Hi
First of all, thanks for your great work.
In the data entry form sample, How can I get the values of form?
For example in Save button, how can I get the value of first name input field?

AddButton("Save", func() {
   // I want something like this
  firstName := form.getInputField("SOME_TEXT_BOX_ID").value()
})

You're right, this was missing. I don't have form element IDs so it doesn't quite work as in your example. But you now have two options:

(1) Added a change event listener to the input field in the form:

form.AddInputField("First name", "", 20, nil, func(text string) { /* handle the changed text */ })

(2) You get the field directly (by its index) and call its getter (requires a cast, though):

inputField := form.GetElement(0).(*tview.InputField)
text := inputField.GetText()

Please note that I've just committed a change which renames GetElement() to GetFormItem() for consistency reasons. I hope this won't cause too much trouble.
