<DL><DT><A NAME="-aspect"><B>-aspect</B></A></DT>
<DD>
Specifies a non-negative integer value indicating desired
aspect ratio for the text. The aspect ratio is specified as
100*width/height. 100 means the text should
be as wide as it is tall, 200 means the text should
be twice as wide as it is tall, 50 means the text should
be twice as tall as it is wide, and so on.
Used to choose line length for text if <B>width</B> option
isn't specified.
Defaults to 150.
The options <B>-width</B> and <B>-aspect</B> are directly heritated from the Tk message widget.
</DD>
</DL>
<DL><DT><A NAME="-buttons"><B>-buttons</B></A></DT>
<DD>
Specifies a list of buttons to display when <B>type</B> option is <I>user</I>.

</DD>
</DL>
<DL><DT><A NAME="-buttonwidth"><B>-buttonwidth</B></A></DT>
<DD>
Specifies the standard width of the buttons in the dialog.
</DD>
</DL>
<DL><DT><A NAME="-icon"><B>-icon</B></A></DT>

</DD>
</DL>
<DL><DT><A NAME="-justify"><B>-justify</B></A></DT>
<DD>
Specifies how to justify lines of text.
Must be one of <B>left</B>, <B>center</B>, or <B>right</B>. Defaults
to <B>left</B>.
This option works together with the <B>anchor</B>, <B>aspect</B>,
<B>padx</B>, <B>pady</B>, and <B>width</B> options to provide a variety
of arrangements of the text within the window.
The <B>aspect</B> and <B>width</B> options determine the amount of
screen space needed to display the text.
The <B>anchor</B>, <B>padx</B>, and <B>pady</B> options determine where this
rectangular area is displayed within the widget's window, and the
<B>justify</B> option determines how each line is displayed within that
rectangular region.
For example, suppose <B>anchor</B> is <B>e</B> and <B>justify</B> is
<B>left</B>, and that the message window is much larger than needed
for the text.
The the text will displayed so that the left edges of all the lines
line up and the right edge of the longest line is <B>padx</B> from
the right side of the window; the entire text block will be centered
in the vertical span of the window.

The default associated title is in english, and can be modified to set it in
another language by specifying the resource:
<PRE> *MessageDlg.<I>name</I>Title: <I>value</I></PRE>
or the equivalent tcl command:
<PRE> option add *MessageDlg.<I>name</I>Title <I>value</I></PRE>
where <I>name</I> is the name of an icon as defined in the <B>icon</B> option.
