Function

GtkTreeModelFilterModifyFunc

Declaration

void
(* GtkTreeModelFilterModifyFunc) (
  GtkTreeModel* model,
  GtkTreeIter* iter,
  GValue* value,
  gint column,
  gpointer data
)

Description [src]

A function which calculates display values from raw values in the model. It must fill value with the display value for the column column in the row indicated by iter.

Since this function is called for each data access, it’s not a particularly efficient operation.
