The QProgressBar widget provides a horizontal progress bar.
A progress bar is used to give the user an indication of the progress of an operation and to reassure them that the application is still running.
The progress bar uses the concept of steps. You set it up by specifying the minumum and maximum possible step values, and it will display the percentage of steps that have been completed when you later give it the current step value.
You can specify the minimum and maximum number of steps with setMinimum() and setMaximum. The current number of steps is set with setValue(). The progress bar can be rewound to the beginning with reset().
If minimum and maximum both are set to 0, the bar shows a busy indicator instead of a percentage of steps. This is useful, for example, when using QFtp or QHttp to download items when they are unable to determine the size of the item being downloaded.

Reset the progress bar. The progress bar "rewinds" and shows no progress.
Sets the progressbar's minimum to min and its maximum to max.
If max is smaller than min, min becomes the only legal value.
If the current value falls outside the new range, the progressbar is reset with reset().
