3{\bf Note:} constraints are now deprecated and you should use \helpref{sizers}{sizeroverview} instead.

5Objects of this class can be associated with a window to define its
6layout constraints, with respect to siblings or its parent.
7
8The class consists of the following eight constraints of class wxIndividualLayoutConstraint,
9some or all of which should be accessed directly to set the appropriate
10constraints.
11
12\begin{itemize}\itemsep=0pt
13\item {\bf left:} represents the left hand edge of the window
14\item {\bf right:} represents the right hand edge of the window
15\item {\bf top:} represents the top edge of the window
16\item {\bf bottom:} represents the bottom edge of the window
17\item {\bf width:} represents the width of the window
18\item {\bf height:} represents the height of the window
19\item {\bf centreX:} represents the horizontal centre point of the window
20\item {\bf centreY:} represents the vertical centre point of the window
21\end{itemize}
22
23Most constraints are initially set to have the relationship wxUnconstrained,
24which means that their values should be calculated by looking at known constraints.
25The exceptions are {\it width} and {\it height}, which are set to wxAsIs to
26ensure that if the user does not specify a constraint, the existing
27width and height will be used, to be compatible with panel items which often
28have take a default size. If the constraint is wxAsIs, the dimension will
29not be changed.

31\perlnote{In wxPerl the constraints are accessed as
32\begin{verbatim}
33  constraint = Wx::LayoutConstraints->new();
34  constraint->centreX->AsIs();
35  constraint->centreY->Unconstrained();
