   1 \section{\class{wxLayoutConstraints}}\label{wxlayoutconstraints}
   2
   3 Objects of this class can be associated with a window to define its
   4 layout constraints, with respect to siblings or its parent.
   5
   6 The class consists of the following eight constraints of class wxIndividualLayoutConstraint,
   7 some or all of which should be accessed directly to set the appropriate
   8 constraints.
   9
  10 \begin{itemize}\itemsep=0pt
  11 \item {\bf left:} represents the left hand edge of the window
  12 \item {\bf right:} represents the right hand edge of the window
  13 \item {\bf top:} represents the top edge of the window
  14 \item {\bf bottom:} represents the bottom edge of the window
  15 \item {\bf width:} represents the width of the window
  16 \item {\bf height:} represents the height of the window
  17 \item {\bf centreX:} represents the horizontal centre point of the window
  18 \item {\bf centreY:} represents the vertical centre point of the window
  19 \end{itemize}

  21 Most constraints are initially set to have the relationship wxUnconstrained,
  22 which means that their values should be calculated by looking at known constraints.
  23 The exceptions are {\it width} and {\it height}, which are set to wxAsIs to
  24 ensure that if the user does not specify a constraint, the existing
  25 width and height will be used, to be compatible with panel items which often
  26 have take a default size. If the constraint is wxAsIs, the dimension will
  27 not be changed.
