How to disable perticular command for custom entity

Anonymous — Wed, 09 Nov 2011 09:27:03 GMT

Hello everyone,

This is my first post so all feedbacks are welcome. I have created a custom entity derived from AdDbEntity and I want some commands (such as "explode") not to work on the custom entity (Disabled). Is this possible? If yes how?

Thanks in Advance.

Just return an error code from your entity's subExplode() implementation.

Owen,

Thanks for suggestion. I have already considered that, but I need to block a couple of commands such as "Explode", "trim" etc. Therefore I was looking for something general and globally applicable. Is it possible to override the functionality of commands for perticular objects (custom entity).

And can you please also tell the GroupName of EXPLODE command. Or where I can get this type of information?

Thanks for your reply.

In general, it is impossible to prohibit AutoCAD commands to work on custom entity from DBX-module. This can be done in the ARX-module using reactors (such as AcEdInputContextReactor, AcEdSSGetFilter, AcEditorReactor, etc.)

Thanks for suggestion. Can you please be more specific and if possible give me some code snippet. Basically I need to prevent those actions on custom entity and using reactors all we get is a notification, not control to bypass command. Is there something to do the same.

Thanks.

This is simple sample.

Array of disabled command and array of checked classes defined in function Initialize:

void Initialize()
{
  commands.append(_T("MOVE"));
  commands.append(_T("TRIM"));
  commands.append(_T("EXPLODE"));
  commands.append(_T("LENGTHEN"));
  classNames.append(AcDbLine::desc());
  classNames.append(AcDbCircle::desc());
  classNames.append(AcDbArc::desc());
}
