afair, qt and gtk2 have default result for that and escape key (you
can set on dialog what is the value of default result for [X] and
escape), result should be mrCancel in any case.

The current result for Escape and [x] (at least under GTK2) is mrOK
which is very misleading.
But I have a slightly different suggestion:
1- This should apply to any modal form, not only MessageDlg and
WidgetSet.PromptUser.
2- Escape key should first check if any button has Cancel=true, and use
that button's modal result. Otherwise, mrCancel is in order as the user
is running away from answering the dialog.
3- [x] should either return mrCancel, or mimic the Escape key. The
latter is the more logical choice, as the programmer has intentionally
defined the action (by setting a button's Cancel to true) if the user
wants to run away.
