+    @class wxWindowUpdateLocker
+    @wxheader{wupdlock.h}
+
+    This tiny class prevents redrawing of a wxWindow during its
+    lifetime by using wxWindow::Freeze and
+    wxWindow::Thaw methods. It is typically used for creating
+    automatic objects to temporarily suppress window updates before a batch of
+    operations is performed:
+
+    @code
+    void MyFrame::Foo()
+        {
+            m_text = new wxTextCtrl(this, ...);
+
+            wxWindowUpdateLocker noUpdates(m_text);
+            m_text-AppendText();
+            ... many other operations with m_text...
+            m_text-WriteText();
+        }
+    @endcode
+
+    Using this class is easier and safer than calling
+    wxWindow::Freeze and wxWindow::Thaw because you
+    don't risk to forget calling the latter.
