- <P><STRONG>Tk::NumEntryPlain</STRONG> defines a widget for entering integer numbers.</P>
- <P><STRONG>Tk::NumEntryPlain</STRONG> supports all the options and methods that a normal
- <A HREF="../../../site/lib/Tk/Entry.html">Entry</A> widget provides, plus the following options</P>

- <DT><STRONG><A NAME="item_%2Dminvalue">-minvalue</A></STRONG><BR>
- <DD>
- Defines the minimum legal value that the widget can hold. If this
- value is <A HREF="../../../lib/Pod/perlfunc.html#item_undef"><CODE>undef</CODE></A> then there is no minimum value (default = undef).
- <P></P>
- <DT><STRONG><A NAME="item_%2Dmaxvalue">-maxvalue</A></STRONG><BR>
- <DD>
- Defines the maximum legal value that the widget can hold. If this
- value is <A HREF="../../../lib/Pod/perlfunc.html#item_undef"><CODE>undef</CODE></A> then there is no maximum value (default = undef).
- <P></P>
- <DT><STRONG><A NAME="item_%2Dbell">-bell</A></STRONG><BR>
- <DD>
- 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).
- <P></P>
- <DT><STRONG><A NAME="item_%2Dtextvariable">-textvariable</A></STRONG><BR>
- <DD>
- Reference to a scalar variable that contains the value currently
- in the <STRONG>NumEntry</STRONG>. Use the variable only for reading (see
- <A HREF="#caveats">CAVEATS</A> below).
- <P></P>
- <DT><STRONG><A NAME="item_%2Dvalue">-value</A></STRONG><BR>
- <DD>
- Specifies the value to be inserted into the entry widget. Similar
- to the standard <STRONG>-text</STRONG> option, but will perform a range
- check on the value.

- <DT><STRONG>-textvariable</STRONG><BR>
- <DD>
- <STRONG>-textvariable</STRONG> should only be used to read out the current
- value in the <STRONG>NumEntry</STRONG>.
- <P>Values set via <STRONG>-textvariable</STRONG> are not valided. Therefore
- it's possible to insert, e.g., 'abc', into the <STRONG>NumEntry</STRONG>.</P>
