Dear all,
ButtonController has a addReadonly() feature that allows to control
which widgets should be disabled in read-only mode. It add the widgets
to a read_only_ vector<widget>, but this vector is never used? Why?
The answer is that the code was disabled a long time ago, and (partly)
removed.

Remove code that has not been used for 13 years.
The better answer, though, is that the disabling clashed with hand-made
disabling and got disabled rather than fixed.

ButtonController.cpp: fix a bug introduced in r20018: don't enable
all widgets in the dialog, see
http://www.mail-archive.com/lyx-devel@lists.lyx.org/msg128222.html
The archive above explains that this enabling/disabling clashes with
explicit disabling like in the Box dialog.
So the very unsatisfying situation is that we have code in dialogs which
annotates which widgets should be disabled in read-only mode, but these
calls do nothing.
Any bright idea on how to fix this?
I see two approaches:
1/ add a ButtonController::setDisabled(widget, bool) and use that
everywhere instead of explicit calls to QWidget::setEnabled
2/ consider that ButtonController is already ugly enough and replace all
addReadOnly calls with proper hand-made setEnabled calls on the relevant
widgets.
Any idea from people who know more than I do about dialogs?
