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