wxUnconstrained, which means that their values should be calculated by

looking at known constraints. The exceptions are width and height,
|
|

|
|
which are set to wxAsIs to ensure that if the user does not specify a

|
|

constraint, the existing width and height will be used, to be

compatible with panel items which often have take a default size. If

the constraint is wxAsIs, the dimension will not be changed.
