Specify dragHandle CSS class

dragHandleClass="dijitTitlePaneTitle"

Rather than dragging by clicking anywhere on a widget, it is also possible to specify particular parts of the widget that are draggable, for example a title bar. To do this, set the 'dragHandleClass' to the CSS class on that draggable node. Note that below, you can only drag the title panes by dragging their title bar, not the body of the widget.
