NG Drag&DropPack
Introduction
LMD NG Drag&Drop is a part of Next Generation (NG) package suite. All these packages are based on new IDE and language features of latest Delphi IDE versions. NG Drag&Drop provides the ability to exchange data with other applications via standard Windows OLE drag&drop protocol. There are a lot of common applications, which uses Windows drag&drop:
- Windows Explorer (shell) - allows to drag/receive real or virtual file objects.
- MS Office application (Word, Excel, Outlook, ect), WordPad, other text editors - allows to drag/receive ANSI, Unicode, RTF and HTML text data, images, metafiles, files.
- Internet Browsers (Internet Explorer, Google Chrome, ect) - allows to drag/receive URLs (to open new page or as a bookmark), text (as search query to open new page), files (as downloads).
- Adobe Photoshop - allows to drag/receive images.
- many other high quality Windows applications actually support drag&drop.
NG Drag&Drop provides Fluent Interface API, which is an easy and very convenient way for supporting drag&drop operations, without placing any component on the form. API supports both source and target parts. For example, data dragging (source part) can be initiated as follows:
NGDropSource.AddText('My text').AddUnicodeText('My text').Execute;
Following is a short feature list of NG Drag&Drop package:
-
TNGDropSource component, which allows to drag data from customer’s application to any other drag&drop enabled applications.
-
TNGDropTarget component, which allows to receive data from any drag&drop enabled application.
-
