<h1><center>dlgRedisplay()</center></h1>
<hr>
<dl>
<dt>
<b>Function</b>
<dd>
Redisplays the dialog after changing values.
<p>
<dt>
<b>Syntax</b>
<dd>
<tt>void dlgRedisplay(void);</tt>
<p>
<dt>
<b>Description</b>
<dd>
The <tt>dlgRedisplay</tt> function can be called to immediately refresh the
<a href=291.htm>dlgDialog</a> after changes have been made to the variables
used when defining the <a href=287.htm>dialog objects</a>.
<p>
You only need to call <tt>dlgRedisplay()</tt> if you want the dialog to be refreshed
while still executing program code. In the example below the status is changed
to "Running..." and <tt>dlgRedisplay()</tt> has to be called to make this change
take effect before the "program action" is performed. After the final status
change to "Finished." there is no need to call <tt>dlgRedisplay()</tt>, since
all dialog objects are automatically updated after leaving the statement.

<b>Example</b>
<pre>
string Status = "Idle";
int Result = dlgDialog("Test") {
dlgLabel(Status, 1); // note the '1' to tell the label to be updated!
dlgPushButton("+OK") dlgAccept(42);
dlgPushButton("Cancel") dlgReject();
dlgPushButton("Run") {
Status = "Running...";
dlgRedisplay();
// some program action here...
Status = "Finished.";
}
};
