GtkToolItem

typedef struct _GtkToolItem GtkToolItem;

The GtkToolItem struct contains only private data. It should only be accessed through the functions described below.

gtk_tool_item_new ()

GtkToolItem* gtk_tool_item_new              (void);

Creates a new GtkToolItem

Since 2.4

gtk_tool_item_set_homogeneous ()

void        gtk_tool_item_set_homogeneous   (GtkToolItem *tool_item,
                                             gboolean homogeneous);

Sets whether tool_item is to be allocated the same size as other homogeneous items. The effect is that all homogeneous items will have the same width as the widest of the items.

Since 2.4

gtk_tool_item_get_homogeneous ()

gboolean    gtk_tool_item_get_homogeneous   (GtkToolItem *tool_item);

Returns whether tool_item is the same size as other homogeneous items. See gtk_tool_item_set_homogeneous().

                                             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.

Since 2.4

gtk_tool_item_get_expand ()

gboolean    gtk_tool_item_get_expand        (GtkToolItem *tool_item);

Returns whether tool_item is allocated extra space. See gtk_tool_item_set_expand().

                                             GtkTooltips *tooltips,
                                             const gchar *tip_text,
                                             const gchar *tip_private);

Sets the GtkTooltips object to be used for tool_item, the text to be displayed as tooltip on the item and the private text to be used. See gtk_tooltips_set_tip().

                                             gboolean use_drag_window);

Sets whether toolitem has a drag window. When TRUE the toolitem can be used as a drag source through gtk_drag_source_set(). When toolitem has a drag window it will intercept all events, even those that would otherwise be sent to a child of toolitem.

Since 2.4

gtk_tool_item_get_use_drag_window ()

gboolean    gtk_tool_item_get_use_drag_window

                                            (GtkToolItem *toolitem);

Returns whether the toolitem is visible on toolbars that are docked horizontally.

Since 2.4

gtk_tool_item_set_visible_vertical ()

void        gtk_tool_item_set_visible_vertical
                                            (GtkToolItem *toolitem,
                                             gboolean visible_vertical);

Since 2.4

gtk_tool_item_get_visible_vertical ()

gboolean    gtk_tool_item_get_visible_vertical
                                            (GtkToolItem *toolitem);

gtk_tool_item_set_is_important ()

void        gtk_tool_item_set_is_important  (GtkToolItem *tool_item,
                                             gboolean is_important);

Sets whether tool_item should be considered important. The GtkToolButton class uses this property to determine whether to show or hide its label when the toolbar style is GTK_TOOLBAR_BOTH_HORIZ. The result is that only tool buttons with the "is_important" property set have labels, an effect known as "priority text"

Since 2.4

gtk_tool_item_get_is_important ()

gboolean    gtk_tool_item_get_is_important  (GtkToolItem *tool_item);

Returns whether tool_item is considered important. See gtk_tool_item_set_is_important()

Since 2.4

gtk_tool_item_get_icon_size ()

GtkIconSize gtk_tool_item_get_icon_size     (GtkToolItem *tool_item);

Returns the icon size used for tool_item. Custom subclasses of GtkToolItem should call this function to find out what size icons they should use.

Since 2.4

gtk_tool_item_get_orientation ()

GtkOrientation gtk_tool_item_get_orientation
                                            (GtkToolItem *tool_item);

Returns the orientation used for tool_item. Custom subclasses of GtkToolItem should call this function to find out what size icons they should use.

Since 2.4

gtk_tool_item_get_toolbar_style ()

GtkToolbarStyle gtk_tool_item_get_toolbar_style
                                            (GtkToolItem *tool_item);

Returns the toolbar style used for tool_item. Custom subclasses of GtkToolItem should call this function in the handler of the GtkToolItem::toolbar_reconfigured signal to find out in what style the toolbar is displayed and change themselves accordingly

Possibilities are:

Since 2.4

gtk_tool_item_get_relief_style ()

GtkReliefStyle gtk_tool_item_get_relief_style
                                            (GtkToolItem *tool_item);

Returns the relief style of tool_item. See gtk_button_set_relief_style(). Custom subclasses of GtkToolItem should call this function in the handler of the GtkToolItem::toolbar_reconfigured signal to find out the relief style of buttons.

Since 2.4

gtk_tool_item_retrieve_proxy_menu_item ()

GtkWidget*  gtk_tool_item_retrieve_proxy_menu_item
                                            (GtkToolItem *tool_item);

Returns the GtkMenuItem that was last set by gtk_tool_item_set_proxy_menu_item(), ie. the GtkMenuItem that is going to appear in the overflow menu.

Since 2.4

gtk_tool_item_get_proxy_menu_item ()

GtkWidget*  gtk_tool_item_get_proxy_menu_item
                                            (GtkToolItem *tool_item,
                                             const gchar *menu_item_id);

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.

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().

Since 2.4

gtk_tool_item_rebuild_menu ()

void        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

The "is-important" property

  "is-important"         gboolean              : Read / Write

Whether the toolbar item is considered important. When TRUE, toolbar buttons show text in GTK_TOOLBAR_BOTH_HORIZ mode.

Default value: FALSE

The "visible-horizontal" property

  "visible-horizontal"   gboolean              : Read / Write

Whether the toolbar item is visible when the toolbar is in a horizontal orientation.

Default value: TRUE

The "visible-vertical" property

  "visible-vertical"     gboolean              : Read / Write

Whether the toolbar item is visible when the toolbar is in a vertical orientation.

Default value: TRUE

The "create-menu-proxy" signal

gboolean    user_function                  (GtkToolItem *toolitem,
                                            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

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.

The "set-tooltip" signal

gboolean    user_function                  (GtkToolItem *toolitem,
                                            GtkTooltips *tooltips,
                                            gchar *tip_text,
                                            gchar *tip_private,
                                            gpointer user_data);

This signal is emitted when the toolitem's tooltip changes. Application developers can use gtk_tool_item_set_tooltip() to set the item's tooltip.

The "toolbar-reconfigured" signal

void        user_function                  (GtkToolItem *toolitem,
                                            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

to find out what the toolbar should look like and change themselves accordingly.
