Clear Buffer when closing geoprocessing widget and when reopening geoprocessing widget, display default values

GilbertoMatos

Hello!

How do I do when the geoprocessing widget when it is closed, clear all created buffers, or how to do it whenever the geoprocessing widget is opened, it is with the default values, ie as if it had been opened by the first time?

Thank you!
Gilberto.
