wxLayoutConstraints

Note: constraints are now deprecated and you should use sizers instead.
Objects of this class can be associated with a window to define its layout constraints, with respect to siblings or its parent.
The class consists of the following eight constraints of class wxIndividualLayoutConstraint, some or all of which should be accessed directly to set the appropriate constraints.
Most constraints are initially set to have the relationship 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.
wxPerl note: In wxPerl the constraints are accessed as
  constraint = Wx::LayoutConstraints->new();
  constraint->centreX->AsIs();
  constraint->centreY->Unconstrained();
