<h2><b>set dialog</b></h2>
<p>
<code>set dialog <i>pc fc bc oc th</i> <numeric|n></code>
<p>
Sets color properties for dialog box widgets.
<p>
<ul>
<code><i>pc</i> </code>prompt color <br>
<code><i>fc</i> </code>foreground text color <br>
<code><i>bc</i> </code>background color <br>
<code><i>oc</i> </code>outline color <br>
<code><i>th</i> </code>outline thickness <br>
<code>n </code>numeric input only (optional) <br>
</ul>
<p>
<h3>Usage Notes</h3>
<ol>
<li>If <code><i>th</i></code> is 1-5, a one-pixel border is drawn; if
it is 6 or more, a two-pixel border is drawn.
<p>
<li>Default colors are accessed by setting the colors to -1.
<p>
<li>If the numeric option is invoked, keyboard inputs are restricted
to 0-9, ., -, +, e, and E. Entered value is checked to assure it is a
rational number of the form +/-nnnn, +/-nnnn.dddd, or
+/-nnnn.ddddE+/-xxxx. This assures the returned numeric value is valid
for use by a GrADS script.
<p>

refrence page for details on execution of the dialog box widgets.
