man Tk::NumEntryPlain (3): 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.
