   HIToolbarItemRef inItem,
   WindowRef inWindow,
   OptionBits inAttrsToSet,
   OptionBits inAttrsToClear,
   OptionBits inAttrsToNoLongerOverride
);

Parameters

inItem: The item in question.
inWindow: The window containing the item in question.
inAttrsToSet: The attributes to set on the item. For possible attributes, see “Toolbar Item Attributes.” Use kHIToolbarItemNoAttributes if you are clearing attributes and have no attributes to set.
inAttrsToClear: The attributes to clear on the item. This value can be kHIToolbarItemNoAttributes if you are setting attributes and have no attributes to clear.
inAttrsToNoLongerOverride: The attributes that are to no longer be overridden. Calling this function causes the attributes to be removed from the override mask for the toolbar item in the specified window. Their effective values revert to their non-window-specific attribute values.

Return Value

An operating system result code.

Discussion

This function allows the attributes of a toolbar item in the specified window to be overridden. The attributes used to draw the view of a toolbar item in a particular window are determined by combining the non-window-specific attributes for the item set by HIToolbarItemChangeAttributes with the window-specific attributes set by this function. As a result, your application can have a toolbar that is shared across several windows with a toolbar item that is enabled in one window and disabled in another window.

When HIToolbarItemChangeAttributesInWindow is called to set or clear attributes, the toolbar item adds the changed attributes to a bitmask of attributes, thereby recording which attributes are overridden for a particular window. Once an attribute is overridden for a window (regardless of whether the attribute is set or cleared), the attribute remains overridden for that window until HIToolbarItemChangeAttributesInWindow is called with that attribute specified in the inAttrsToNoLongerOverride parameter.

Only those attributes defined by the kHIToolbarItemMutableAttrs constant can be passed into this function. For details, see “Toolbar Item Attributes.”

Parameters

inItem: The item whose configuration changed.

Return Value

An operating system result code.

Discussion

This function tells the toolbar that the config data for a toolbar item has changed and should be written to the toolbar configuration preferences. This function is used when a custom toolbar item has extra configuration data that has changed (for example, you’ve changed an alias that a toolbar item points to). This function does nothing if the toolbar is not set to auto-save its configuration.

   kEventToolbarEndMultiChange = 13
};

Constants

kEventToolbarGetDefaultIdentifiers

This event is sent to the delegate to get a list of all of the default item identifiers that should be created for a toolbar. You are passed a mutable array to fill in with the identifiers. (

Available in Mac OS X v10.2.)

Declared in HIToolbar.h.

kEventToolbarGetAllowedIdentifiers

This event is sent to the delegate to get a list of all the items which could possibly be added to the toolbar. This is sent out when the configuration sheet is about to be displayed.You are passed a mutable array to fill in with the identifiers. (

Available in Mac OS X v10.2.)

Declared in HIToolbar.h.

kEventToolbarCreateItemWithIdentifier

This event is sent to the delegate to when the toolbar needs to create an item from an identifier. (

Available in Mac OS X v10.2.)

Declared in HIToolbar.h.

kEventToolbarCreateItemFromDrag

This event is sent to the delegate to when the toolbar needs to create an item from a drag. This allows you to be able to drag items into a toolbar that aren’t normal toolbar items. You might use this to allow your toolbar to accept file system items, for example. (

Declared in HIToolbar.h.

Available in Mac OS X v10.2.)

kEventToolbarItemAdded

This event is sent when an item is added to the toolbar. The toolbar object sends this event to itself, so you need to install a handler on the toolbar to receive this event. (Available in Mac OS X v10.2 and later.)

Available in Mac OS X v10.3 and later.

Declared in HIToolbar.h.

kEventToolbarItemRemoved

This event is sent when an item is removed from toolbar. It is called after the item has already been removed. The toolbar object sends this event to itself, so you need to install a handler on the toolbar to receive this event. (Available in Mac OS X v10.2 and later.)

Available in Mac OS X v10.3 and later.

Declared in HIToolbar.h.

kEventToolbarDisplayModeChanged

This event is sent when the display mode is changed for a toolbar. The toolbar object sends this event to itself, so you need to install a handler on the toolbar to receive this event. (Available in Mac OS X v10.2 and later.)

Available in Mac OS X v10.3 and later.

Declared in HIToolbar.h.

kEventToolbarDisplaySizeChanged

This event is sent when the display size is changed for a toolbar. The toolbar object sends this event to itself, so you need to install a handler on the toolbar to receive this event. (Available in Mac OS X v10.2 and later.)

Available in Mac OS X v10.3 and later.

Declared in HIToolbar.h.

kEventToolbarLayoutChanged

Sent when the layout of a toolbar changes (either an item has been moved, or the entire contents have been replaced). Basically it is sent for changes that would require a total resync with the current state of things. The toolbar object sends this event to itself, so you must install a handler on the toolbar to receive this event. (Available in Mac OS X v10.2 and later.)

Available in Mac OS X v10.3 and later.

Declared in HIToolbar.h.

kEventToolbarBeginMultiChange

This event is sent when multiple attributes are going to be changed at the same time. For example, the display mode and size can change at the same time. When this happens, instead of reacting twice (once for a display mode change and once for a display size change), you can listen to see if more than one attribute is about to change and wait to redraw the toolbar until you receive the kEventToolbarEndMultiChange event. The toolbar object sends this event to itself, so you need to install a handler on the toolbar to receive this event. (Available in Mac OS X v10.2 and later.)

Available in Mac OS X v10.3 and later.

Declared in HIToolbar.h.

kEventToolbarEndMultiChange

This event is sent when multiple changes in the toolbar have been made. For details, see the description of kEventToolbarBeginMultiChange. The toolbar object sends this event to itself, so you need to install a handler on the toolbar to receive this event. (Available in Mac OS X v10.2 and later.)

Available in Mac OS X v10.3 and later.

Declared in HIToolbar.h.

kEventToolbarGetSelectableIdentifiers

This event is sent to the delegate after the user clicks a toolbar item in order to get a list of all the items that can acquire a selection highlight when clicked. You are passed a mutable array to fill in with the identifiers. If you pass back a non-empty array and the clicked item’s identifier matches one of the identifiers that is in the list, the toolbar automatically draws that item with a selected highlight and removes highlighting from the previously selected item. Note that the selection only changes in the clicked window — it does not change in other windows that share the same toolbar. To share the selection across all windows that use the same toolbar, you need to manually change the kHIToolbarItemSelected attribute for the clicked item using HIToolbarItemChangeAttributes. In this case, you should not handle the kEventToolbarGetSelectableIdentifiers event. (Available in Mac OS X v10.4 and later.)

Available in Mac OS X v10.4 and later.

Declared in HIToolbar.h.

   kHIToolbarItemMutableAttrs = kHIToolbarItemCantBeRemoved |  kHIToolbarItemAnchoredLeft | kHIToolbarItemLabelDisabled |  kHIToolbarItemDisabled | kHIToolbarItemSelected
};

Constants

kHIToolbarItemNoAttributes

Pass this to indicate no attributes at all.

Available in Mac OS X v10.2 and later.

Declared in HIToolbar.h.

kHIToolbarItemAllowDuplicates

This indicates that an item can have more than one instance of itself in the toolbar. If this is not set, only one can be present. By default, the determining factor for what determines if two items are identical is the toolbar identifier.

Available in Mac OS X v10.2 and later.

Declared in HIToolbar.h.

kHIToolbarItemCantBeRemoved

This item can be rearranged, but it cannot be removed from the toolbar by the user.

Available in Mac OS X v10.2 and later.

Declared in HIToolbar.h.

kHIToolbarItemAnchoredLeft

This item cannot be moved at all by the user. It is anchored to the left of the toolbar. It is important that there not be any unanchored items to the left of this item, else dragging items around will be a bit wacky. You are responsible for making sure that anchored items are all on the left. This allows you to do toolbars like the one in the System Preferences app, where the first couple of items are stuck in place.

Available in Mac OS X v10.2 and later.

Declared in HIToolbar.h.

kHIToolbarItemIsSeparator

This indicates the item acts as a separator. This means two things at present. First, it means that it automatically shows up as a divider line in a menu representation of the toolbar, and second it means the view that represents this item can draw in the full top to bottom space that the toolbar item occupies in the toolbar.

Available in Mac OS X v10.2 and later.

Declared in HIToolbar.h.

kHIToolbarItemSendCmdToUserFocus

If this attribute bit is set, the command that gets sent out will be directed at the user focus instead of at the window the toolbar is attached to.

Available in Mac OS X v10.2 and later.

Declared in HIToolbar.h.

kHIToolbarItemLabelDisabled

If this attribute bit is set, clicking on the label of an item does nothing. This attribute is only considered when a custom view is present. When set, this attribute makes the toolbar item view unresponsive to clicks while still allowing clicks to be sent to the custom view. When the toolbar is in text-only mode and this attribute is set, the label is displayed in a disabled (grayed) appearance. You might want to change this attribute when switching between display modes. For example, the view switcher in the Finder does not respond to clicks on the label when in icon and text mode, but it does respond to clicks when in text-only mode. To change this behavior on the fly, listen for kEventToolbarItemViewConfigForMode in your custom view and adjust this attribute as you want. (Available in Mac OS X 10.3 and later.)

Available in Mac OS X v10.3 and later.

Declared in HIToolbar.h.

kHIToolbarItemDisabled

If this attribute bit is set, the item is disabled. Setting this attribute is the same as calling HIToolbarItemSetEnabled on the item with the inEnabled parameter set to false. (Available in Mac OS X v10.4 and later.)

Available in Mac OS X v10.4 and later.

Declared in HIToolbar.h.

kHIToolbarItemSelected

If this attribute bit is set, the item is drawn with a selected appearance. (Available in Mac OS X v10.4 and later.)

Available in Mac OS X v10.4 and later.

Declared in HIToolbar.h.

kHIToolbarItemValidAttrs

The set of all valid toolbar item attributes.

Available in Mac OS X v10.2 and later.

Declared in HIToolbar.h.

kHIToolbarItemMutableAttrs

The set of toolbar item attributes that can be changed by HIToolbarItemChangeAttributes and HIToolbarItemChangeAttributesInWindow. Any other attribute must be specified when it is created.

Available in Mac OS X v10.2 and later.

Declared in HIToolbar.h.

Available in Mac OS X v10.2 and later.

Declared in HIToolbar.h.

kEventToolbarItemGetPersistentData

This event is sent to the item when the toolbar is going to write out the configuration information for the item. Any custom items can listen for this event and add any extra information to what is written out into the config so that it can be reanimated later on from the same config data. Typically, you do not need to handle this event. (Available in Mac OS X v10.2 and later.)

Available in Mac OS X v10.2 and later.

Declared in HIToolbar.h.

kEventToolbarItemCreateCustomView

This event is sent to the toolbar item when it is time to create a view for it to display its contents. Implementors of custom toolbar items can install a handler for this event to create their own custom views for their items. (Available in Mac OS X v10.2 and later.)

Available in Mac OS X v10.2 and later.

kEventToolbarItemAcceptDrop

This event is sent when a drag enters a toolbar item. If the toolbar item wants to accept drags, it should respond to this event and return true in the kEventParamResult parameter. The toolbar item will be highlighted appropriately. If you are using a custom view, you do not need to respond to this event because the view system provides full drag and drop capability in order to support custom items that use the standard view. (Available in Mac OS X v10.3 and later.)

Available in Mac OS X v10.3 and later.

Declared in HIToolbar.h.

kEventToolbarItemSelectedStateChanged

This event is sent to the item itself when the selected state changes. Any interested parties can install handlers on the toolbar item to receive notifications. (Available in Mac OS X v10.4 and later.)

   kEventToolbarItemViewConfigForSize = 4,
   kEventToolbarItemViewEnterConfigMode = 5,
   kEventToolbarItemViewExitConfigMode = 6
};

Constants

kEventToolbarItemViewConfigForMode

This event notifies a toolbar item view that the toolbar’s display mode has changed. A custom toolbar item view can respond in any way it sees fit. Usually, responding to this is not necessary; for example, when the toolbar goes from icon to text only the view is automatically hidden, so there is not much to do. This event is for informational purposes only. (Available in Mac OS X v10.3 and later.)

Available in Mac OS X v10.3 and later.

Declared in HIToolbar.h.

kEventToolbarItemViewConfigForSize

This event notifies a toolbar item view that the toolbar’s display size has changed. A custom toolbar item view can respond to this in any way it sees fit. Usually, responding to this is not necessary. Some custom views might need to flush metrics caches when the display size changes. (Available in Mac OS X v10.3 and later.)

Available in Mac OS X v10.3 and later.

Declared in HIToolbar.h.

kEventToolbarItemViewEnterConfigMode

This event notifies a toolbar item view that configure mode has been entered. A custom toolbar item view can respond to this in any way it sees fit. For example, the space and flexible space mark themselves to draw a rectangle and merely invalidate so they get redrawn so they can be seen during configuration. (Available in Mac OS X v10.3 and later.)

Available in Mac OS X v10.3 and later.

Declared in HIToolbar.h.
