+\section{\class{wxLogNull}}\label{wxlognull}
+
+This class allows to temporarily suspend logging. All calls to the log
+functions during the life time of an object of this class are just ignored.
+
+In particular, it can be used to suppress the log messages given by wxWindows
+itself but it should be noted that it is rarely the best way to cope with this
+problem as {\bf all} log messages are suppressed, even if they indicate a
+completely different error than the one the programmer wanted to suppress.
+
+For instance, the example of the overview:
+
+{\small
+\begin{verbatim}
+  wxFile file;
+
+  // wxFile.Open() normally complains if file can't be opened, we don't want it
+  {
+    wxLogNull logNo;
+    if ( !file.Open("bar") )
+      ... process error ourselves ...
+  } // ~wxLogNull called, old log sink restored
+
+  wxLogMessage("..."); // ok
+\end{verbatim}
+}
+
+would be better written as:
+
+{\small
+\begin{verbatim}
+  wxFile file;
+
+  // don't try to open file if it doesn't exist, we are prepared to deal with
+  // this ourselves - but all other errors are not expected
+  if ( wxFile::Exists("bar") )
+  {
+      // gives an error message if the file couldn't be opened

+This class represents a background log window: to be precise, it collects all

+log target which was active at the moment of its creation. This allows, for
+example, to show all the log messages in a frame but still continue to process
+them normally by showing the standard log dialog.
