Description
GtkToolItems are widgets that can appear on a toolbar. To create a toolbar item that contain something else than a button, use gtk_tool_item_new()
. Use gtk_container_add()
to add a child widget to the tool item.
For toolbar items that contain buttons, see the GtkToolButton, GtkToggleToolButton and GtkRadioToolButton classes.
See the GtkToolbar class for a description of the toolbar widget, and GtkToolShell for a description of the tool shell interface.
Functions
gtk_tool_item_new ()
GtkToolItem *
gtk_tool_item_new (void
);
Creates a new GtkToolItem
Returns
the new GtkToolItem

gtk_tool_item_set_homogeneous ()
void gtk_tool_item_set_homogeneous (GtkToolItem *tool_item
,gboolean homogeneous

homogeneous | whether |
Since: 2.4
gtk_tool_item_get_homogeneous ()
gboolean
gtk_tool_item_get_homogeneous (GtkToolItem *tool_item

Returns
TRUE
if the item is the same size as other homogeneous items.
Since: 2.4
gtk_tool_item_set_expand ()
void gtk_tool_item_set_expand (GtkToolItem *tool_item
,gboolean expand
);
Sets whether tool_item
is allocated extra space when there is more room on the toolbar then needed for the items. The effect is that the item gets bigger when the toolbar gets bigger and smaller when the toolbar gets smaller.
Parameters
tool_item | ||
expand | Whether |
Since: 2.4
gtk_tool_item_get_expand ()
gboolean
gtk_tool_item_get_expand (GtkToolItem *tool_item

.
Parameters

Since: 2.4
gtk_tool_item_get_use_drag_window ()
gboolean
gtk_tool_item_get_use_drag_window (GtkToolItem *tool_item

gtk_tool_item_get_proxy_menu_item ()
GtkWidget * gtk_tool_item_get_proxy_menu_item (GtkToolItem *tool_item

);
If menu_item_id
matches the string passed to gtk_tool_item_set_proxy_menu_item()
return the corresponding GtkMenuItem.
Custom subclasses of GtkToolItem should use this function to update their menu item when the GtkToolItem changes. That the menu_item_ids
must match ensures that a GtkToolItem will not inadvertently change a menu item that they did not create.
Parameters
tool_item | ||
menu_item_id | a string used to identify the menu item |
Returns
The GtkMenuItem passed to gtk_tool_item_set_proxy_menu_item()
, if the menu_item_ids
match.
[transfer none][nullable]
Since: 2.4
gtk_tool_item_set_proxy_menu_item ()
void gtk_tool_item_set_proxy_menu_item (GtkToolItem *tool_item
,const gchar *menu_item_id
,GtkWidget *menu_item
);
Sets the GtkMenuItem used in the toolbar overflow menu. The menu_item_id
is used to identify the caller of this function and should also be used with gtk_tool_item_get_proxy_menu_item()
.
See also “create-menu-proxy”.
Parameters
tool_item | ||
menu_item_id | a string used to identify | |
menu_item | a GtkMenuItem to use in the overflow menu, or | [nullable] |
Since: 2.4
gtk_tool_item_rebuild_menu ()

gtk_tool_item_rebuild_menu (GtkToolItem *tool_item
);
Calling this function signals to the toolbar that the overflow menu item for tool_item
has changed. If the overflow menu is visible when this function it called, the menu will be rebuilt.
The function must be called when the tool item changes what it will do in response to the “create-menu-proxy” signal.

Since: 2.6
gtk_tool_item_toolbar_reconfigured ()
void
gtk_tool_item_toolbar_reconfigured (GtkToolItem *tool_item

. GtkToolbar and other GtkToolShell implementations use this function to notify children, when some aspect of their configuration changes.
Parameters
tool_item |
Since: 2.14
gtk_tool_item_get_text_size_group ()
GtkSizeGroup *
gtk_tool_item_get_text_size_group (GtkToolItem *tool_item

Since: 2.20
Types and Values
struct GtkToolItem
struct GtkToolItem;
The GtkToolItem struct contains only private data. It should only be accessed through the functions described below.
struct GtkToolItemClass
struct GtkToolItemClass { GtkBinClass parent_class; /* signals */ gboolean (* create_menu_proxy) (GtkToolItem *tool_item); void (* toolbar_reconfigured) (GtkToolItem *tool_item); };
Members
| Signal emitted when the toolbar needs information from tool_item about whether the item should appear in the toolbar overflow menu. | |
| Signal emitted when some property of the toolbar that the item is a child of changes. |
Property Details
The “is-important”
property
“is-important” gboolean
Whether the toolbar item is considered important. When TRUE, toolbar buttons show text in GTK_TOOLBAR_BOTH_HORIZ mode.
Owner: GtkToolItem
Flags: Read / Write
Default value: FALSE
The “visible-horizontal”
property
“visible-horizontal” gboolean
Whether the toolbar item is visible when the toolbar is in a horizontal orientation.
Owner: GtkToolItem
Flags: Read / Write
Default value: TRUE
The “visible-vertical”
property
“visible-vertical” gboolean
Whether the toolbar item is visible when the toolbar is in a vertical orientation.
Owner: GtkToolItem
Flags: Read / Write
Default value: TRUE
Signal Details
The “create-menu-proxy”
signal
gboolean user_function (GtkToolItem *tool_item, gpointer user_data)
This signal is emitted when the toolbar needs information from tool_item
about whether the item should appear in the toolbar overflow menu. In response the tool item should either
call
gtk_tool_item_set_proxy_menu_item()
with aNULL
pointer and returnTRUE
to indicate that the item should not appear in the overflow menucall
gtk_tool_item_set_proxy_menu_item()
with a new menu item and returnTRUE
, orreturn
FALSE
to indicate that the signal was not handled by the item. This means that the item will not appear in the overflow menu unless a later handler installs a menu item.
The toolbar may cache the result of this signal. When the tool item changes how it will respond to this signal it must call gtk_tool_item_rebuild_menu()
to invalidate the cache and ensure that the toolbar rebuilds its overflow menu.
Parameters
tool_item | the object the signal was emitted on | |
user_data | user data set when the signal handler was connected. |
Returns
TRUE
if the signal was handled, FALSE
if not
Flags: Run Last
The “toolbar-reconfigured”
signal
void user_function (GtkToolItem *tool_item, gpointer user_data)
This signal is emitted when some property of the toolbar that the item is a child of changes. For custom subclasses of GtkToolItem, the default handler of this signal use the functions
gtk_tool_shell_get_orientation()
gtk_tool_shell_get_style()
gtk_tool_shell_get_icon_size()
gtk_tool_shell_get_relief_style() to find out what the toolbar should look like and change themselves accordingly.
Parameters
tool_item | the object the signal was emitted on | |
user_data | user data set when the signal handler was connected. |
Flags: Run Last
