QIOSTextInputResponder: factor out the "read-only" part to a QIOSTextResponder base class

Browse Source

QIOSTextInputResponder has two responsibilities; It takes care of
handling text input from UIKit, and to implement first responder
actions related to the edit menu, like copy and paste.

Currently the responder offers both writable (paste) and
readable (select, copy) actions. Because of the former, it means
that it can only be used for focus objects that accepts text input.

Since we also want to be able to show an edit menu for selections
done on a read-only input field, this patch will factor out the
read-only actions we want for that case into a QIOSTextResponder
base class. An instance of this class can be used as first responder
for a focus object that has read-only text, but otherwise doesn't
support text input. This part is implemented in a subsequent patch.

The remaining set of writeable actions, together with input method
handling, will continue to be in the QIOSTextInputResponder subclass.
