<hr><h2><a name="details"></a>Detailed Description</h2>
The QRect class defines a rectangle in the plane.
<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 QCOORD (defined in <a href="qwindowdefs-h.html">qwindowdefs.h</a> as <code>int).</code>
The minimum value of QCOORD is QCOORD_MIN (-2147483648) and the maximum
value is QCOORD_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, then 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, where 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 downwards and the
positive x axis is from the left to the right.

<h3 class="fn">bool<a name="535b61"></a>QRect::contains(constQRect&r, boolproper=FALSE)const</h3>
<p>Returns TRUE if the rectangle <em>r</em> is inside this rectangle.
<p>If <em>proper</em> is TRUE, this function returns TRUE only if <em>r</em> is
entirely inside (not on the edge).
<p>See also <a href="#81e8a3">unite</a>(), <a href="#4fc24a">intersect</a>() and <a href="#5b3d2b">intersects</a>().
