| 118 | Objects of this class can be associated with a window to define its | |
| 119 | layout constraints, with respect to siblings or its parent. | |
| cf694132 | 120 | |
| 1fded56b RD |
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. | |
| cf694132 RD |
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 | ||
| 1fded56b RD |
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. | |
