Drag&drop from GeUserArea [SOLVED]

If I remember correctly, this will need to be handled by a SceneHook plugin. Override the Message() method and check for these (as needed) :
MSG_DESCRIPTION_CHECKDRAGANDDROP ``MSG_MATERIALDRAGANDDROP ``MSG_DRAGANDDROP -

I was curious about this. So I gave it a try myself.
But I can't get the messages to fire in my SceenHook plugin for some reason.
What else is needed for a message to execute?Bool MySceneHook::Message(GeListNode *node, LONG type, void *data) { BaseDocument *doc = GetActiveDocument(); BaseObject *obj = doc->GetFirstObject(); if(!obj) return FALSE; MaterialDragAndDrop mdd; //Create an instance of the MaterialDragAndDrop struct (class) mdd.op = obj; //Point to this object //if(mdd.op) GePrint(mdd.op->GetName()); //works..But prints all the time. Not just when dropping a material on the obj if(type == MSG_MATERIALDRAGANDDROP) { GePrint(mdd.op->GetName()); //<---Not working! :-( } if(type == MSG_DESCRIPTION_CHECKDRAGANDDROP) { GePrint(mdd.op->GetName()); //<---Not working! :-( } if(type == MSG_DRAGANDDROP) { GePrint(mdd.op->GetName()); //<---Not working! :-( } return TRUE; }-ScottA

If that is the case, then these might only be sent to a recipient plugin 'object' (checking in its Message() method). That would mean there is no way to handle general drag-and-drop as the op intends.

Thanks, but it's very annoying to can't do it. I hope any devs can give a hand for that. I have developped a custom browser over GeUserArea but i cannot drag&drop; materials from to any where.

i forgot to say, as you know GeUserArea can detect the dropped materials...
this for getting:case BFM_DRAGRECEIVE: { String string, str; LONG type = 0; void \*object = NULL; C4DAtomGoal \*bl = NULL; GetDragObject(msg,&type,&object); if (type==DRAGTYPE_ATOMARRAY && ((AtomArray\* )object)->GetCount()==1 && ((AtomArray\* )object)->GetIndex(0)) { bl = (C4DAtomGoal\* )((AtomArray\* )object)->GetIndex(0); if (bl->IsInstanceOf(Mmaterial)) { str += "Mmaterial"; } } -

^Thanks for posting that code khor.
I didn't have that one in my notes.-ScottA

you're welcome. If it helps i can completed last part as:
case BFM_DRAGRECEIVE: { String string, str; LONG type = 0; void \*object = NULL; C4DAtomGoal \*bl = NULL; GetDragObject(msg,&type,&object); if (type==DRAGTYPE_ATOMARRAY && ((AtomArray\* )object)->GetCount()==1 && ((AtomArray\* )object)->GetIndex(0)) { bl = (C4DAtomGoal\* )((AtomArray\* )object)->GetIndex(0); if (bl->IsInstanceOf(Mmaterial)) { str += "Mmaterial"; } } else str = str+"unknown object"; if (msg.GetLong(BFM_DRAG_FINISHED)) info("Dropped..."+str); return SetDragDestination(MOUSE_POINT_HAND); break; } -

Thanks again.
That handles dragging things ** to** the UA nicely.
Now we just need someone to post how to handle dragging from the UA.-ScottA

i found a hacked way for drag from a GeUserArea to another GeUserArea. I'm testing now .
But still really need help for native method -

Hello khor, did you find a solution to start a drag from a User Area? I need to do this as well, and I
have doubts it will be possible from Python if even from C++.

Hi,
I'm not sure I'm getting this right, but in order to start a mouse drag from a GeUserArea you simply call HandleMouseDrag from GeUserArea class.
I don't think the function exists in Python. Or if it does, it's at least undocumented. -

Hi Andreas,
thanks, seems like I missed this method. Maybe I can work around this method missing from
with a C++ Plugin somehow. -

Just verified, HandleMouseDrag is not available in Python.
