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.

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.
