Detailed Description

A GtkToolItem C++ wrapper class.

ToolItems are widgets that can appear on a toolbar. To construct a toolbar item that contains something other than a button, use ToolItem(). Use Gtk::Container::add() to add a child widget to the tool item.

For toolbar items that contain buttons, see the Gtk::ToolButton, Gtk::ToggleToolButton and Gtk::RadioToolButton classes. See the Gtk::Toolbar class for a description of the toolbar widget.

See also: the ToolItems HOWTO.

Returns:
true if the tool item is considered important.

IconSize Xfc::Gtk::ToolItem::get_icon_size (  )  const

Gets the icon size used for the tool item.

Returns:
A Gtk::IconSize indicating the icon size used for the tool item.
Custom subclasses of ToolItem should call this function to find out what size icons they should use.

Orientation Xfc::Gtk::ToolItem::get_orientation (  )  const

Gets the orientation used for the tool item.

Returns:
A Gtk::Orientation indicating the orientation used for the tool item.
Custom subclasses of ToolItem should call this function to find out the orientation of they should use.

ToolbarStyle Xfc::Gtk::ToolItem::get_toolbar_style (  )  const

Gets the toolbar style used for the tool item.

Returns:
A Gtk::ToolbarStyle indicating the toolbar style used for the tool item.
Custom subclasses of ToolItem should call this function in the handler of the ToolItem "toolbar_reconfigured" signal to find out in what style the toolbar is displayed and change themselves accordingly. The possibilities are: Gtk::TOOLBAR_BOTH, meaning the tool item should show both an icon and a label, stacked vertically, Gtk::TOOLBAR_ICONS, meaning the toolbar shows only icons, Gtk::TOOLBAR_TEXT, meaning the tool item should only show text and Gtk::TOOLBAR_BOTH_HORIZ, meaning the tool item should show both an icon and a label, arranged horizontally.

ReliefStyle Xfc::Gtk::ToolItem::get_relief_style (  )  const

Gets the relief style of the tool item (see set_relief_style().

Returns:
A Gtk::ReliefStyle indicating the relief style used for the tool item.
Custom subclasses of ToolItem should call this function in the handler of the ToolItem "toolbar_reconfigured" signal to find out the relief style of the buttons.

Widget* Xfc::Gtk::ToolItem::get_proxy_menu_item ( const String menu_item_id  )  const

If menu_item_id matches the string passed to set_proxy_menu_item() returns the corresponding Gtk::MenuItem widget.

Parameters:
menu_item_id A string used to identify the menu item.
Returns:
The MenuItem passed to set_proxy_menu_item(), if the menu_item_ids match.
Custom subclasses of ToolItem should use this function to update their menu item when the ToolItem changes. That the menu_item_ids must match ensures that a ToolItem will not inadvertently change a menu item that they did not create.

Widget* Xfc::Gtk::ToolItem::retrieve_proxy_menu_item (  )  const

Retrieves the MenuItem that was last set by set_proxy_menu_item(), that is, the MenuItem that is going to appear in the overflow menu.

Returns:
The MenuItem that is going to appear in the overflow menu for the tool item.

void Xfc::Gtk::ToolItem::set_homogeneous ( bool  homogeneous  ) 

Sets whether the tool item is to be allocated the same size as other homogeneous items.

Parameters:
homogeneous Whether the tool item is 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.

void Xfc::Gtk::ToolItem::set_expand ( bool  expand  ) 

Sets whether the tool item is allocated extra space when there is more room on the toolbar than needed for the items.

Parameters:
expand Whether the tool item is allocated extra space.
The effect is that the item gets bigger when the toolbar gets bigger and smaller when the toolbar gets smaller.

void Xfc::Gtk::ToolItem::set_tooltip ( Tooltips tooltips,
const String tip_text,
const String tip_private = 0 
)

Sets the Tooltips object to be used for the tool item, the text to be displayed as tooltip on the item and the private text to be used (see Gtk::Tooltips::set_tip()).

Parameters:
tooltips The Tooltips object to be used.
tip_text The text to be used as tooltip text for the tool item.
tip_private The text to be used as private tooltip text.

void Xfc::Gtk::ToolItem::set_use_drag_window ( bool  use_drag_window  ) 

Sets whether toolitem has a drag window.

Parameters:
use_drag_window Whether the tool item has a drag window.
When use_drag_window is true the tool item can be used as a drag source through Gtk::Widget::drag_source_set(). When the tool item has a drag window it will intercept all events, even those that would otherwise be sent to a child of toolitem.

void Xfc::Gtk::ToolItem::set_visible_horizontal ( bool  visible_horizontal  ) 

Sets whether the tool item is visible when the toolbar is docked horizontally.

Parameters:
visible_horizontal Whether the tool item is visible when in horizontal mode.

void Xfc::Gtk::ToolItem::set_visible_vertical ( bool  visible_vertical  ) 

Sets whether the tool item is visible when the toolbar is docked vertically.

Parameters:
visible_vertical Whether the tool item is visible when the toolbar is in vertical mode.
Some tool items, such as text entries, are too wide to be useful on a vertically docked toolbar. If visible_vertical is false the tool item will not appear on toolbars that are docked vertically.

void Xfc::Gtk::ToolItem::set_is_important ( bool  is_important  ) 

Sets whether the tool item should be considered important.

Parameters:
is_important Whether the tool item should be considered important.
The ToolButton 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".

void Xfc::Gtk::ToolItem::set_proxy_menu_item ( const String menu_item_id,
Widget menu_item 
)

Sets the MenuItem used in the toolbar overflow menu.

Parameters:
menu_item_id A string used to identify menu_item.
menu_item A MenuItem to be used in the overflow menu.
The menu_item_id is used to identify the caller of this function and should also be used with get_proxy_menu_item(). If menu_item is null the MenuItem last set will not appear in the overflow menu (see signal_create_menu_proxy()).

void Xfc::Gtk::ToolItem::rebuild_menu (  ) 

Calling this method signals to the toolbar that the overflow menu item for the tool item has changed.

If the overflow menu is visible when this function it called, the menu will be rebuilt.

This function must be called when the tool item changes what it will do in response to the "create_menu_proxy" signal.

const CreateMenuProxySignalProxy Xfc::Gtk::ToolItem::signal_create_menu_proxy (  ) 

Connect to the create_menu_proxy_signal; emitted when the toolbar is displaying an overflow menu.

In response the tool item should call Gtk::ToolItem::set_proxy_menu_item() with either with a null pointer and return true to indicate that the item should not appear in the overflow menu, or with a new menu item and return true, or return 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.

const ToolbarReconfiguredSignalProxy Xfc::Gtk::ToolItem::signal_toolbar_reconfigured (  ) 

Connect to the toolbar_reconfigured_signal; emitted when some property of the toolbar that the item is a child of changes.

For custom subclasses of Gtk::ToolItem, the default handler of this signal uses the functions Gtk::Toolbar::get_orientation(), Gtk::Toolbar::get_style(), Gtk::Toolbar::get_icon_size() and Gtk::Toolbar::get_relief_style() to find out what the toolbar should look like and change themselves accordingly.
