NAME
       Tk::NumEntryPlain - A numeric entry widget

SYNOPSIS
       use Tk::NumEntryPlain;

DESCRIPTION
       Tk::NumEntryPlain defines a widget for entering integer numbers.

       Tk::NumEntryPlain supports all the options and methods that a normal Entry widget provides, plus the following options

STANDARD OPTIONS
       -repeatdelay -repeatinterval

WIDGET-SPECIFIC OPTIONS
       -minvalue
	   Defines the minimum legal value that the widget can hold. If this value is "undef" then there is no minimum value (default = undef).

       -maxvalue
	   Defines the maximum legal value that the widget can hold. If this value is "undef" then there is no maximum value (default = undef).

       -bell
	   Specifies a boolean value. If true then a bell will ring if the user attempts to enter an illegal character into the entry widget, and
	   when the user reaches the upper or lower limits when using the up/down buttons for keys (default = true).

       -textvariable
	   Reference to a scalar variable that contains the value currently in the NumEntry.  Use the variable only for reading (see "CAVEATS"
	   below).

       -value
	   Specifies the value to be inserted into the entry widget. Similar to the standard -text option, but will perform a range check on the
	   value.

       -command
	   A callback which is called if <Return> is pressed.

       -browsecmd
	   A callback which is called every time an increment or decrement happens in the entry widget.

WIDGET METHODS
       $numentry->incdec(increment)
	   Increment the value of the entry widget by the specified increment. If increment is 0, then perform a range check.

CAVEATS
       -textvariable
	   -textvariable should only be used to read out the current value in the NumEntry.

	   Values set via -textvariable are not valided. Therefore it's possible to insert, e.g., 'abc', into the NumEntry.
