Detailed Description

CNumSpinCtrl is a spin control for real numbers that can be combined with a Numeric Edit Control.

Class CNumSpinCtrl enables you to:

• get and set the range to spin and the delta, e.g. SetRangeAndDelta(),
• set the format string to represent the number in a buddy control, SetFormat()
• get and set a new position, e.g. GetPos(), operator double(), operator=()
• increase or decrease the position with delta, operator++(), operator--()

Make sure that the control is included in method DoDataExchange() of the dialog classes where you use the spin control.

Class CNumSpinCtrl is a slightly modified version of the class CNumSpinCtrl by Damir Valiulin [NUMSPINCTRL].

Accessors
void	GetRangeAndDelta (real_type &lower, real_type &upper, real_type &delta)
	obtain the lower and higher limits and the delta value.
double	GetPos ()
	the current position.
integer_type	GetPosInt ()
	the current position as integer.
Mutators
void	SetRangeAndDelta (real_type lower, real_type upper, real_type delta)
	set the lower and higher limits and the delta value.
void	SetPos (double value)
	set the new position.
void	SetPos (int value)
	set the new positon.
void	SetPos (long value)
	set the new positon.
void	SetPos (unsigned long value)
	set the new positon.
void	SetFormat (LPCTSTR lpszFormatString=NULL)
	set the printf-like format string (NULL yields "%g").
void	Select ()
	focus this control and select its contents.
Protected Member Functions
virtual void	PreSubclassWindow ()
	allow other necessary subclassing to occur before the window is subclassed.
void	InitSpinCtrl ()
	check that Set-Buddy-Integer is unset and set the control's range via SetRangeAndDelta().
void	SetIntPos (real_type pos)
	set the underlying SpinButtonCtrl's position.
void	SetValueForBuddy (real_type val)
	set the contents of the buddy edit control.
afx_msg BOOL	OnDeltapos (NMHDR *pNMHDR, LRESULT *pResult)
	handle position-change message, set buddy contents via SetValueForBuddy().
afx_msg int	OnCreate (LPCREATESTRUCT lpCreateStruct)
	handle create message, calls InitSpinCtrl().

	minimum value
CString	m_csFormat
	printf format string
