This demo creates a semitransparent window at the bottom right corner of the screen. The user can drop the dragged data into this window.
The demo opens a viewer window for the dropped data.

The following formats are supported:
- RVF
- RTF
- Hyperlink
- Unicode text
- Text
- Bitmap
- Metafile
- Files (RVF, RTF, text, image)

This demo contains a new component, inherited from TRichView: TRichViewTarget. It accepts the dropped data and loads it in another TRichView or TRichViewEdit (specified in its Receiver property).

[+] History of updates: 2008-Dec-9: for compatibility with TRichView 11 and Delphi 2009
2011-Oct-1: for compatibility with TRichView 13.4
2018-Apr-8: for compatibility with TRichView 17.3

Updated.
New event: OnOleDragOver - allows to choose areas where user can drop data
New event: OnOleDropNotAccepted - called after OnOleBeforeDrop if the dropped data are not accepted (for example, dropping files of unknown formats)
Improved: In OnOleBeforeDrop you can disallow dropping (basing on the cursor coordinates)
