 \section{\class{wxSize}}\label{wxsize}
 
 A {\bf wxSize} is a useful data structure for graphics operations.
 It simply contains integer {\it width} and {\it height} members.
 
-wxSize is used throughout wxWindows as well as wxPoint which, although almost
+wxSize is used throughout wxWidgets as well as wxPoint which, although almost
 equivalent to wxSize, has a different meaning: wxPoint represents a position
 while wxSize - the size.
