* Updown control
|
|
*
|
|
* Copyright 1997 Dimitrie O. Paun
|
|
*
|
|
* TODO:
|
|
* - I think I do not handle correctly the WS_BORDER style.
|
|
* (Should be fixed. <ekohl@abo.rhein-zeitung.de>)
|
|
*
|
|
* Testing:
|
|
* Not much. The following have not been tested at all:
|
|
* - horizontal arrows
|
|
* - listbox as buddy window
|
|
* - acceleration
|
|
* - base 16
|
|
* - integers with thousand separators.
|
|
* (fixed bugs. <noel@macadamian.com>)
|
|
*
|
|
* Even though the above list seems rather large, the control seems to
|
|
* behave very well so I am confident it does work in most (all) of the
|
|
* untested cases.
