| 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. |
