<short>Drag and Drop</short>
<descr><p>Drag and drop provides a simple visual mechanism which users can use
to transfer information between and within applications. [In the literature this
is referred to as a "direct manipulation model".] Drag and drop is similar in
function to the clipboard's cut and paste mechanism.
</p>
<p>This topic describes the basic drag and drop mechanism and outlines the
approach used to enable it in custom widgets.
</p>
