Update values on the fly based on user input, possible?

Question

Hi,

I need to updates values of "Column B" based on "Column A" and an user input.

For that I would need to present the user with some kind of "Calculate" button and a wizard where the user will enter a desired % and then Column B values will appear.

I am not asking exactly how can I do this, right now I would like to know if this is possible? Where should I look at? How can I create a "calculate" button?

Any tip will be appreciated!

you can use @api.onchange('field_a')

@api.onchange('field_a')
def _onchange_field_a(self):
if self.field_a:
self.field_b = some_value_after_calculation

This method will be called whenever there is a change in value of field_a and will update value of field_b. No button is required.
