118 Objects of this class can be associated with a window to define its
119 layout constraints, with respect to siblings or its parent.
120
121 The class consists of the following eight constraints of class
122 wxIndividualLayoutConstraint, some or all of which should be accessed
123 directly to set the appropriate constraints.
124
125 left: represents the left hand edge of the window
126
127 right: represents the right hand edge of the window
128
129 top: represents the top edge of the window
130
131 bottom: represents the bottom edge of the window
132
133 width: represents the width of the window
134
135 height: represents the height of the window
136
137 centreX: represents the horizontal centre point of the window
138
139 centreY: represents the vertical centre point of the window
140
141 Most constraints are initially set to have the relationship
142 wxUnconstrained, which means that their values should be calculated by
143 looking at known constraints. The exceptions are width and height,
144 which are set to wxAsIs to ensure that if the user does not specify a
145 constraint, the existing width and height will be used, to be
146 compatible with panel items which often have take a default size. If
147 the constraint is wxAsIs, the dimension will not be changed.
