<dl>
<dt><b>NAME</b></dt>
<dd><code>mentry::ipAddrMentry</code> – Create and manipulate mentry
widgets for IP addresses</dd>
<dt class="tm"><b>SYNOPSIS</b></dt>
<dd>
<pre>
<b>mentry::ipAddrMentry</b> <i>pathName</i> ?<i>options</i>?
</pre>
</dd>
<dt><b>DESCRIPTION</b></dt>
<dd>This command creates a new mentry widget <code><i>pathName</i></code>
for displaying and editing IP addresses in the standard dotted-decimal
notation. The supported <code><i>options</i></code> are the same as
in the case of the <code><b><a href=
"mentryWidget.html">mentry::mentry</a></b></code> command.</dd>
<dd class="tm">The command sets the <code><b>type</b></code> attribute of
the widget to the value <code>"IPAddr"</code> and returns the name of the
newly created widget.</dd>
<dt class="tm"><b>DEFAULT BINDINGS</b></dt>
<dd>The <code><b>mentry::ipAddrMentry</b></code> command defines five new
keyboard bindings for the entry components of the mentry widget it
creates: The <code>Up</code> key increments the entry's value by 1 if
the latter is less than 255. Similarly, the <code>Down</code> key
decrements the entry's value by 1 if the latter is greater than 0.
The <code>Prior</code> key increments the entry's value by at most 10 if
the latter is less than 255. Similarly, the <code>Next</code> key
decrements the entry's value by at most 10 if the latter is greater than
0. If the entry is empty then all of these keys insert the value
<code>0</code> into the entry. Finally, <code>Control-v</code>
(<code>Command-v</code> on the Mac) pastes the current contents of the
clipboad into the mentry, provided that it is a valid IP address.</dd>
<dd class="tm">The actions performed by the <code>Up</code> and
<code>Down</code> keys can also be triggered with the aid of the mouse
wheel or a two-finger gesture on the touchpad. In addition, on Mac OS
X/11+ Aqua, the actions performed by the <code>Prior</code> and
<code>Next</code> keys are also triggered by the
<code><b><Option-MouseWheel></b></code> event. The same holds
true on all windowing systems if the Tk version is 8.7a4 or later, where
the <code><b>Option</b></code> modifier is bound to the <code>Option</code>
key on Mac OS X/11+ and to the <code>Alt</code> key on Windows and
X11.</dd>

command (this is checked by examining the widget's <code><b>type</b></code>
