I've asked this question to support but get no answer, may be in this forum some one could help me.

TsgDXFImage *DXFImg = dynamic_cast<TsgDXFImage *> (FDNavigator->Picture->Graphic);
if (DXFImg) {
DXFImg->SetMatrixMode(smEnabled);
FDNavigator->Update();
}

The compiler is giving an error.
TsgDXFImage::SetMatrixMode is not accessible.

The suppplier of this program is suggesting, in DXFImage.pas to move the methods to public and compile it, pragmatically imposible to compile.

I 've asked this questions and nobody get answered. May be in this forum they can answer.

Thanks

Aby

Hello Aby,

Access to the protected class members in common case is available only from descendants of this class. Delphi has some of such ways which are used in Editor demo. But C++ can't use them. That is why it is necessary to lift a visibility scope of TsgDXFImage::SetMatrixMode property to public, when there is a need to get access to it. We suggest to use the following way:

Code: Select all

class TsgDXFImageAccess : public TsgDXFImage
{
  public:
    __property SetMatrixMode;
};

TsgDXFImageAccess *DXFImg = dynamic_cast<TsgDXFImageAccess *> (FDNavigator->Picture->Graphic);
if (DXFImg) 
{
  DXFImg->SetMatrixMode(smEnabled);
  FDNavigator->Update();
}
