this class implements the scroller for scrollbars. |
55 |
it can also be used by itself for scrollbars without step-buttons. |
|
63 | 56 |
When moved, either a predefined action is performed (scrollAction), |
119 | 57 |
or a model is informed via the changeMsg (which is #value: by default). |
63 | 58 |
|
38 | 59 |
The scroller can work synchronous (i.e. every move leads to an immediate evaluation |
60 |
of the action, or asynchronous (i.e. perform action on end-of move). |
|
63 | 61 |
By default, scrollers are synchronous. Asynchronous operation makes sense, |
62 |
if the scroll operation (redraw) is expensive and takes a long time. |
|
0 | 63 |
|
127 | 64 |
This class is used both for concrete instances (vertical scrollers) |
65 |
and as an abstract superclass for horizontalScrollers, sliders and |
|
66 |
miniScrollers. |

notice: for mswindows style, we force a WRONG thumb-frame |
142 |
computation, to make the thumb have constant size; |
|
63 | 143 |
if you dont like that (I do not :-), set scrollerThumbFixHeight to false (in the StyleSheet). |
