	@doc:	tabwidget
	@keyterms:
		tabwidget object class,
	@title:
		tabwidget class
	@type:
		class
	@short:
		Provides a Tab Widget.
	@inherits:
		[class]object[/class]
		[class]widget[/class]
	@description:
		The tabwidget class provides a stack of tabbed widgets.[br]
		Each tab is associated with a different widget (called a `page').[br]
		Only the current tab's page is shown in the page area; all the others tabs pages are hidden.[br]
		The user can show a different page by clicking on its tab.[br]
	@functions:
		!fn: $addTab(<widget:object>,<text_label:string>,[<icon_id>])
		Adds another page to the tab view with the text label and optional icon.
		!fn: $insertTab(<widget:object>,<tex_label:string>,<index:uinteger>)
		Inserts another tab and page to the tab view with name and label-text specified.[br]
		If index is not specified, the tab is simply appended.[br]
		Otherwise the new tab is inserted at the specified position.
		!fn: $setTabToolTip(<tab_widget:object>,<tooltip:string>)
		Sets the tab tool tip for the tabwidget to <tooltip>.
		!fn: $removeTabToolTip(<tab_widget:object>)
		Removes the tab tool tip for the tab. If the page does not have a tip, nothing happens.
		!fn: $setTabLabel(<tab_widget>, <label:string>)
		Sets the tab label for <tab_widget>  to label.
		!fn: $changeTab(<tab_widget:object>,<label:text>,[<icon_id>])
		Defines a new label, and optional icon, for the tab .
		!fn: $setCurrentPage(<index:uinteger>)
		Sets the index position of the current tab page to <index>.
		!fn: <integer> $currentPageIndex()
		Returns the current page index.
		!fn: <string> $label(<index:uinteger>)
		Retunrs the label to the <index>.
		!fn: <string> $currentTabLabel()
		Returns the label of the current tab.
		!fn: $setMargin(<margin:integer>)
		Sets the margin in this tab widget to <margin>.
		!fn: <integer> $margin()
		Returns the margin in this tab widget.
		!fn: $removePage(<tab_widget:object>)
		Remove the page <tab_widget>. 
		!fn: $setTabPosition(<tab_position:string>)
		Sets TabPosition. Valid parameters are : Top, Bottom.
		!fn: <integer> $count()
		This property holds the number of tabs in the tab bar.
		!fn: $currentChangedEvent()
		This function is invoched when the current tab was changed.[br]
		The default implementation emits the [classfnc]$currentChange[/classfnc]() signal.
	@examples:
		[example]
			# First we'll create the main tabwidget.
			%Tabwidget=$new(tabwidget)
			%Tabwidget->$setToolTip("Example of TabWidget class")
			%Tabwidget->$setMargin(30)
			%Tabwidget->$setTabPosition(Top)
			
			# Now we'll create the new widgets and put they in to the main tabwidget.
			%firsttab=$new(widget,%Tabwidget)
			%secondtab=$new(widget,%Tabwidget)
			
			# Now we'll create the item to put in to tab's pages.
			%layoutfirsttab=$new(layout,%firsttab)
			%labelbt=$new(label,%firsttab)
			%labelbt->$settext(Botton Tab)
			%labeltt=$new(label,%firsttab)
			%labeltt->$settext(Top Tab)
			%buttontb=$new(button,%firsttab)
			%buttontb->$settext("To &Botton")
			%buttontt=$new(button,%firsttab)
			%buttontt->$settext("To &Top")
			
			# Now we'll give a layout to all items.
			# This also allows to use privateimpl without making buttons global variables
			%layoutfirsttab->$addwidget(%labelbt,0,0)
			%layoutfirsttab->$addwidget(%labeltt,0,1)
			%layoutfirsttab->$addwidget(%buttontb,1,0)
			%layoutfirsttab->$addwidget(%buttontt,1,1)
			
			# Add the page to the main tab.
			%Tabwidget->$addTab(%firsttab,Top&Button,33)
			
			# Implementing the action to do when the user click the buttons.
			privateimpl(%buttontb,mousepressevent)
			{
				%Tabwidget->$setTabPosition(Bottom)
			}
			privateimpl(%buttontt,mousepressevent)
			{
				%Tabwidget->$setTabPosition(Top)
			}
			
			# We do the same work  with the second tab's page.
			%layoutsecondtab=$new(layout,%secondtab)
			%labelwp=$new(label,%secondtab)
			%labelwp->$settext("Enjoy the new Class provided by")
			%layoutsecondtab->$addwidget(%labelwp,0,0)
			%labelwp->$setalignment("Center")
			%labelgen=$new(label,%secondtab)
			%labelgen->$settext(Grifisx \& Noldor)
			%labelgen->$setalignment("Center")
			%layoutsecondtab->$addwidget(%labelgen,1,0)
			%Tabwidget->$addTab(%secondtab,&About,50)
			
			# Let's show our example. 
			%Tabwidget->$show()
		[/example]
	@signals:
		!sg: $currentChange()
		This signal is emitted by the default implementation of [classfnc]$currentChangedEvent[/classfnc]().[br]
		If you reimplement that function you will have to emit the signal manually (if you still need it).[br]
