How to add icon in RTF format?

Question

I am developing SWT widget and I have build drag and drop functionality. Whenever I drag file across it's download link should be transferred.

I have done that using following code.

Now what I want is with link, I want file icon to be displayed beside the link. For example, if it's word document , word file icon should be displayed.

final DragSource dragSource = new DragSource(tv.getTree(), DND.DROP_MOVE | DND.DROP_COPY | DND.DragOver );
                dragSource.addDragListener(new DragSourceAdapter(){
                    @Override
                    public void dragFinished(DragSourceEvent event) {
                        dragSource.dispose();
                    }

                    @Override
                    public void dragSetData(DragSourceEvent event) {
                        final TreeItem[] dndSelection = tv.getTree().getSelection();
                        final String[] sourceNames = new String[dndSelection.length];
                        String docName = "document";
                        for (int i = 0; i < dndSelection.length; i++) {
                            final TreeItem item = (TreeItem) dndSelection[i];
                            final PendingTreeNode node = (PendingTreeNode) item
                                    .getData();
                            sourceNames[i] = node.getNodeId();
                            docName = node.getName();
                        }
                        final String filePath = AlfrescoFileUtil.getFileURL(sourceNames[0]);
                        final String viewDetailLink = AlfrescoFileUtil.getSearchFileURL(sourceNames[0]);
                        final String viewDetailsLabel = "View details";
                        StringBuffer finalS = new StringBuffer();
                        finalS.append("{\\rtf1\\ansi\\ansicpg1252\\deff0\\deflang1033{\\fonttbl{\\f0\\fnil\\fcharset0 Calibri;}}{\\colortbl ;\\red0\\green0\\blue255;}{\\*\\generator Msftedit 5.41.21.2509;}\\viewkind4\\uc1\\pard\\sa200\\sl276\\slmult1\\lang9\\f0\\fs22{\\field{\\*\\fldinst{HYPERLINK \"" + filePath + "\"}}{\\fldrslt{\\ul\\cf1 " + docName + "}}}");
                        finalS.append(" | ");
                        finalS.append("{\\field{\\*\\fldinst{HYPERLINK \"" + viewDetailLink + "\"}}{\\fldrslt{\\ul\\cf1 "+ viewDetailsLabel + "}}}}}");
                        event.data = finalS.toString();
                    }
                });
                dragSource.setTransfer(new Transfer[]{RTFTransfer.getInstance()});
                dragSource.notifyListeners(SWT.DragDetect, event);

I want to display something similar to following.

but it is showing something like this now without icon

You can use the SWT Program class to find the program icon given the file extension:

Program program = Program.findProgram("file extension");

ImageData imageData = program.getImageData();

Hi, Thanks for your reply. I know how to get image in SWT, I just want to know how can I transfer that image along with link (which I am already transferring in my code above) ? – user327126 Dec 03 '15 at 23:08

Have you tried to use the event.image property of DragSourceEvent?

    return new DragSourceListener() {
        @Override
        public void dragStart(DragSourceEvent event) {
            final Image image   =   xxx.getImage(); // get image
            if (image != null)
                event.image =   image;
            //else
            //  event.doit  =   false;
        }
        @Override
        public void dragSetData(DragSourceEvent event) {
            event.data      =   xxx.getData();      // set data
        }
        @Override
        public void dragFinished(DragSourceEvent event) {
            // On MOVE operations, data should be removed
        }
    };
