\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.

for further details.
\membersection{wxGauge::GetBezelFace}\label{wxgaugegetbezelface}

\membersection{wxGauge::GetShadowWidth}\label{wxgaugegetshadowwidth}
\constfunc{int}{GetShadowWidth}{\void}
Returns the 3D shadow margin width.
\wxheading{Remarks}
This method is not implemented (returns $0$) for most platforms.
\wxheading{See also}
\helpref{wxGauge::SetShadowWidth}{wxgaugesetshadowwidth}
\membersection{wxGauge::GetValue}\label{wxgaugegetvalue}
\constfunc{int}{GetValue}{\void}
Returns the current position of the gauge.
\wxheading{See also}
\helpref{wxGauge::SetValue}{wxgaugesetvalue}
\membersection{wxGauge::IsVertical}\label{wxgaugeisvertical}
\constfunc{bool}{IsVertical}{\void}
Returns \true if the gauge is vertical (has \texttt{wxGA\_VERTICAL} style) and
\false otherwise.
\membersection{wxGauge::SetBezelFace}\label{wxgaugesetbezelface}
\func{void}{SetBezelFace}{\param{int }{width}}
Sets the 3D bezel face width.
\wxheading{Remarks}
This method is not implemented (doesn't do anything) for most platforms.
\wxheading{See also}
\helpref{wxGauge::GetBezelFace}{wxgaugegetbezelface}
\membersection{wxGauge::SetRange}\label{wxgaugesetrange}
\func{void}{SetRange}{\param{int }{range}}
Sets the range (maximum value) of the gauge.
This function makes the gauge switch to determinate mode, if it's not already.
\wxheading{See also}
\helpref{wxGauge::GetRange}{wxgaugegetrange}
\membersection{wxGauge::SetShadowWidth}\label{wxgaugesetshadowwidth}
\func{void}{SetShadowWidth}{\param{int }{width}}
Sets the 3D shadow width.
\wxheading{Remarks}
This method is not implemented (doesn't do anything) for most platforms.
\membersection{wxGauge::SetValue}\label{wxgaugesetvalue}
\func{void}{SetValue}{\param{int }{pos}}
Sets the position of the gauge.
This function makes the gauge switch to determinate mode, if it's not already.
\wxheading{Parameters}
\docparam{pos}{Position for the gauge level.}
\wxheading{See also}
\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.
