从/在webview中拖放文件 [英] Drag/Drop File from/in webview

问题描述

我正在做一个应用程序，像Mac邮件
，如果我们在消息区域中删除一个文件，然后该文件作为附件文件
，我们可以拖动该文件到桌面和双点击文件打开它。
我使用webview（我认为webview是用于mac邮件）

推荐答案

将NSWebView子类化并实现NSDraggingDestination。我建议您阅读文档的拖放编程主题部分，了解更多关于如何正确注册NSPasteboard类型的文档。 （在10.6之前的OS X的NSFilenamesPboardType）

Subclass the NSWebView and implement NSDraggingDestination. I recommend you read thru the "Drag and Drop Programming Topics for Cocoa" section of the documentation to learn more about how to properly register for the NSPasteboard types you want. (NSFilenamesPboardType for OS X before 10.6)
