GI.Gtk.Structs.TreeIter

The TreeIter is the primary structure for accessing a TreeModel. Models are expected to put a unique integer in the stamp member, and put model-specific data in the three userData members.

Methods

overloadedMethod :: MethodProxy TreeIterCopyMethodInfo TreeIter -> signature -> s

treeIterCopy

Arguments

:: (HasCallStack, MonadIO m)

=> TreeIter

iter: a TreeIter-struct

-> m TreeIter

Returns: a newly-allocated copy of iter

Creates a dynamically allocated tree iterator as a copy of iter.

This function is not intended for use in applications, because you can just copy the structs by value (GtkTreeIter new_iter = iter;). You must free this iter with treeIterFree.

Methods

overloadedMethod :: MethodProxy TreeIterFreeMethodInfo TreeIter -> signature -> s

treeIterFree

Arguments

:: (HasCallStack, MonadIO m)

=> TreeIter

iter: a dynamically allocated tree iterator

-> m ()

Frees an iterator that has been allocated by treeIterCopy.

This function is mainly used for language bindings.
