	@description:
		A wizard is an input dialog that consists of a sequence of dialog pages. It walks the user through a process step by step.[br]
	@functions:
	!fn: $addPage(<page_widget:object>,<title:string>)
	Add a page with title.<page_widget> must be a widget's object.

	If enable is set to 1, page page has a [i]back[/i] button; otherwise page has no [i]back[/i] button.[br]
	By default all pages have this button.
	!fn: $setNextEnabled(<page_widget>,<bEnabled:boolean>)
	If enable is set to 1, page page has a [i]next[/i] button; otherwise the [i]next[/i] button on page is disabled.[br]
	By default all pages have this button.
	!fn: $setFinishEnabled(<page_widget>,<bEnabled:boolean>)
	If enable is set to 1, page page has a [i]finish[/i] button; otherwise the [i]finish[/i] button on page is disabled.[br]
	By default NO pages have this button.
	!fn: $setHelpEnabled(<page_widget>,<bEnabled:boolean>)
	If enable is set to 1, page page has a Help button; otherwise the [i]help[/i] button on page is disabled.[br]
	By default all pages have this button.
	!fn: $setNextBtnText(<text:string>)
	Set the text for button [i]next[/i].
	!fn: $setBackBtnText(<text:string>)
	Set the text for button [i]back[/i].
	!fn: $setFinishBtnText(<text:string>)
	Set the text for button [i]finish[/i].
	!fn: $setHelpBtnText(<text:string>)
	Set the text for button Help.
	!fn: $acceptEvent()
	This function is called when the user clicks on the [i]finish[/i] button.
	!fn: $rejectEvent()
	This function is called when the user clicks on the [i]reject[/i] button.
	!fn: $nextClickedEvent()
	This function is called when the user clicks on the [i]next[/i] button.
	!fn: $backClickedEvent()
	This function is called when the user clicks on the [i]back[/i] button.
	@signals:
	!sg: $nextClicked()
	This signal is emitted by the default implementation of [classfnc]$nextClickedEvent[/classfnc]().
	!sg: $backClicked()
	This signal is emitted by the default implementation of [classfnc]$backClickedEvent[/classfnc]().
