Execution environment
Supports dynamics
ProgressIndicator[x]
ProgressIndicator[x, {min, max}]
represents an active indicator used for reporting the progress. When ranges are not specified, it is assumed to be from 0 to 1.
Dynamics
First argument x can be dynamic symbols or expression. Use Offload to dynamically update the indicator, i.e.
x = 0.2;
ProgressIndicator[Offload[x], {0,10}]
then in the next cell
Do[x++; Pause[0.2];, {5}];
or as a button
Button["Increase", x++]
