+<html><body>
+Objects of this class can be associated with a window to define its
+layout constraints, with respect to siblings or its parent.
+
+<p>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.
+
+<p><ul>
+<li>left: represents the left hand edge of the window
+
+<li>right: represents the right hand edge of the window
+
+<li>top: represents the top edge of the window
+
+<li>bottom: represents the bottom edge of the window
+
+<li>width: represents the width of the window
+
+<li>height: represents the height of the window
+
+<li>centreX: represents the horizontal centre point of the window
+
+<li>centreY: represents the vertical centre point of the window
+</ul>
+<p>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.
