Historic note:
|
|
|
52 |
originally, ST/X had separate classes for the various entry methods;
|
|
|
53 |
there were YesNoBox, EnterBox, InfoBox and so on.
|
|
|
54 |
In the meantime, the DialogBox class (and therefore its alias: Dialog)
|
|
|
55 |
is going to duplicate most funcionality found in these classes.
|
|
|
56 |
|
|
|
57 |
In the future, those existing subclasses' functionality is going to
|
|
|
58 |
be moved fully into Dialog, and the subclasses will be replaced by dummy
|
|
|
59 |
delegators. (They will be kept for backward compatibility, though).
|
|
|

|

An EnterBox2 is like an EnterBox but with 2 action buttons.
|
|
|
62 |
This is used (for example) in the search-boxes, where two ok-buttons
|
|
|
63 |
'find-previous' and 'find-next' are needed in addition to the abort button.
|
|
60
|
64 |
The protocol is like that of EnterBox, the additional buttons label
|
|
|
65 |
can be set with 'okText2:aString' and its action with 'action2:aBlock'.
