\section{\class{wxGauge}}\label{wxgauge}
A gauge is a horizontal or vertical bar which shows a quantity (often time).
+
+wxGauge supports two working modes: determinate and indeterminate progress.
+
+The first is the usual working mode (see \helpref{SetValue}{wxgaugesetvalue}
+and \helpref{SetRange}{wxgaugesetrange}) while the second can be used when
+the program is doing some processing but you don't know how much progress is
+being done.
+In this case, you can periodically call the \helpref{Pulse}{wxgaugepulse}
+function to make the progress bar switch to indeterminate mode (graphically
+it's usually a set of blocks which move or bounce in the bar control).
+
+wxGauge supports dynamic switch between these two work modes.
+
There are no user commands for the gauge.

-\wxheading{Remarks}
-
-Under Windows 95, there are two different styles of gauge: normal gauge, and progress bar (when
-the {\bf wxGA\_PROGRESSBAR} style is used). A progress bar is always horizontal.

\membersection{wxGauge::SetValue}\label{wxgaugesetvalue}
\func{void}{SetValue}{\param{int }{pos}}
-Sets the position of the gauge.
+Sets the position of the gauge. The \arg{pos} must be between $0$ and the gauge
+range as returned by \helpref{GetRange}{wxgaugegetrange}, inclusive.
+
+This function makes the gauge switch to determinate mode, if it was in
+indeterminate mode before.
\wxheading{Parameters}
\helpref{wxGauge::GetValue}{wxgaugegetvalue}
+\membersection{wxGauge::Pulse}\label{wxgaugepulse}
+
+\func{void}{Pulse}{\void}
+
+Switch the gauge to indeterminate mode (if required) and makes the gauge move
+a bit to indicate the user that some progress has been made.
+
+Note that after calling this function the value returned by \helpref{GetValue}{wxgaugegetvalue}
+is undefined and thus you need to explicitely call \helpref{SetValue}{wxgaugesetvalue} if you
+want to restore the determinate mode.
