Hi rivo.

First off, thanks for this great library.

I have a lot of form's that I add input fields to, drop downs, etc, using the AddXXXX receiver methods (AddInputTextField, AddDropDown) etc. One thing I've noticed is that I can't seem to pull out the selected default value when a user doesn't change the fields value:

tmpForm.AddInputField("API Username", apiUserName, 256, nil, func(text string) { configStruct.ApiUsername = text })

This works well if the user changes the value in the input field, as the function will copy the text over to the configStruct.ApiUsername, however using the AddXXXX receivers, there does not appear to be a way to get the text out when referencing by label name:

`apiUsernameField := tmpForm.GetFormItemByLabel("API Username")

apiUsername := apiUsernameField.GetXXXXXXX <-- no methods to get value
`
I can get the field label "API Username" but there does not appear to be a way to get the value out of the FormItem interface?

The workaround I have found to work is to use the tview.NewInputField() method, and then assign everything to a variable, but for large forms it really adds a lot of clutter.

The FormItem interface is for all form items. So the type of "value" is not the same for the different form items. (It may be a "bool" for checkboxes or a "string" for input fields.) If you want to access an input field's value directly, you'll have to do a cast:

apiUsernameField := tmpForm.GetFormItemByLabel("API Username").(*tview.InputField)
apiUsername := apiUsernameField.GetText()

Please let me know if this answers your question.
