 \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.
