setDragEnabled back to summary

setDragEnabled	back to summary
public void setDragEnabled(boolean b) Sets the `dragEnabled` property, which must be `true` to enable automatic drag handling (the first part of drag and drop) on this component. The `transferHandler` property needs to be set to a non-`null` value for the drag to do anything. The default value of the `dragEnabled` property is `false`. When automatic drag handling is enabled, most look and feels begin a drag-and-drop operation when the user presses the mouse button over the preview panel. Some look and feels might not support automatic drag and drop; they will ignore this property. You can work around such look and feels by modifying the component to directly call the `exportAsDrag` method of a `TransferHandler`. Parameters b:boolean the value to set the `dragEnabled` property to Annotations @BeanProperty bound:false description:Determines whether automatic drag handling is enabled.

public void setDragEnabled(boolean b)

Sets the dragEnabled property, which must be true to enable automatic drag handling (the first part of drag and drop) on this component. The transferHandler property needs to be set to a non-null value for the drag to do anything. The default value of the dragEnabled property is false.
