| | 107 | Objects of this class can be associated with a window to define its |
| | 108 | layout constraints, with respect to siblings or its parent. |
| | 109 | |
| | 110 | <p>The class consists of the following eight constraints of class |
| | 111 | wxIndividualLayoutConstraint, some or all of which should be accessed |
| | 112 | directly to set the appropriate constraints. |
| | 113 | |
| | 114 | <p><ul> |
| | 115 | <li>left: represents the left hand edge of the window |
| | 116 | |
| | 117 | <li>right: represents the right hand edge of the window |
| | 118 | |
| | 119 | <li>top: represents the top edge of the window |
| | 120 | |
| | 121 | <li>bottom: represents the bottom edge of the window |
| | 122 | |
| | 123 | <li>width: represents the width of the window |
| | 124 | |
| | 125 | <li>height: represents the height of the window |
| | 126 | |
| | 127 | <li>centreX: represents the horizontal centre point of the window |
| | 128 | |
| | 129 | <li>centreY: represents the vertical centre point of the window |
| | 130 | </ul> |
| | 131 | <p>Most constraints are initially set to have the relationship |
| | 132 | wxUnconstrained, which means that their values should be calculated by |
| | 133 | looking at known constraints. The exceptions are width and height, |
| | 134 | which are set to wxAsIs to ensure that if the user does not specify a |
| | 135 | constraint, the existing width and height will be used, to be |
| | 136 | compatible with panel items which often have take a default size. If |
| | 137 | the constraint is wxAsIs, the dimension will not be changed. |
