189 <h2>LayoutAnchors</h2>
190 A class that implements Delphi's Anchors with wxLayoutConstraints.
191 <p>
192 Anchored sides maintain the distance from the edge of the
193 control to the same edge of the parent.
194 When neither side is selected, the control keeps the same
195 relative position to both sides.
196 <p>
197 The current position and size of the control and it's parent
198 is used when setting up the constraints. To change the size or
199 position of an already anchored control, set the constraints to
200 None, reposition or resize and reapply the anchors.
201 <p>
202 Examples:
203 <p>
204 Let's anchor the right and bottom edge of a control and
205 resize it's parent.
206 <p>
207 <pre>
208 ctrl.SetConstraints(LayoutAnchors(ctrl, left=0, top=0, right=1, bottom=1))

214 +---------+ | | * |
215 | +--*--+ |
216 +-------------------+
217 * = anchored edge
218 </pre>
219 <p>
220 When anchored on both sides the control will stretch horizontally.

223 ctrl.SetConstraints(LayoutAnchors(ctrl, 1, 0, 1, 1))
