+
+
+The TQCanvasPixmapArray class provides an array of TQCanvasPixmaps.
+
+<p>
+
+
+<p> This class is used by <a href="qcanvassprite.html">TQCanvasSprite</a> to hold an array of pixmaps.
+It is used to implement animated sprites, i.e. images that change
+over time, with each pixmap in the array holding one frame.
+<p> Depending on the constructor you use you can load multiple pixmaps
+into the array either from a directory (specifying a wildcard
+pattern for the files), or from a list of TQPixmaps. You can also
+read in a set of pixmaps after construction using <a href="#readPixmaps">readPixmaps</a>().
+<p> Individual pixmaps can be set with <a href="#setImage">setImage</a>() and retrieved with
+<a href="#image">image</a>(). The number of pixmaps in the array is returned by
+<a href="#count">count</a>().
+<p> TQCanvasSprite uses an image's mask for collision detection. You
+can change this by reading in a separate set of image masks using
+<a href="#readCollisionMasks">readCollisionMasks</a>().
+<p> <p>See also <a href="graphics.html">Graphics Classes</a> and <a href="images.html">Image Processing Classes</a>.
+
+<hr><h2>Member Function Documentation</h2>
+<h3 class=fn><a name="TQCanvasPixmapArray"></a>TQCanvasPixmapArray::TQCanvasPixmapArray ()
+</h3>
+Constructs an invalid array (i.e. <a href="#isValid">isValid</a>() will return FALSE).
+You must call <a href="#readPixmaps">readPixmaps</a>() before being able to use this
+TQCanvasPixmapArray.
+
+<h3 class=fn><a name="TQCanvasPixmapArray-2"></a>TQCanvasPixmapArray::TQCanvasPixmapArray ( const&nbsp;<a href="qstring.html">TQString</a>&nbsp;&amp;&nbsp;datafilenamepattern, int&nbsp;fc = 0 )
+</h3>
+Constructs a TQCanvasPixmapArray from files.
+<p> The <em>fc</em> parameter sets the number of frames to be loaded for
+this image.
+<p> If <em>fc</em> is not 0, <em>datafilenamepattern</em> should contain "%1",
+e.g. "foo%1.png". The actual filenames are formed by replacing the
+%1 with four-digit integers from 0 to (fc - 1), e.g. foo0000.png,
+foo0001.png, foo0002.png, etc.
+<p> If <em>fc</em> is 0, <em>datafilenamepattern</em> is asssumed to be a
+filename, and the image contained in this file will be loaded as
+the first (and only) frame.
+<p> If <em>datafilenamepattern</em> does not exist, is not readable, isn't
+an image, or some other error occurs, the array ends up empty and
+<a href="#isValid">isValid</a>() returns FALSE.
+
+<h3 class=fn><a name="TQCanvasPixmapArray-3"></a>TQCanvasPixmapArray::TQCanvasPixmapArray ( <a href="qptrlist.html">TQPtrList</a>&lt;TQPixmap&gt;&nbsp;list, <a href="qptrlist.html">TQPtrList</a>&lt;TQPoint&gt;&nbsp;hotspots )
+</h3>
+<b>This function is obsolete.</b> It is provided to keep old source working. We strongly advise against using it in new code.
+<p> Use <a href="#TQCanvasPixmapArray">TQCanvasPixmapArray::TQCanvasPixmapArray</a>( <a href="qvaluelist.html">TQValueList</a><TQPixmap>, <a href="qpointarray.html">TQPointArray</a> )
+instead.
+<p> Constructs a TQCanvasPixmapArray from the list of TQPixmaps <em>list</em>. The <em>hotspots</em> list has to be of the same size as <em>list</em>.
+
+<h3 class=fn><a name="TQCanvasPixmapArray-4"></a>TQCanvasPixmapArray::TQCanvasPixmapArray ( <a href="qvaluelist.html">TQValueList</a>&lt;TQPixmap&gt;&nbsp;list, <a href="qpointarray.html">TQPointArray</a>&nbsp;hotspots = TQPointArray ( ) )
+</h3>
+Constructs a TQCanvasPixmapArray from the list of TQPixmaps in the
+<em>list</em>. Each pixmap will get a hotspot according to the <em>hotspots</em> array. If no hotspots are specified, each one is set to
+be at position (0, 0).
+<p> If an error occurs, <a href="#isValid">isValid</a>() will return FALSE.
+
+<h3 class=fn><a name="~TQCanvasPixmapArray"></a>TQCanvasPixmapArray::~TQCanvasPixmapArray ()
+</h3>
+Destroys the pixmap array and all the pixmaps it contains.
+
+<h3 class=fn>uint <a name="count"></a>TQCanvasPixmapArray::count () const
+</h3>
+
+<p> Returns the number of pixmaps in the array.
+
+<h3 class=fn><a href="qcanvaspixmap.html">TQCanvasPixmap</a>&nbsp;* <a name="image"></a>TQCanvasPixmapArray::image ( int&nbsp;i ) const
+</h3>
+
+<p> Returns pixmap <em>i</em> in the array, if <em>i</em> is non-negative and less
+than than <a href="#count">count</a>(), and returns an unspecified value otherwise.
+
+<h3 class=fn>bool <a name="isValid"></a>TQCanvasPixmapArray::isValid () const
+</h3>
+Returns TRUE if the pixmap array is valid; otherwise returns
+FALSE.
+
+<h3 class=fn>bool <a name="operator!"></a>TQCanvasPixmapArray::operator! ()
+</h3>
+<b>This function is obsolete.</b> It is provided to keep old source working. We strongly advise against using it in new code.
+<p> Use <a href="#isValid">isValid</a>() instead.
+<p> This returns FALSE if the array is valid, and TRUE if it is not.
+
+<h3 class=fn>bool <a name="readCollisionMasks"></a>TQCanvasPixmapArray::readCollisionMasks ( const&nbsp;<a href="qstring.html">TQString</a>&nbsp;&amp;&nbsp;filename )
+</h3>
+Reads new collision masks for the array.
+<p> By default, <a href="qcanvassprite.html">TQCanvasSprite</a> uses the image mask of a sprite to
+detect collisions. Use this function to set your own collision
+image masks.
+<p> If <a href="#count">count</a>() is 1 <em>filename</em> must specify a real filename to read
+the mask from. If count() is greater than 1, the <em>filename</em> must
+contain a "%1" that will get replaced by the number of the mask to
+be loaded, just like <a href="#readPixmaps">TQCanvasPixmapArray::readPixmaps</a>().
+<p> All collision masks must be 1-bit images or this function call
+will fail.
+<p> If the file isn't readable, contains the wrong number of images,
+or there is some other error, this function will return FALSE, and
+the array will be flagged as invalid; otherwise this function
+returns TRUE.
+<p> <p>See also <a href="#isValid">isValid</a>().
+
+<h3 class=fn>bool <a name="readPixmaps"></a>TQCanvasPixmapArray::readPixmaps ( const&nbsp;<a href="qstring.html">TQString</a>&nbsp;&amp;&nbsp;filenamepattern, int&nbsp;fc = 0 )
+</h3>
+Reads one or more pixmaps into the pixmap array.
+<p> If <em>fc</em> is not 0, <em>filenamepattern</em> should contain "%1", e.g.
+"foo%1.png". The actual filenames are formed by replacing the %1
+with four-digit integers from 0 to (fc - 1), e.g. foo0000.png,
+foo0001.png, foo0002.png, etc.
+<p> If <em>fc</em> is 0, <em>filenamepattern</em> is asssumed to be a filename,
+and the image contained in this file will be loaded as the first
+(and only) frame.
+<p> If <em>filenamepattern</em> does not exist, is not readable, isn't an
+image, or some other error occurs, this function will return
+FALSE, and <a href="#isValid">isValid</a>() will return FALSE; otherwise this function
+will return TRUE.
+<p> <p>See also <a href="#isValid">isValid</a>().
+
+<h3 class=fn>void <a name="setImage"></a>TQCanvasPixmapArray::setImage ( int&nbsp;i, <a href="qcanvaspixmap.html">TQCanvasPixmap</a>&nbsp;*&nbsp;p )
+</h3>
+Replaces the pixmap at index <em>i</em> with pixmap <em>p</em>.
+<p> The array takes ownership of <em>p</em> and will delete <em>p</em> when the
+array itself is deleted.
+<p> If <em>i</em> is beyond the end of the array the array is extended to at
+least i+1 elements, with elements <a href="#count">count</a>() to i-1 being initialized
+to 0.
