Class Description

 TGNumberEntry, TGNumberEntryField and TGNumberFormat                 
 TGNumberEntry is a number entry input widget with up/down buttons.   
 TGNumberEntryField is a number entry input widget.                   
 TGNumberFormat contains enum types to specify the numeric format.    
 The number entry widget is based on TGTextEntry but allows only      
 numerical input. The widget support numerous formats including       
 integers, hex numbers, real numbers, fixed fraction reals and        
 time/date formats. The widget also allows to restrict input values   
 to non-negative or positive numbers and to specify explicit limits.  
 The following styles are supported:                                  
 kNESInteger:        integer number                                   
 kNESRealOne:        real number with one digit (no exponent)         
 kNESRealTwo:        real number with two digits (no exponent)        
 kNESRealThree:      real number with three digits (no exponent)      
 kNESRealFour:       real number with four digits (no exponent)       
 kNESReal:           arbitrary real number                            
 kNESDegree:         angle in degree:minutes:seconds format           
 kNESMinSec:         time in minutes:seconds format                   
 kNESHourMin:        time in hour:minutes format                      
 kNESHourMinSec:     time in hour:minutes:seconds format              
 kNESDayMYear:       date in day/month/year format                    
 kNESMDayYear:       date in month/day/year format                    
 kNESHex:            hex number                                       
 The following attributes can be specified:                           
 kNEAAnyNumber:      any number is allowed                            
 kNEANonNegative:    only non-negative numbers are allowed            
 kNEAPositive:       only positive numbers are allowed                
 Explicit limits can be specified individually:                       
 kNELNoLimits:       no limits                                        
 kNELLimitMin:       lower limit only                                 
 kNELLimitMax        upper limit only                                 
 kNELLimitMinMax     both lower and upper limits                      
 TGNumberEntryField is a plain vanilla entry field, whereas           
 TGNumberEntry adds two small buttons to increase and decrease the    
 numerical value in the field. The number entry widgets also support  
 using the up and down cursor keys to change the numerical values.    
 The step size can be selected with control and shift keys:           
 --                  small step (1 unit/factor of 3)                  
 shift               medium step (10 units/factor of 10)              
 control             large step (100 units/factor of 30)              
 shift-control       huge step (1000 units/factor of 100)             
 The steps are either linear or logarithmic. The default behaviour    
 is set when the entry field is created, but it can be changed by     
 pressing the alt key at the same time.                               
 Changing the number in the widget will generate the event:           
 kC_TEXTENTRY, kTE_TEXTCHANGED, widget id, 0.                         
 Hitting the enter key will generate:                                 
 kC_TEXTENTRY, kTE_ENTER, widget id, 0.                               
 Hitting the tab key will generate:                                   
 kC_TEXTENTRY, kTE_TAB, widget id, 0.
