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