Implemented Interfaces

GtkTree implements AtkImplementorIface and GtkBuildable.

Includes

#include <gtk/gtk.h>

Description

GtkTree is deprecated and unsupported. It is known to be buggy. To use it, you must define the symbol GTK_ENABLE_BROKEN prior to including the GTK+ header files. Use GtkTreeView instead.

The GtkTree widget is a container that shows users a list of items, in a tree format complete with branches and leafnodes. Branches can be expanded to show their child items, or collapsed to hide them.

Functions

GTK_IS_ROOT_TREE()

#define GTK_IS_ROOT_TREE(obj)   ((GtkObject*) GTK_TREE(obj)->root_tree == (GtkObject*)obj)

GTK_IS_ROOT_TREE is deprecated and should not be used in newly-written code.

A macro that returns a boolean value which indicates if obj is a root tree or not.

Parameters

obj

A pointer to the GtkTree. obj will accept any pointer, but if the pointer does not point to a GtkTree, the results are undefined.

GTK_TREE_ROOT_TREE()

#define GTK_TREE_ROOT_TREE(obj) (GTK_TREE(obj)->root_tree ? GTK_TREE(obj)->root_tree : GTK_TREE(obj))

GTK_TREE_ROOT_TREE is deprecated and should not be used in newly-written code.

A macro that returns the root tree of obj.

If obj is already a root tree, obj is cast to GtkTree and returned.

Parameters

obj

A pointer to the GtkTree. obj will accept any pointer, but if the pointer does not point to a GtkTree, the results are undefined.

GTK_TREE_SELECTION_OLD()

#define GTK_TREE_SELECTION_OLD(obj) (GTK_TREE_ROOT_TREE(obj)->selection)

GTK_TREE_SELECTION_OLD is deprecated and should not be used in newly-written code.

gtk_tree_new ()

GtkWidget *
gtk_tree_new (void);

gtk_tree_new is deprecated and should not be used in newly-written code.

Creates a new GtkTree.

Returns

A pointer to the newly allocated widget.

gtk_tree_append ()

void
gtk_tree_append (GtkTree *tree,
                 GtkWidget *tree_item);

gtk_tree_append is deprecated and should not be used in newly-written code.

Adds the GtkTreeItem in tree_item to the end of the items in tree.

Parameters

tree	A pointer to a GtkTree.
tree_item	A pointer to the GtkWidget that is to be appended to the tree.

gtk_tree_prepend ()

void
gtk_tree_prepend (GtkTree *tree,
                  GtkWidget *tree_item);

gtk_tree_prepend is deprecated and should not be used in newly-written code.

Adds the GtkTreeItem in tree_item to the start of the items in tree.

Parameters

tree	A pointer to a GtkTree.
tree_item	A pointer to the GtkWidget that is to be prepended to the tree.

gtk_tree_insert ()

void
gtk_tree_insert (GtkTree *tree,
                 GtkWidget *tree_item,
                 gint position);

gtk_tree_insert is deprecated and should not be used in newly-written code.

Adds the GtkTreeItem in tree_item to the list of items in tree at the position indicated by position.

Parameters

tree	A pointer to a GtkTree.
tree_item	A pointer to the GtkWidget that is to be added to the tree.
position	A gint that indicates the position in the tree, that the `tree_item` is to be added at.

gtk_tree_remove_items ()

void
gtk_tree_remove_items (GtkTree *tree,
                       GList *items);

gtk_tree_remove_items is deprecated and should not be used in newly-written code.

Removes a list of items from the GtkTree in tree.

If only one item is to be removed from the GtkTree, gtk_container_remove() can be used instead.

Removing an item from a GtkTree dereferences the item, and thus usually destroys the item and any subtrees it may contain. If the item is not to be destroyed, use g_object_ref() before removing it.

Parameters

tree	A pointer to a GtkTree.
items	A pointer to a GList that contains the items to be removed.

gtk_tree_clear_items ()

void
gtk_tree_clear_items (GtkTree *tree,
                      gint start,
                      gint end);

gtk_tree_clear_items is deprecated and should not be used in newly-written code.

Removes the items at positions between start and end from the GtkTree tree.

Removing an item from a GtkTree dereferences the item, and thus usually destroys the item and any subtrees it may contain. If the item is not to be destroyed, use g_object_ref() before removing it.

Parameters

tree	A pointer to a GtkTree.
start	A gint.
end	A gint.

gtk_tree_select_item ()

void
gtk_tree_select_item (GtkTree *tree,
                      gint item);

gtk_tree_select_item is deprecated and should not be used in newly-written code.

Emits the select_item signal for the child at position item, and thus selects it (unless it is unselected in a signal handler).

Parameters

tree	A pointer to a GtkTree.
item	A gint.

gtk_tree_unselect_item ()

void
gtk_tree_unselect_item (GtkTree *tree,
                        gint item);

gtk_tree_unselect_item is deprecated and should not be used in newly-written code.

Emits the unselect_item for the child at position item, and thus unselects it.

Parameters

tree	A pointer to a GtkTree.
item	A gint.

gtk_tree_select_child ()

void
gtk_tree_select_child (GtkTree *tree,
                       GtkWidget *tree_item);

gtk_tree_select_child is deprecated and should not be used in newly-written code.

Emits the select_item signal for the child tree_item, and thus selects it (unless it is unselected in a signal handler).

Parameters

tree	A pointer to a GtkTree.
tree_item	A pointer to the GtkWidget that is to be selected.

gtk_tree_unselect_child ()

void
gtk_tree_unselect_child (GtkTree *tree,
                         GtkWidget *tree_item);

gtk_tree_unselect_child is deprecated and should not be used in newly-written code.

Emits the unselect_item signal for the child tree_item, and thus unselects it.

Parameters

tree	A pointer to a GtkTree.
tree_item	A pointer to the GtkWidget that is to be selected.

gtk_tree_child_position ()

gint
gtk_tree_child_position (GtkTree *tree,
                         GtkWidget *child);

gtk_tree_child_position is deprecated and should not be used in newly-written code.

Returns the position of child in the GtkTree tree.

If child is not a child of tree, then -1 is returned.

Parameters

tree	A pointer to a GtkTree.
child	A pointer to a GtkWidget.

Returns

A gint.

gtk_tree_set_selection_mode ()

void
gtk_tree_set_selection_mode (GtkTree *tree,
                             GtkSelectionMode mode);

gtk_tree_set_selection_mode is deprecated and should not be used in newly-written code.

GTK_SELECTION_BROWSE for when one item must be selected.
GTK_SELECTION_MULTIPLE for when many items can be selected at once.
GTK_SELECTION_EXTENDED Reserved for later use.

The selection mode is only defined for a root tree, as the root tree "owns" the selection.

The default mode is GTK_SELECTION_SINGLE.

Sets the 'viewmode' for the GtkTree in tree. The 'viewmode' defines how the tree looks when an item is selected.

mode can be one of:

GTK_TREE_VIEW_LINE : When an item is selected the entire GtkTreeItem is highlighted.
GTK_TREE_VIEW_ITEM : When an item is selected only the selected item's child widget is highlighted.

The default mode is GTK_TREE_VIEW_LINE.

Parameters

tree	A pointer to a GtkTree.
mode	A GtkTreeViewMode.
