The Fl_Scrollbar widget displays a slider with arrow buttons at
|
|
|
|
the ends of the scrollbar. Clicking on the arrows move up/left and
|
|
|
|
down/right by linesize(). Scrollbars also accept FL_SHORTCUT events:
|
|
|
|
the arrows move by linesize(), and vertical scrollbars take Page
|
|
|
|
Up/Down (they move by the page size minus linesize()) and Home/End
|
|
|
|
(they jump to the top or bottom).
|
|
|
|
|
|
|
|
Scrollbars have step(1) preset (they always return integers). If
|
|
|
|
desired you can set the step() to non-integer values. You will then
|
|
|
|
have to use casts to get at the floating-point versions of value()
|
|
|
|
from Fl_Slider.
