Greetings to all!

I want to drag and drop the file onto the form so that its icon is
shown when dragging. As in the picture in the attachment. It's not
necessary to display the thumbnail or contents of the file, I just
want to see icon and name.

It's possible to implement?

p.s. File should be dragged to a specific location, i.e. to BCPanel
(dropFilePanel).

Hi Wargan,
For files you already have a default icon implemented(image1).
OnDropFiles(Form1) do something like this:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TForm1.FormDropFiles(Sender: TObject; const FileNames: array of
String);var  I: Integer;begin  for I := Low(FileNames) to
High(FileNames) do  begin      //process each file  end;end;
For more advanced drawing see the "Example projects" in the "Tool
menu"(Image2)
