+/*! \class TextEditFindWidget
+
+    \brief A search bar that is commonly added below the searchable text.
+
+    \internal
+
+    This widget implements a search bar which becomes visible when the user
+    wants to start searching. It is a modern replacement for the commonly used
+    search dialog. It is usually placed below a QTextEdit using a QVBoxLayout.
+
+    The QTextEdit instance will need to be associated with this class using
+    setTextEdit().
+
+    The search is incremental and can be set to case sensitive or whole words
+    using buttons available on the search bar.
+
+    \sa QTextEdit
