Below are two progress bars. \
|
|
The top one is a \\u201Cdeterminate\\u201D progress bar, \
|
|
which is used for showing how far through a defined task the program has got. \
|
|
The bottom one is an \\u201Cindeterminate\\u201D progress bar, \
|
|
which is used to show that the program is busy \
|
|
but does not know how long for. Both are run here in self-animated mode, \
|
|
which can be turned on and off using the buttons underneath.
