You see - your implementation does not satisfy you.

You can use the technique shown in Demos\Delphi\Assorted\Graphics\DragImg\

to move the caret after the mouse pointer. But in this way you move a real

caret (not its drag&drop simulation).

When dragging files (or other content) over the editor, the editor

1) hides the real caret

2) draws its simulation (not blinking, visible even if the editor is not in

focus)

It's not possible to display this caret in RichViewEdit without initiating a

real (OLE) drag&drop.

Well, you can choose a hard way drawing this caret yourself.

But using the TDropTextSource component (see my previous reply), you can do

it with couple simple lines of code.

Just place it in form, register some visible component as a dragging source

for it, assign text to property.

Dragging your text will look exactly like dragging files.
