Description:


Historic note:
     originally, ST/X had separate classes for the various entry methods;
     there were YesNoBox, EnterBox, InfoBox and so on.
     In the meantime, the DialogBox class (and therefore its alias: Dialog)
     is going to duplicate most functionality found in these classes.

     In the future, those existing subclasses' functionality is going to
     be moved fully into Dialog, and the subclasses will be replaced by dummy
     delegators. (They will be kept for backward compatibility, though).

 An EnterBox2 is like an EnterBox but with 2 action buttons.
 This is used (for example) in the search-boxes, where two ok-buttons
 'find-previous' and 'find-next' are needed in addition to the abort button.
 The protocol is like that of EnterBox, the additional buttons label
 can be set with 'okText2:aString' and its action with 'action2:aBlock'.

Class protocol:

instance creation
o  title: titleString okText1: text1 okText2: text2 abortText: abortText action1: block1 action2: block2
create and return a new EnterBox-with-2 buttons
and define its text, button-labels and actions


Instance protocol:

accessing
o  action2: aBlock
set the action to be performed when user presses the 2nd ok-button;
aBlock must be nil or a block with one argument

o  okText2: aString
set the text to be displayed in the 2nd ok-button

o  okText2: aString action2: aBlock
set the text to be displayed in the 2nd ok-button,
and its action

initialization
o  initialize
add a second ok-button (a return button)

user interaction
o  keyPress: aKey x: x y: y
return-key duplicates ok-function if acceptReturnAsOK is true

o  ok2Pressed
