More Copying Issues - prevent copying to another document?

Kyudos — Tue, 21 Feb 2017 22:42:08 GMT

I like being able to Ctrl+C / Ctrl+V my custom objects within a document, but pasting them into a different document has some underlying data merging problems I don't have time to solve just yet. So, is there a way to prevent my objects from being copied to another document without disabling Ctrl+C / Ctrl+V?

In a similar vein, can I keep my objects out of a WBLOCK command?

I suspect I'll have to disable wblock cloning and kill off copy/paste - but is there another way?

Ok - so I had a go at disabling wblockclone for my objects. However, despite what the docs say, subWblockClone never gets called. All copy functions go through deep clone.

I can crudely veto in documentLockModeChanged, but when is subWblockClone supposed to come into effect?

Further - I can veto WBLOCK in PICKFIRST mode, and I can detect selection of my objects in endSSGet in not PICKFIRST mode. But after selecting from the WBLOCK dialog, Autocad returns to the WBLOCK dialog. How do I cancel the command? And what about WBLOCK of the whole drawing? How do I stop that?

I've tried various ways in AcEditorReactor::beginWblock to try and cancel out of the command but it seems impossible to stop.

So I'm left hoping there is a simpler way to stop my objects taking part in WBLOCK.

Should I just do nothing in the wblock filer?

Anyone?

Hi,

Can you please try implementing AcRxEventReactor::beginWblockObjects , which gives an access to preset mapper, you can skip the objects from IdMapper to prevent from cloning.

In this blog I discussed about mapping relation during CopyPaste:

@moogalm

I'd like to remember about case 11923088 related to Copy/Paste mapping algorithm.

Thanks for the reply. Until I have time to look deeper into this, I simply set some flags when COPYCLIP starts that allows me to veto PASTECLIP to a different document. Of course that won't help pasting between instances of ACAD.

What would you recommend in that situation? Is it possible to have Ctrl+C / Ctrl+V within a document, but disallow pasting in another instance? This is why I was trying to manipulate the clipboard (see my other posts). Ideally I'd like to know the source of the data on the clipboard at pasting time...

Hi sorry about that,

@Alexander.Rivilis found a issue with the code, until further investigation I have made blog to private mode.

Anyway you can have a look the code structure.

using namespace std;

static void closeOrDeleteDbObj(AcDbObject *pObj)
{ if (pObj->objectId().isNull()) delete pObj; else pObj->close(); }

template <class T> struct unique_db_ptr : public unique_ptr<T, void(*)(AcDbObject*)>
{ unique_db_ptr<T>(T*& t) : unique_ptr<T,void(*)(AcDbObject*)>(t, closeOrDeleteDbObj) { } };


static AcDbObjectId addToDb(AcDbEntity *pEnt, AcDbDatabase *pDb = nullptr)
{
    AcDbObjectId newEntId;

    if (nullptr == pEnt)
        return newEntId;
    if (nullptr == pDb)
        pDb = acdbHostApplicationServices()->workingDatabase();
    if (nullptr == pDb)
        return newEntId;

    unique_db_ptr<AcDbEntity> ent(pEnt);
    AcDbBlockTable *pBt;
    if (eOk != pDb->getBlockTable(pBt, kForRead))
        return newEntId;
    
    unique_db_ptr<AcDbBlockTable> bt(pBt);
    AcDbBlockTableRecord *pMs;
    if (eOk == pBt->getAt(ACDB_MODEL_SPACE, pMs, kForWrite))
        unique_db_ptr<AcDbBlockTableRecord>(pMs)->appendAcDbEntity(newEntId, pEnt);

    return newEntId;
}
