Tk::NumEntryPlain - A numeric entry widget

       -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.

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

       The code was extracted  from  Tk::NumEntry  and  slightly  modified  by  Achim  Bohnet  <ach@mpe.mpg.de>.

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

       -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.
