Hi,

drag and dropping native files from Windows desktop to my Eclipse RCP
application works just fine on Windows, but not on my version of Linux
(SimplyMEPIS 3.3 using Konqueror and KDE) - I get no drag/drop events at all
dragging files from Konqueror to my RCP app. Are there issues?

Are you registering for the type FileTransfer? There does not seem to be a
standard format used by the various file manipulation tools on Linux. I
have implemented support for text/uri-list but it appears that many
applications have their own formats such as x-special/gnome-copied-files. I
need to investigate more of these formats and see if I can support them.
You can run the ClipboardExample (org.eclipse.swt.examples) and it will show
you a list of formats that have been placed on the Clipboard when you copy a
file from one of the external tools. Drag and Drop generally supports the
same formats as the clipboard. Enter a bug report against Platform SWT if
there is a specific format you want to see supported. (e.g. see
https://bugs.eclipse.org/bugs/show_bug.cgi?id=86569)

Hi,

yes I've been using FileTransfer:

protected void registerDragDrop() {

int operations = DND.DROP_COPY | DND.DROP_DEFAULT;
DropTarget target = new DropTarget(getControl(), operations);

Transfer[] types = new Transfer[] { FileTransfer.getInstance() };
target.setTransfer(types);

target.addDropListener(new DropTargetListener() {
public void dragEnter(DropTargetEvent event) {
if(event.detail == DND.DROP_DEFAULT) {
if((event.operations & DND.DROP_COPY) != 0) {
event.detail = DND.DROP_COPY;
}
else {
event.detail = DND.DROP_NONE;
}
}
}

public void dragLeave(DropTargetEvent event) {
}

public void dragOperationChanged(DropTargetEvent event) {
if(event.detail == DND.DROP_DEFAULT) {
if((event.operations & DND.DROP_COPY) != 0) {
event.detail = DND.DROP_COPY;
}

else {
event.detail = DND.DROP_NONE;
}

}
}

public void dragOver(DropTargetEvent event) {
event.feedback = DND.FEEDBACK_SELECT | DND.FEEDBACK_SCROLL |
DND.FEEDBACK_EXPAND;
}

public void drop(DropTargetEvent event) {
if(FileTransfer.getInstance().isSupportedType(event.currentD ataType)){
String[] files = (String[])event.data;
handleFilesDropped(files, event.item);
}

}

public void dropAccept(DropTargetEvent event) {
}

});

I found the problem. I also needed to register the DND.DROP_MOVE operation
as well as DND.DROP_COPY. So, my mistake.

Thanks very much for taking the time to reply, Veronika. Playing with the
ClipboardExample showed me that something was
wrong in my code, not Eclipse's.
