+  \class TQSize
+  \brief The TQSize class defines the size of a two-dimensional object.
+
+  \ingroup images
+  \ingroup graphics
+
+  A size is specified by a width and a height.
+
+  The coordinate type is TQCOORD (defined in \c <qwindowdefs.h> as \c int).
+  The minimum value of TQCOORD is TQCOORD_MIN (-2147483648) and the maximum
+  value is TQCOORD_MAX (2147483647).
+
+  The size can be set in the constructor and changed with setWidth()
+  and setHeight(), or using operator+=(), operator-=(), operator*=()
+  and operator/=(), etc. You can swap the width and height with
+  transpose(). You can get a size which holds the maximum height and
+  width of two sizes using expandedTo(), and the minimum height and
+  width of two sizes using boundedTo().
