ipentry(n) An IP address entry widget ipentry(n)
__________________________________________________________________________________________________________________________________________________NAME
ipentry - An IP address entry widget
SYNOPSIS
package require Tcl 8.4
package require Tk 8.4
package require ipentry ?0.3?
::ipentry::ipentry pathName ?option value...?
::ipentry::ipentry6 pathName ?option value...?
pathName complete
pathName get
pathName insert iplist
pathName icursor index
pathName configure option value...
pathName cget option
_________________________________________________________________DESCRIPTION
This package provides a widget for the entering of a IP address.
::ipentry::ipentry pathName ?option value...?
Creates a new IPv4 ipentry widget and configures it with the given options and their values.
::ipentry::ipentry6 pathName ?option value...?
Creates a new ipentry widget for the entry of an IPv6 address. All options are the same as the IPv4 widget.
Each widget created with the command above supports the following methods:
pathName complete
Returns a boolean value. True indicates that the entry contains a complete IP address, meaning all fields have a value. In some
cases IPv6 address are valid when fields are missing. You will need to do your own validation to detect this.
pathName get
Returns the contents of the entry as a list consisting of 4 or 8 elements.
pathName insert iplist
IPv4 Takes a list of 4 elements and inserts one into each quad of the entry, in order. All values in the list must be empty or
integers. Values outside the range 0 to 255 are modified to be within the range. IPv6 Takes a list of 8 elements and inserts one
into each quad of the entry, in order. All values in the list must be empty or 1 to 4 hex digits.
pathName icursor index
Sets the position of the widgets insertion cursor. Only integer values between 0 and 15 are valid for ipentry and 0 to 31 for ipen-
try6. Setting the icursor will only have an effect if the widget already has the input focus.
pathName configure option value...
Modifies the configuration of the widget. For options and their meaning see the widget options section.
pathName cget option
Returns information about the current configuration of the widget, for the specified option. For options and their meaning see the
widget options section.
