class CefDragHandler

extends CefBaseRefCounted

Implement this interface to handle events related to dragging. The methods of this class will be called on the UI thread.

OnDragEnter

public virtual bool OnDragEnter( CefRefPtr< CefBrowser > browser, CefRefPtr< CefDragData > dragData, CefDragHandler::DragOperationsMask mask );

Called when an external drag event enters the browser window. |dragData| contains the drag event data and |mask| represents the type of drag operation. Return false for default drag handling behavior or true to cancel the drag event.

OnDraggableRegionsChanged

public virtual void OnDraggableRegionsChanged( CefRefPtr< CefBrowser > browser, CefRefPtr< CefFrame > frame, const std::vector< CefDraggableRegion >& regions );

Called whenever draggable regions for the browser window change. These can be specified using the '-webkit-app-region: drag/no-drag' CSS-property. If draggable regions are never defined in a document this method will also never be called. If the last draggable region is removed from a document this method will be called with an empty vector.
