| 37 | <p> This example demonstrates how to create an extension dialog.
|
|---|
| 38 | <p> Essentially all that is necessary is to create a standard dialog
|
|---|
| 39 | and then create a <a href="qwidget.html">QWidget</a> form to be used as the extension. See
|

| 40 | the article in <a href="http://doc.trolltech.com/qq/">Qt
