This element is used to construct a step-by-step wizard found in some applications to guide users through a task. It is used for a window with several steps contained on several pages. This element provides the header and buttons along the bottom, and also handles navigation between the pages. Each page should be constructed using a wizardpage . The pages are displayed in the order that they are placed in the wizard, unless you use the next and pageid attributes on the pages to change the sequence. The wizard will rendered in a manner suitable for the user's selected theme and platform. In newer versions of Mozilla, a statusbar may be placed directly inside the wizard element which will be shared among all pages.

More information is available in the XUL tutorial.

activetitlebarcolor New in Firefox 3: Type: color string; Specify background color of the window's titlebar when it is active (foreground). Moreover this hides separator between titlebar and window contents. This only affects Mac OS X.

firstpage: Type: boolean; true if the wizard is on the first page.

onextra1: Type: script code; This should be set to code which is called when the user presses the extra1 button.

onextra2: Type: script code; This should be set to code which is called when the user presses the extra2 button.

onwizardback: Type: script code; This should be set to code which is called when the user presses the Back button. Return true to allow the previous page to be displayed and false to disallow moving back a page. Use the canRewind property to indicate to the user (by disabling the Back button) that they cannot go back a page.

onwizardcancel: Type: script code; This should be set to code which is called when the user presses the Cancel button. Return true to allow the wizard to be cancelled, and close the wizard, or return false to prevent the wizard from being cancelled.

canAdvance: Type: boolean; This property is set to true if the user can press the Next button to go to the next page. If this property is false, the user cannot navigate to the next page. Set this property to true to indicate that the user can go to the next page. Set to false to disallow moving to the next page. This has the effect of enabling or disabling the Next button, or, on the last page of the wizard, the Finish button.

canRewind: Type: boolean; This property is set to true if the user can press the Back button to go to the previous page. If this property is false, the user cannot navigate to the previous page. Set this property to true to indicate that the user can go back a page. Set to false to disallow moving to the previous page. This has the effect of enabling or disabling the Back button.

currentPage: Type: wizardpage element; This property returns the wizardpage element that is currently displayed. You can modify this value to change the current page.

onFirstPage: Type: boolean; This property is set to true if the user is on the first page, which may or may not be the first index.

onLastPage: Type: boolean; This property is set to true if the user is on the last page of the wizard.

pageCount: Type: integer; This property holds the number of pages in the wizard .

pageIndex: Type: integer; This property returns the index of the currently selected page. You can change the selected page by modifying this property.

pageStep: Type: integer; This property returns the number of pages that the user has navigated through so far, meaning that the user would press the Back button this many times to go back to the beginning. This property is different than pageIndex , because pages are not necessarily navigated in order.

title: Type: string; The title that appears at the top of the wizard . This is overridden by the label attribute on the individual pages.

wizardPages: Type: DOM NodeList of wizardpage elements; This property holds the list of wizardpage elements in the wizard .
