How to check unsaved changes?

Anonymous — Thu, 03 Aug 2023 15:15:50 GMT

I open some project in ArchiCAD. Modify it, but not save.
Than I open another project using my Add-On.

In this case I lost all my changes in first project.
How I can check unsaved changes in project? Or may be open a new project with checking unsaved changes automatically? Thanks

Just for more information: did you open the new project using the automate function APIDo_OpenID?

Yeah, I don't see an event handler function in a quick search, nor any type of state test.

I searched for 'dirty', since a 'dirty flag' is a pretty standard term to tag a file that has been modified. No go. Searched for 'changed' and 'modified', and only came up with handlers for dialog items.

Ralph? 😉

Hi, Karl

Yes, I open the new project using the automate function APIDo_OpenID.

No, sorry. You could attempt to track the user editing elements. but that's no guarantee.

I understand, Ralph, thanks a lot!
It's inconveniently, but I will try to ask user check unsaved changes.

Excuse me, Ralph. Can you advise functions for track the user editing elements and may be some another changes? Thanks

Take a look at ACAPI_Notify_InstallElementObserver

I'm use example from docs for API 12.

First, it's not compiled for API 12. For example, API_NotifyElementType does not have 'typeID' field. But, so it is not important as

Second, I could not to catch any events. I just try to show message box when any event occur, but nothing happen when I add new element, move, copy or delete.

May be I must register event types?

Thanks

Yes, you do (element editing and element creation). It would pay to read the entire Notification Manager section to understand how this works. Note ACAPI_Notify_CatchNewElement to monitor the creation of new elements.
