How can I retrieve the info if the object in a LINK description was deleted from the popupbutton (that belongs to the LINK description)? I couldn´t find out yet.![😕](http://developers.maxon.net/forum/assets/plugins/nodebb-plugin-emoji/emoji/android/1f615.png?v=6576ttlle4c ":\")
dcu->result or dcu->element isn´t NULL when I use the delete entry. So how can I check if there is a deletion?
Thanks

What "delete" entry? If you mean the "Clear" entry in the triangle menu of the LINK field, do you get a MSG_DESCRIPTION_CHECKDRAGANDDROP message when you choose it? I don't, so I cannot reproduce your problem.

yes, I mean the clear entry (sorry, german gui active). And yes I do receive a message when choosing it.
if (type == MSG_DESCRIPTION_CHECKDRAGANDDROP)
{
DescriptionCheckDragAndDrop *dcu = static_cast<DescriptionCheckDragAndDrop*>(data);
switch (dcu->id[0].id)
{
case DPT_BASE_FOUND: //LINK field ID
if(!dcu->element) GePrint("NULL");
GePrint("test ");
return TRUE;
}
}
Prints out a "test" when choosing the clear entry the first time but it never prints "NULL". -

ok, don´t know why but suddenly I don´t receive any messages anymore. But the link is still there. It isn´t cleared. So when and where do I have to set the link in the vdata BaseContainer to NULL?
BaseTag *tag = (BaseTag* )node; BaseContainer *vdata = tag->GetDataInstance(); if (type == MSG_DESCRIPTION_CHECKDRAGANDDROP) { DescriptionCheckDragAndDrop *dcu = static_cast<DescriptionCheckDragAndDrop*>(data); switch (dcu->id[0].id) { case DPT_BASE_FOUND: if(!dcu->element) GePrint("NULL"); vdata->SetLink(DPT_DRAG_OBJECT,(BaseObject* )dcu->element); break; return TRUE; } }Thanks

Arghh, ok got it. I used another ID for the container. Now I use the LINK id and it works. Thanks!

This is very strange. I only get this message during drag and drop. Where is this description used? (I used the Atom object for my tests, with this function:
Bool AtomObject::Message(GeListNode *node, LONG type, void *t_data) { if (type == MSG_DESCRIPTION_CHECKDRAGANDDROP) { DescriptionCheckDragAndDrop *dcu = (DescriptionCheckDragAndDrop* )t_data; GePrint(LongToString(GeGetTimer()) + " dcu->id[0].id: " + LongToString(dcu->id[0].id) + " dcu->element: " + LongToString((LONG) dcu->element)); } return TRUE; })
