\section{\class{wxLayoutConstraints}}\label{wxlayoutconstraints}
|
|
|
|
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.
|
|
|
|
\begin{itemize}\itemsep=0pt
|
|
\item {\bf left:} represents the left hand edge of the window
|
|
\item {\bf right:} represents the right hand edge of the window
|
|
\item {\bf top:} represents the top edge of the window
|
|
\item {\bf bottom:} represents the bottom edge of the window
|
|
\item {\bf width:} represents the width of the window
|
|
\item {\bf height:} represents the height of the window
|
|
\item {\bf centreX:} represents the horizontal centre point of the window
|
|
\item {\bf centreY:} represents the vertical centre point of the window
|
|
\end{itemize}
|
|
|
|
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 {\it width} and {\it 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.
