Usage

Inspect the demo.py code for examples of how to use ** PyQtLineEditProgressBar** and read the user manual documentation.

Caveat

This package uses Qt Palettes and LinearGradients to implement the progressbar in the background color of the LineEdit widget.

If you spend anytime whatsoever reading the Qt documentation on Palettes, it clearly states multiple times that the use of Palettes and Qt Style Sheets should not be mixed.

So its highly likely that if this package is used as part of an application that changes color themes via Qt Style Sheets there might be compatibility issues.

I would like to understand and solve this issue in the future, if possible. But at the moment it is not clear to me how to implement something like this only using Qt's style sheets.
