	@description:
		The hbox class widget provides horizontal geometry management for its child widgets.
	@functions:
		!fn: $setSpacing(<spacing:uint>)
		Sets the default spacing of the widgets in pixels
		!fn: $setMargin(<margin:uint>)
		Sets the dimension of the layout margin : the distance from the border to the outermost child widget edges.
		!fn: $setStretchFactor(<widget:hobject>,<stretch:uint>)
		Sets the stretch factor of widget to stretch.
		!fn: $addStretch(<stretch:integer>)
		Adds a stretchable space with zero minimum size and stretch factor stretch to the end of this box layout.
		!fn: $setAlignment(<flag1:string>, <flag2:string>, ...)
		Sets the alignment for widget w to  flags, given as parameters.
		Valid flags are:Right,Left,Top,Bottom,HCenter,VCenter,Center
