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