This PR includes the commits for #300 because it is too hard to use without the
FormItemArgs(IMO.)This adds a
.validproperty and a.SetValidateFuncto each ofInputField,PasswordField,DropDownandCheckboxstructs.It also adds a
ValidatePrimitive(Primitive,EventKey)method toApplicationand calls that method inside<application>.Run()just before invoking the primitive'sInputHandler().It will only call the validation callback when
event.Key()is one oftcell.KeyEnter,tcell.KeyTab,tcell.KeyBacktabortcell.KeyEscape.If the callback returns
false, it bypasses the input handler and keeps focus on the just now invalidated field.Please consider accepting this update.
