<hr><h2><a name="details"></a>Detailed Description</h2>
An array of <a href="qcanvaspixmap.html">QCanvasPixmap</a> to have multiple frames for animation.
<p>
This allows sprite objects
to have multiple frames for animation.
<p>QCanvasPixmaps for sprite objects are collected into
QCanvasPixmapArrays, which are
the set of images a sprite will use, indexed by the sprite's
frame. This allows sprites to simply have animated forms.
<hr><h2>Member Function Documentation</h2>
<h3 class="fn"><a name="28edf0"></a>QCanvasPixmapArray::QCanvasPixmapArray()</h3>
<p>Constructs a null array. You should call <a href="#6493ec">readPixmaps</a>() before using it
further.
<h3 class="fn"><a name="9ddfa3"></a>QCanvasPixmapArray::QCanvasPixmapArray(<a href="qlist.html">QList</a><<a href="qpixmap.html">QPixmap</a>>list, <a href="qlist.html">QList</a><<a href="qpoint.html">QPoint</a>>hotspots)</h3>
<p>Constructs a QCanvasPixmapArray from QPixmaps.
<h3 class="fn"><a name="1e69bc"></a>QCanvasPixmapArray::QCanvasPixmapArray(const<a href="qstring.html">QString</a>&datafilenamepattern, intfc=0)</h3>
<p>Constructs a QCanvasPixmapArray from files. See <a href="#6493ec">readPixmaps</a>() for details.
<h3 class="fn"><a name="915b97"></a>QCanvasPixmapArray::~QCanvasPixmapArray()</h3>
<p>Destructs the pixmap array.
<h3 class="fn">uint<a name="beaaa2"></a>QCanvasPixmapArray::count()const</h3>
<p>Returns the length of the array.
<h3 class="fn"><a href="qcanvaspixmap.html">QCanvasPixmap</a>*<a name="ccfeda"></a>QCanvasPixmapArray::image(inti)const</h3>
<p>Returns the <em>i-th</em> pixmap in the array.
<h3 class="fn">int<a name="04e6bd"></a>QCanvasPixmapArray::operator!()</h3>
<p>Constructor failure check.
<h3 class="fn">bool<a name="cb792b"></a>QCanvasPixmapArray::readCollisionMasks(const<a href="qstring.html">QString</a>&fname)</h3>
<p>When testing sprite collision detection
the default is to use the image mask of the sprite. By using
readCollisionMasks(), an alternate mask can be used. The images
must be 1-bit deep.
<h3 class="fn">bool<a name="6493ec"></a>QCanvasPixmapArray::readPixmaps(const<a href="qstring.html">QString</a>&datafilenamepattern, intfc=0)</h3>
<p>Sets the array to <em>fc</em> pixmaps, read from files.
<p>If <em>fc</em> is not 0, the
filenames should contain a "%1",
strings such as "foo%1.png". The actual
filenames are formed by replacing the %1 with each integer
from 0 to fc-1, with leading zeroes sufficient for 4 digits.
eg. foo0000.png, foo0001.png, foo0002.png, etc.
<h3 class="fn">void<a name="c9c0d1"></a>QCanvasPixmapArray::setImage(inti, <a href="qcanvaspixmap.html">QCanvasPixmap</a>*p)</h3>
<p>Replaces the <em>i-th</em> pixmap by <em>p.</em> Note that <em>p</em>
becomes owned by the array - it will be deleted later.
<p>If <em>i</em> is more than <a href="#beaaa2">count</a>()-1, the array is extended to make room.
