the function changes over time (e.g. because
it depends on some global parameters), you must call
gtkTreeModelFilterRefilter to keep the visibility information of
the model uptodate.
Note that func is called whenever a row is inserted, when it may still be
empty. The visible function should therefore take special care of empty
rows, like in the example below.
visible_func <- function(model, iter, data)
{
## Visible if row is non-empty and first column is "HI"
visible <- FALSE
str <- model$get(iter, 0)[[1]]
if (identical(str, "HI"))
visible <- TRUE
return(visible)
}Since 2.4
