Function

Gtk.TreeModelFilterModifyFunc

Declaration

void
TreeModelFilterModifyFunc (
  GtkTreeModel* model,
  GtkTreeIter* iter,
  GValue* value,
  int column,
  gpointer data
)

Description

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.

`iter`	`GtkTreeIter`
	a `GtkTreeIter` pointing to the row whose display values are determined

`value`	`GValue*`
	A `GValue` which is already initialized for with the correct type for the column `column`.
	Direction: out
	Ownership is not transferred
`column`	`int`
	the column whose display value is determined
`data`	`gpointer`
	user data given to `gtk_tree_model_filter_set_modify_func()`
