+/*!
+    \class TQPoint qpoint.h
+    \brief The TQPoint class defines a point in the plane.
+
+    \ingroup images
+    \ingroup graphics
+    \mainclass
+
+    A point is specified by an x coordinate and a y coordinate.
+
+    The coordinate type is \c TQCOORD (a 32-bit integer). The minimum
+    value of \c TQCOORD is \c TQCOORD_MIN (-2147483648) and the maximum
+    value is  \c TQCOORD_MAX (2147483647).
+
+    The coordinates are accessed by the functions x() and y(); they
+    can be set by setX() and setY() or by the reference functions rx()
+    and ry().
+
+    Given a point \e p, the following statements are all equivalent:
+    \code
+	p.setX( p.x() + 1 );
+	p += TQPoint( 1, 0 );
+	p.rx()++;
+    \endcode
+
+    A TQPoint can also be used as a vector. Addition and subtraction
+    of TQPoints are defined as for vectors (each component is added
+    separately). You can divide or multiply a TQPoint by an \c int or a
+    \c double. The function manhattanLength() gives an inexpensive
+    approximation of the length of the TQPoint interpreted as a vector.
+
+    Example:
+    \code
+	//TQPoint oldPos is defined somewhere else
+	MyWidget::mouseMoveEvent( TQMouseEvent *e )
+	{
+	    TQPoint vector = e->pos() - oldPos;
+	    if ( vector.manhattanLength() > 3 )
+	    ... //mouse has moved more than 3 pixels since oldPos
+	}
+    \endcode
+
+    TQPoints can be compared for equality or inequality, and they can
+    be written to and read from a TQStream.
