*
* $History: CJFlatComboBox.h $
*
* ***************** Version 9 *****************
* User: Kirk Stowell Date: 5/17/99 Time: 9:24p
* Updated in $/CodeJockey/Include
* Gilberto Botaro [seafox@techno.com.br] - Added code for auto
* completion.
*
* ***************** Version 8 *****************
* User: Kirk Stowell Date: 5/03/99 Time: 10:44p
* Updated in $/CodeJockey/Include
* Fixed code ommisions.
*
* ***************** Version 7 *****************
* User: Kirk Stowell Date: 5/03/99 Time: 8:42p
* Updated in $/CodeJockey/Include
* Danilo Lax [Danilo_Lax@www2.alpeng.com] - The control is painted flat
* when the mouse leaves the box, even if the control has the focus, now
* checking for the focus in OnTimer(.
*
* Removed, unhandled msgs are processed by
* CComboBox::PreTranslateMessage(pMsg). Used reflected msgs
* BN_GETFOCUS/CBN_KILLFOCUS instead of WM_GETFOCUS/WM_KILLFOCUS.
*
* ::GetFocus() doesn't return CFlatComboBox::m_hWnd, even if the control
* has the focus (don't know why, maybe ::GetFocus() only returns the
* handle to the EditField part of the ComboBox), used flag m_bHasFocus
* instead.
*
* ***************** Version 6 *****************
* User: Kirk Stowell Date: 4/03/99 Time: 4:26p
* Updated in $/CodeJockey/Include
* Added comments and cleaned up code.
*
* ***************** Version 5 *****************
* User: Kirk Stowell Date: 1/22/99 Time: 4:26p
* Updated in $/CodeJockey/Include
* Fixed accelerator problem reported by YOSH YAMASHITA
* (yosh@muj.biglobe.ne.jp) with Matt Weagle's solution of overloading
* PreTranslateMessage().
*
* ***************** Version 4 *****************
* User: Kirk Stowell Date: 1/02/99 Time: 4:25p
* Updated in $/CodeJockey/Include
* Renamed class from CJComboBox to CCJFlatComboBox, changed DRAWSTATE to
* enum, removed method Offset(), and replaced with a direct call to
* ::GetSystemMetrics().
*
* ***************** Version 3 *****************
* User: Kirk Stowell Date: 11/02/98 Time: 4:24p
* Updated in $/CodeJockey/Include
* Added OnSetFocus(), OnKillFocus() and modified OnPaint() so the control
* remains beveled until it actually looses focus - (Vachik
* Hovhannissian).
*
* ***************** Version 2 *****************
* User: Kirk Stowell Date: 10/05/98 Time: 4:24p
* Updated in $/CodeJockey/Include
* Fixed offset bug to use GetSystemMetrics(), instead of hard coded
* values -
* Todd Brannam (tbrannam@msn.com).
*
* ***************** Version 1 *****************
* User: Kirk Stowell Date: 10/02/98 Time: 4:23p
* Created in $/CodeJockey/Include
* First release version.
