Move/drag event

Hello!

I need to get move/drag operation beg and end coords. Couldn't find a way to get drag event or initialize drag. Any ideas ?

There are example add-ons bundled with the API to illustrate the use of many calls. For drag-drop operations, I suggest looking at Navigator_Test and searching for DGDragDropMsgData. You should find all the details your looking for in that data structure.

In navigator_test i can get drag operation in list view, didn't found what could suit me. I need to get move/drag operation when moving object and retrieve beg and end coords.

ACAPI_Notify_GetTranParams could be the one, but ..

*The transformation data is valid only between a APINotifyElement_BeginEvents and the following APINotifyElement_EndEvents notification.

..i don't know how to get these events.

EDIT: Hmmm... i might have found a way, will set up for a try.

Sorry, I misunderstood your question – I thought you meant drag-drop in the UI, e.g. list items. What you really want to do is track moving elements.

In order to get events for an element moving, you need to instruct ARCHICAD to notify you by calling ACAPI_Notify_InstallElementObserver. You also need to identify which elements should trigger a notification with ACAPI_Element_AttachObserver.

Thanks Ralph!

Got it working.

If i could initiate move/drag operation in project would be even better, but i guess there isn't structure for that.
