spacing
defaults to 0 if nothing is passed in. The other
optional parameter,
layout
,tellstheSimpleMenuthedirectionin
which to organize the menu items. The options are horizontal and
vertical with the default being set to horizontal. Once inside the
SimpleMenu class constructor, we
ll make the values of the
spacing
and
layout
parameters available to the rest of the class by assigning
them to the private variables through the (almost) same names of
_layout
and
_spacing
. The next line calls the
setDefaultFormats
method, which we
'
'
llgettoinjustabit.Afterthatcall,Iusethe
forEach
method from the Array class to call the
createMenuItem
method with
each item of the
menuArray
. More on that a little further in as well.
public function SimpleMenu(menuArray:Array, spacing:Number
= 0, layout:String =
"
horizontal
"
){
_layout = layout;
_spacing = spacing;
setDefaultFormats();
menuArray.forEach(createMenuItem);
}
