! Introduction
|
|
|
|
The dropzone widget creates an area into which the user can drag files and other objects. It also supports pasting via the clipboard, although browser support is currently limited.
|
|
|
|
It sends a [[WidgetMessage: tm-import-tiddlers]] carrying a JSON representation of the tiddlers to be imported up through its parents. This message usually trapped by the NavigatorWidget which adds the tiddlers to the store and updates the story to display them.
