/*
* Updown control
*
* Copyright 1997 Dimitrie O. Paun
*
* TODO:
* - subclass the buddy window (in UPDOWN_SetBuddy) to process the
* arrow keys
* - I am not sure about the default values for the Min, Max, Pos
* (in the UPDOWN_INFO the fields: MinVal, MaxVal, CurVal)
* - I think I do not handle correctly the WS_BORDER style.
* Testing:
* Not much. The following have not been tested at all:
* - horizontal arrows
* - listbox as buddy window
* - acceleration
* - base 16
* - UDS_ALIGNLEFT, ~UDS_WRAP
* - integers with thousand separators.
* 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.
* Problems:
* I do not like the arrows yet, I'll work more on them later on.
