public delegate bool TreeViewRowSeparatorFunc (TreeModel model, TreeIter iter)
Function type for determining whether the row pointed to by iter should be rendered as a separator.
A common way to implement this is to have a boolean column in the model, whose values the `GtkTreeViewRowSeparatorFunc` returns.
| model |
the `GtkTreeModel` |
| iter |
a `GtkTreeIter` pointing at a row in |
| data |
user data |
|
true if the row is a separator |
