ArrowButtons display an arrow as their label; they are mainly
|
|
38
|
46 |
used for scrollbars, but can be useful on their own in some applications.
|
|
59
|
47 |
Beside the contents, their default behavior is to perform their action
|
|
|
48 |
when pressed - not (as is the default for normal buttons) when released.
|
|
38
|
49 |
|
|

|
50 |
Indivdual ArrowButtons can be created by sending one of:
|
|
59
|
51 |
ArrowButton upIn:aView /downIn: / leftIn: or rightIn:
|
|
38
|
52 |
passing the parent view as argument.
