DESCRIPTION

16       A slider control object. This object holds a value in d2, in the  range
17       from 0 to d1. It will display as a vertical slider if h is greater than
18       or equal to w, otherwise it will display as a horizontal slider. The dp
19       field  can contain an optional bitmap to use for the slider handle, and
20       dp2 can contain an optional callback function,  which  is  called  each
21       time d2 changes. The callback function should have the following proto‐
22       type:
23
24          int function(void *dp3, int d2);
25
26       The d_slider_proc object will return the value of  the  callback  func‐
27       tion.
