tabs

A row of tabs. A tabs element should be placed inside a tabbox and should contain tab elements.

NB: You can add some other elements to tabs such as button, but they will receive an index. Activating them will not change the selectedIndex.

More information is available in the XUL tutorial.

(example needed)

closebutton Obsolete since Gecko 1.9.2: Type: boolean; If this attribute is set to true, the tabs row will have a "new tab" button and "close" button on the ends. This feature is used by the tabbrowser to provide the facilities for adding and closing tabs. You can set an image to the "new tab" and "close" buttons by applying them to the tabs-newbutton and tabs-closebutton classes respectively.

disableclose: Type: boolean; If this attribute is true the close button will be disabled.

disabled: Type: boolean; Indicates whether the element is disabled or not. If this attribute is set, the element is disabled. Disabled elements are usually drawn with grayed-out text. If the element is disabled, it does not respond to user actions, it cannot be focused, and the command event will not fire. In the case of form elements, it will not be submitted. Do not set the attribute to true, as this will suggest you can set it to false to enable the element again, which is not the case.
The disabled attribute is allowed only for form controls. Using it with an anchor tag (an <a> link) will have no effect.

The element will, however, still respond to mouse events. To enable the element, leave this attribute out entirely.; Visible controls have a disabled property which, except for menus and menuitems, is normally preferred to use of the attribute, as it may need to update additional state.

onclosetab: Type: script code; This script will be called when the close tab button is clicked.

onnewtab: Not in Firefox; Type: script code; This script will be called when the new tab button is clicked.

onselect: Type: script code; This event is sent to the tabs element when this tab is changed.

selectedIndex: Type: integer; Gets and sets the index of the currently selected panel. The first item is at index 0.

setfocus: Type: boolean; If true or omitted, the focus will be given to the first element in the corresponding tabpanel when the tabs are navigated via the keyboard. If this attribute is false, the focus does not change during navigation.

tabindex: Type: integer; The tab order of the element. The tab order is the order in which the focus is moved when the user presses the "tab" key. Elements with a higher tabindex are later in the tab sequence.

tooltiptextnew: Not in Firefox; Type: string; Used to set the text which appears in the tooltip when the user moves the mouse over the new button in the tab row.

accessibleType: Type: integer; A value indicating the type of accessibility object for the element.

disabled: Type: boolean; Gets and sets the value of the disabled attribute.

itemCount: Type: integer; Read only property holding the number of child items.

selectedIndex: Type: integer; Returns the index of the currently selected item. You may select an item by assigning its index to this property. By assigning -1 to this property, all items will be deselected. Returns -1 if no items are selected

selectedItem: Type: element; Holds the currently selected item. If no item is currently selected, this value will be null. You can select an item by setting this value. A select event will be sent to the controlling container (i.e. the listbox, richlistbox, radiogroup, etc., not the list item that was selected) when it is changed either via this property, the selectedIndex property, or changed by the user.

tabbox: Type: tabbox element; Returns the tabbox element that contains the tabs.

tabIndex: Type: integer; Gets and sets the value of the tabindex attribute.

value: Type: string; Gets and sets the value of the value attribute. For textbox and user editable menulist elements, the contents, as visible to the user, are read and set using the Textbox.value and Menulist.value syntax.

advanceSelectedTab( dir, wrap ): Return type: no return value; If the argument dir is set to 1, the currently selected tab changes to the next tab. If the argument dir is set to -1, the currently selected tab changes to the previous tab. If the wrap argument is true, the adjustment will wrap around when the first or last tab is reached.

appendItem( label, value ): Return type: element; Creates a new item and adds it to the end of the existing list of items. You may optionally set a value. The function returns the newly created element.

getIndexOfItem( item ): Return type: integer; Returns the zero-based position of the specified item. Items are numbered starting at the first item displayed in the list.

getItemAtIndex( index ): Return type: element; Returns the element that is at the specified index.

insertItemAt( index, label, value ): Return type: element; This method creates a new item and inserts it at the specified position. You may optionally set a value. The new item element is returned.

removeItemAt( index ): Return type: element; Removes the child item in the element at the specified index. The method returns the removed item.
