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.

	The `GtkTreeModelFilter`.
	The data is owned by the caller of the function.
`iter`	`GtkTreeIter`
	A `GtkTreeIter` pointing to the row whose display values are determined.
	The data is owned by the caller of the function.
`value`	`GValue`
	A `GValue` which is already initialized for with the correct type for the column `column`.
	The argument will be set by the function.
	The data is owned by the caller of the function.
`column`	`gint`
	The column whose display value is determined.
`data`	`gpointer`
