+
+    \inmodule QtDesigner
+
+    QAbstractExtensionFactory is not intended to be instantiated
+    directly; use the QExtensionFactory instead.
+
+    In \QD, extension factories are used to look up and create named
+    extensions as they are required. For that reason, when
+    implementing a custom extension, you must also create a
+    QExtensionFactory, i.e a class that is able to make an instance of
+    your extension, and register it using \QD's \l
+    {QExtensionManager}{extension manager}.
+
+    When an extension is required, \QD's \l
+    {QExtensionManager}{extension manager} will run through all its
+    registered factories calling QExtensionFactory::createExtension()
+    for each until the first one that is able to create the requested
+    extension for the selected object, is found. This factory will
+    then make an instance of the extension.
