	117	overview = """\
	118	Objects of this class can be associated with a window to define its layout constraints, with respect to siblings or its parent.
	119
	120	The class consists of the following eight constraints of class wxIndividualLayoutConstraint, some or all of which should be accessed directly to set the appropriate constraints.
	121
	122	left: represents the left hand edge of the window
	123
	124	right: represents the right hand edge of the window
	125
	126	top: represents the top edge of the window
	127
	128	bottom: represents the bottom edge of the window
	129
	130	width: represents the width of the window
	131
	132	height: represents the height of the window
	133
	134	centreX: represents the horizontal centre point of the window
	135
	136	centreY: represents the vertical centre point of the window
	137
	138	Most constraints are initially set to have the relationship wxUnconstrained, which means that their values should be calculated by looking at known constraints. The exceptions are width and height, which are set to wxAsIs to ensure that if the user does not specify a constraint, the existing width and height will be used, to be compatible with panel items which often have take a default size. If the constraint is wxAsIs, the dimension will not be changed.
