set off a layer

[leonimas]

Hi to all,

I want to set off a layer; I've writted the following code (autocad 2012):

err = pLayerTable->getAt(_T("TEXT_DESCR"), layerId);
if(err != Acad::eOk)
{
    MessageBox(acadHandle, acadErrorStatusText(err), _T("Titolo"), MB_ICONERROR);
    return;
}
acdbOpenObject(pLayerTableRecord, layerId, AcDb::kForWrite);
pLayerTableRecord->setIsOff(Adesk::kTrue);
pLayerTableRecord->close();
pLayerTable->close();

but the "bulb lamp" icon of the TEXT_DESCR layer, keeps the same yellow state ...

How to simulate (with objectarx) the _LAYOFF command ?

Best Regards

Leonard

Your thread title is misleading, as your question is actually about how to trigger an update of the UI to reflect your programmatic changes. I don't know the answer offhand, but fixing your title may attract more attention. BTW, your code snippet fails to close the layer table in the err != Acad::eOk case.

Sorry,

I expressed myself badly ... the title it's ok, I want to disappear a graphic

entity of a block, and this entity is drawn with the layer "TEXT_DESCR".

If I use the 'setIsOff()' function the entity doesn't disappear ...

Thanks

Try ads_regen() to update the display.

I've tried acedUpdateDisplay() but nothing ...

ads_regen() where is ? VS2010 doesn't find this function ...

[owenwengerd]

Here is the declaration:

void ads_regen(void);

[leonimas]

ads_regen() doesn't works ... 😞

In what context is your code executing? Test it in a standard command function to determine whether context affects your results.

Hi,

the code is the following (inside an  autocad command):

static void ASTSIced_ICEDInsert () {

            ....

            err = pDwgDb->getLayerTable(pLayerTable, AcDb::kForRead);
            if(err != Acad::eOk)
            {
                MessageBox(acadHandle, acadErrorStatusText(err), _T("Title"), MB_ICONERROR);
                return;
            }
            if (pLayerTable->has(_T("TEXT_DESCR")))
            {
                err = pLayerTable->getAt(_T("TEXT_DESCR"), layerId);
                if(err != Acad::eOk)
                {
                    MessageBox(acadHandle, acadErrorStatusText(err), _T("Titolo"), MB_ICONERROR);
                    pLayerTable->close();
                    return;
                }
                acdbOpenObject(pLayerTableRecord, layerId, AcDb::kForWrite);
                

                pLayerTableRecord->setIsOff(Adesk::kTrue);
                pLayerTableRecord->close();

                //acedUpdateDisplay();
                //ads_regen();
            }
            pLayerTable->close()

            ....

}

ACED_ARXCOMMAND_ENTRY_AUTO(CIcedApp, ASTSIced, _ICEDInsert, ICEDInsert, ACRX_CMD_MODAL, NULL);

Some things to try:

1) Does a manual _REGEN at the command prompt (after running your command) update the display as you expect? If not, then maybe the problem is your expectations instead of the code.

2) If you are targeting a specific block, perhaps opening all block references of that block and calling recordGraphicsModified() will trigger an update.
