-
-
-The TQRect class defines a rectangle in the plane.
-<p>
-
-
-<p> A rectangle is internally represented as an upper-left corner and
-a bottom-right corner, but it is normally expressed as an
-upper-left corner and a size.
-<p> The coordinate type is TQCOORD (defined in <a href="qwindowdefs-h.html">qwindowdefs.h</a> as <tt>int</tt>). The minimum value of TQCOORD is TQCOORD_MIN (-2147483648) and
-the maximum value is TQCOORD_MAX (2147483647).
-<p> Note that the size (width and height) of a rectangle might be
-different from what you are used to. If the top-left corner and
-the bottom-right corner are the same, the height and the width of
-the rectangle will both be 1.
-<p> Generally, <em>width = right - left + 1</em> and <em>height = bottom - top + 1</em>. We designed it this way to make it correspond to
-rectangular spaces used by drawing functions in which the width
-and height denote a number of pixels. For example, drawing a
-rectangle with width and height 1 draws a single pixel.
-<p> The default coordinate system has origin (0, 0) in the top-left
-corner. The positive direction of the y axis is down, and the
-positive x axis is from left to right.
-<p> A TQRect can be constructed with a set of left, top, width and
-height integers, from two TQPoints or from a <a href="qpoint.html">TQPoint</a> and a <a href="qsize.html">TQSize</a>.
-After creation the dimensions can be changed, e.g. with <a href="#setLeft">setLeft</a>(),
-<a href="#setRight">setRight</a>(), <a href="#setTop">setTop</a>() and <a href="#setBottom">setBottom</a>(), or by setting sizes, e.g.
-<a href="#setWidth">setWidth</a>(), <a href="#setHeight">setHeight</a>() and <a href="#setSize">setSize</a>(). The dimensions can also be
-changed with the move functions, e.g. <a href="#moveBy">moveBy</a>(), <a href="#moveCenter">moveCenter</a>(),
-<a href="#moveBottomRight">moveBottomRight</a>(), etc. You can also add coordinates to a
-rectangle with <a href="#addCoords">addCoords</a>().
-<p> You can test to see if a TQRect contains a specific point with
-<a href="#contains">contains</a>(). You can also test to see if two TQRects intersect with
-<a href="#intersects">intersects</a>() (see also <a href="#intersect">intersect</a>()). To get the bounding rectangle
-of two TQRects use <a href="#unite">unite</a>().
-<p> <p>See also <a href="qpoint.html">TQPoint</a>, <a href="qsize.html">TQSize</a>, <a href="graphics.html">Graphics Classes</a>, and <a href="images.html">Image Processing Classes</a>.
