Detailed Description

Implement this interface to handle events related to dragging.

The methods of this class will be called on the UI thread.

Member Typedef Documentation

◆ DragOperationsMask

typedef cef_drag_operations_mask_t CefDragHandler::DragOperationsMask

Member Function Documentation

◆ OnDragEnter()

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

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.

◆ OnDraggableRegionsChanged()

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

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.
