this class implements vertical scrollbars with scroller and |
|
40 |
2 step-scroll buttons. when moved or stepped, it performs a |
|
41 |
predefined action. |
|
42 |
||
43 |
The action is specified by: the block to be evaluated for step-up |
|
585 | 44 |
aScrollBar scrollUpAction:aBlock |
45 |
(scrollLeftAction for hor-Scrollbars) |
|
0 | 46 |
|
585 | 47 |
aScrollBar scrollDownAction:aBlock the block to be evaluated for step-down |
48 |
(scrollRightAction for hor-Scrollbars) |
|
38 | 49 |
|
585 | 50 |
aScrollbar scrollAction:aBlock the block to be evaluated for scroll |
51 |
passing percentage as argument. |
|
38 | 52 |
|
53 |
Scrollbars can scroll syncronous (i.e. every movement is notified immediately via the |
|
54 |
scrollAction) or asynchronous (i.e. only one notification takes place at the end of the movement). |
|
55 |
The choice is up to the user of the scrollbar (typically, views which are complicated to redraw, |
|
56 |
will set it to asynchronous.) |
|
57 |
||
58 |
Most often scrollbars are used hidden with ScrollableView or HVScrollableView (i.e. you |
|
59 |
dont have to care for all the details). |
|
128 | 60 |
|
61 |
The scrollBars and scrollers protocols have been made similar enough to |
|
62 |
allow transparent use of either a scroller or a scrollBar in applications. |
