a view for text which is known to be smalltalk code.
|
|
|
52 |
It adds explain to the menu, and defines another action:
|
|
|
53 |
explainAction to be performed for explain.
|
|
32
|
54 |
|
|
125
|
55 |
This action is to be defined by the user of this view
|
|
38
|
56 |
(i.e. ususally the owning browser)
|
|
121
|
57 |
|
|
125
|
58 |
If used with a model, accept sends the changeMsg to it (as defined in EditTextView).
|
|
121
|
59 |
(however, it is possible to define moth changeMsg and acceptAction)
|
|
123
|
60 |
|
|
|
61 |
|
|
|
62 |
Caveat:
|
|
|
63 |
in this version, CodeView does not yet support MVC setups for doIt
|
|
|
64 |
and explain.
|
|
|
65 |
If required, simulate this by setting the doItAction and
|
|
|
66 |
explainAction, to notify the model manually about whats going on.
