The Drag and Drop Component Suite is a freeware VCL component library that enables your Delphi and CBuilder applications to support COM based drag and drop and integrate with the Windows clipboard. The drag and drop system that is built into the VCL, is limited in that it only supports drag and drop within the same application. If you need to drag data from your application to other applications e. Word, Explorer or Outlook, or if you need to be able to accept data dropped from other application e. Explorer, you have to use COM based drag and drop.

Every drag and drop operation involves two objects A drop source and a drop target.

IDANY or another standard ID v2. Widgets. You can make your own IDs, but there is no reason to do that. The drop source provides the data to be dragged, and the drop target accepts the dragged data. Likewise there are basically two sets of components in the Drag and Drop Component Suite Drop source components and drop target components. Most of the source and target components are specialized to handle just one type of data, but a few of the components supports a wider range of data types or are completely generic. In addition to the drag and drop components, the Drag and Drop Component Suite also includes components that can be used to build Windows Shell Extensions. While these components arent all related to Drag and Drop, they benefit from the Drag and Drop Component Suite framework and allow you to write Windows Shell Extensions with very little code. But most important I had a lot of fun writing them. Features Freeware with full source code included. Enables COM drag and drop of any kind of data between applications. Copy, Move and Link operations. Clipboard Copy, Cut and Paste support. Support and implement advanced features such as Delete on paste and Optimized Move. Drag image support. Supports both Ansi and Unicode data formats, regardless of the version of Delphi used. Supports asynchronous transfer. Both on the source and target side. Automatic scrolling of the target window during the drag operation. Relatively simple to derive custom drag and drop components to support other data formats. Extensive, context sensitive help file and detailed demo applications. Implements the IDrop. Source, IDrop. Target, IData. Object and IAsync. Operation interfaces. Compatible with Delphi 5 through Delphi 2. Components. The Drag and Drop Component Suite contains the following components Drop Sources Drop Targets. TDrop. File. Source Enables you to drag files and shortcuts from your application to other applications. TDrop. Text. Source Enables you to drag text from your application to other applications. TDrop. BMPSource Enables you to drag bitmaps from your application to other applications. TDrop. URLSource Enables you to drag URLs from your application to other applications. TDrop. PIDLSource Enables you to drag PIDLs files, folders, shell objects from your application to other applications. TDrop. Empty. Source A basic drop source component that does not support any data formats on its own. Can be extended with support for any data format through the use of a TData. Format. Adapter component. TDrop. File. Target Enables your application to accept files and shortcuts dropped on it from other applications. TDrop. Text. Target Enables your application to accept text dropped on it from other applications. TDrop. BMPTarget Enables your application to accept bitmaps dropped on it from other applications. TDrop. Meta. File. Target Enables your application to accept meta files dropped on it from other applications. TDrop. URLTarget Enables your application to accept URLs dropped on it from other applications. TDrop. Combo. Target Enables your application to accept files, shortcuts, text, URLs, meta files, and bitmaps dropped on it from other applications. The component is basically all the above components rolled into one. TDrop. Image. Target Enables your application to accept meta files, and bitmaps dropped on it from other applications. The component is basically the TDrop. BMPTarget and the TDrop. Meta. File. Target components rolled into one. TDrop. PIDLTarget Enables your application to accept PIDLs files, folder, shell objects dropped on it from other applications. TDrop. Empty. Target A basic drop target component that does not support any data formats on its own. Can be extended with support for any data format through the use of a TData. Format. Adapter component. Shell Extensions Additional. TDrop. Handler Implements the necessary interfaces required to build Drop Handler shell extensions. A Drop Handler shell extension is used to turn file classes e. TDrag. Drop. Handler Implements the necessary interfaces required to build Drag. Drop Handler shell extensions. A Drop Handler shell extension is used to extend the popup menu which is displayed by the shell when a file is dragged with the right mouse button. TDrop. Context. Menu Implements the necessary interfaces required to build Context Menu Handler shell extensions. A Context Menu Handler is used to extend the shell popup menu which is displayed when a file is right clicked. TData. Format. Adapter Used to extends source or target components with support for arbitrary clipboard formats. TDrop. Dummy Helper component used to display drag images. License. This work is licensed under a.

The library has been tested with the following versions of Delphi If you can confirm compatibility with any of the untested versions of Delphi or C Builder for that matter, please let me know and I will update the table. C Builder. I have done absolutely no testing with C Builder so I dont know if the code works with it or not. That said, according to feedback I have received, the current release should work with C Builder. Download Old versions. Old versions can be found on the downloads page. Installation.
