Asks the GtkTreeDragSource to delete the row at path, because
it was moved somewhere else via drag-and-drop. Returns FALSE
if the deletion fails because path no longer exists, or for
some model-specific reason. Should robustly handle a path no
longer found in the model!

Parameters:

Gtk.TreePath path Required (not null)

row that was being dragged

Returns:

gboolean TRUE if the row was successfully deleted

Asks the GtkTreeDragSource to fill in selection_data with a

Parameters:

Gtk.TreeIter iter Required (not null)

A GtkTreeIter.

Gtk.TreeIter position

A GtkTreeIter or NULL.

Returns:

none

is called on a builder.

Parameters:

Gtk.Builder builder Required (not null)

a GtkBuilder

Returns:

none

Prepends a new row to list_store. iter will be changed to point to this new
row. The row will be empty after this function is called. To fill in
values, you need to call gtk_list_store_set() or gtk_list_store_set_value().

Returns:

Gtk.TreeIter

Lets the tree ref the node.
This is an optional method for models to implement.
To be more specific, models may ignore this call as it exists
primarily for performance reasons.
This function is primarily meant as a way for views to let
caching models know when nodes are being displayed (and hence,
whether or not to cache that node). For example, a file-system
based model would not want to keep the entire file-hierarchy in
memory, just the sections that are currently being displayed by
every current view.
A model should be expected to be able to get an iter independent
of its reffed state.

Parameters:

Gtk.TreeIter iter Required (not null)

the GtkTreeIter

Returns:

none

Removes the given row from the list store. After being removed,
to the last row in list_store.

Parameters:

Parameters:

Gtk.TreePath path Required (not null)

a GtkTreePath pointing to the changed row

Gtk.TreeIter iter Required (not null)

a valid GtkTreeIter pointing to the changed row

Returns:

none

Emits the GtkTreeModel::row-deleted signal on tree_model.
This should be called by models after a row has been removed.
The location pointed to by path should be the location that
the row previously was at. It may not be a valid location anymore.

Parameters:

Gtk.TreePath path Required (not null)

a GtkTreePath pointing to the previous location of the deleted row

Returns:

none

Asks the GtkTreeDragSource whether a particular row can be used as
the source of a DND operation. If the source doesn't implement
this interface, the row is assumed draggable.

Parameters:

Gtk.TreePath path Required (not null)

row on which user is initiating a drag

Returns:

gboolean TRUE if the row can be dragged

Determines whether a drop is possible before the given dest_path,
at the same depth as dest_path. i.e., can we drop the data in
exist; the return value will almost certainly be FALSE if the
parent of dest_path doesn't exist, though.

Parameters:

Gtk.TreePath dest_path Required (not null)

destination row

Gtk.SelectionData selection_data Required (not null)

the data being dragged

Returns:

gboolean TRUE if a drop is possible before dest_path

a valid GtkTreeIter pointing to the inserted row

Returns:

none

Sets the value of one or more cells in the row referenced by iter.
The variable argument list should contain integer column numbers,
each column number followed by the value to be set.
The list is terminated by a -1. For example, to set column 0 with type
G_TYPE_STRING to "Foo", you would write gtk_list_store_set (store, iter,
0, "Foo", -1).
The value will be referenced by the store if it is a G_TYPE_OBJECT, and it
will be copied if it is a G_TYPE_STRING or G_TYPE_BOXED.

Parameters:

Gtk.TreeIter iter Required (not null)

row iterator

Array columns Required (not null)

Array values Required (not null)

gint32 n_values Required (not null)

Returns:

none

This function is meant primarily for GObjects that inherit from GtkListStore,
and should only be used when constructing a new GtkListStore. It will not
function after a row has been added, or a method on the GtkTreeModel
interface is called.

If the current sort column id of sortable is
GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID, then the model will sort using
this function.
If sort_func is NULL, then there will be no default comparison function.
This means that once the model has been sorted, it can't go back to the
default state. In this case, when the current sort column id of sortable
is GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID, the model will be unsorted.

Parameters:

Function (TreeModel model, TreeIter a, TreeIter b, void* user_data) : none Required (not null)

The comparison function

void* user_data

User data to pass to sort_func, or NULL

Function (void* data) : none

Returns:

none

Sets the name of the buildable object.

Parameters:

String name Required (not null)

name to set

Returns:

none

Sets the current sort column to be sort_column_id. The sortable will
resort itself to reflect this change, after emitting a
GtkTreeSortable::sort-column-changed signal. sort_column_id may either be
a regular column id, or one of the following special values:


GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID
the default sort function will be used, if it is set


GTK_TREE_SORTABLE_UNSORTED_SORT_COLUMN_ID
no sorting will occur

Parameters:

gint32 sort_column_id Required (not null)

the sort column id to set

Gtk.SortType order Required (not null)

User data to pass to sort_func, or NULL

Function (void* data) : none

Destroy notifier of user_data, or NULL

Returns:

none

Sets the data in the cell specified by iter and column.
The type of value must be convertible to the type of the
column.

Another GtkTreeIter.

Returns:

none

Lets the tree unref the node.
This is an optional method for models to implement.
To be more specific, models may ignore this call as it exists
primarily for performance reasons. For more information on what
this means, see gtk_tree_model_ref_node().
Please note that nodes that are deleted are not unreffed.

Parameters:

Gtk.TreeIter iter Required (not null)

the GtkTreeIter

Returns:

none

This signal is emitted when a row in the model has changed.

Parameters:

Gtk.TreeModel self

Gtk.TreePath path

Gtk.TreeIter iter

Returns:

{none}

This signal is emitted when a row has been deleted.
Note that no iterator is passed to the signal handler,
since the row is already deleted.
This should be called by models after a row has been removed.
The location pointed to by path should be the location that
the row previously was at. It may not be a valid location anymore.

Parameters:

Gtk.TreeModel self

Gtk.TreePath path

Returns:

{none}

This signal is emitted when a row has gotten the first child
row or lost its last child row.

Parameters:

Gtk.TreeModel self

Gtk.TreePath path

Gtk.TreeIter iter

Returns:

{none}

This signal is emitted when a new row has been inserted in
the model.
Note that the row may still be empty at this point, since
it is a common pattern to first insert an empty row, and
then fill it with the desired values.

Parameters:

Gtk.TreeModel self

Gtk.TreePath path

Gtk.TreeIter iter

Returns:

{none}
