-    If two pixmaps are inserted into the cache using equal keys, then the
-    last pixmap will hide the first pixmap. The QHash and QCache classes do
-    exactly the same.
+    The cache associates a pixmap with a user-provided string as a key,
+    or with a QPixmapCache::Key that the cache generates.
+    Using QPixmapCache::Key for keys is faster than using strings. The string API is
+    very convenient for complex keys but the QPixmapCache::Key API will be very
+    efficient and convenient for a one-to-one object-to-pixmap mapping \mdash in
+    this case, you can store the keys as members of an object.
+
+    If two pixmaps are inserted into the cache using equal keys then the
+    last pixmap will replace the first pixmap in the cache. This follows the
+    behavior of the QHash and QCache classes.
 
     The cache becomes full when the total size of all pixmaps in the
     cache exceeds cacheLimit(). The initial cache limit is
-    2048 KB(2 MB) for Embedded, 10240 KB (10
-    MB) for Desktops; it is changed with setCacheLimit().
-    A pixmap takes roughly (\e{width} * \e{height} * \e{depth})/8 bytes of memory.
-
-    The \e{Qt Quarterly} article
-    \l{http://doc.trolltech.com/qq/qq12-qpixmapcache.html}{Optimizing
-    with QPixmapCache} explains how to use QPixmapCache to speed up
-    applications by caching the results of painting.
+    2048 KB (2 MB) on embedded platforms, 10240 KB (10 MB) on desktop
+    platforms; you can change this by calling setCacheLimit() with the
+    required value.
