Did it like this, but slightly modified:
target = new (Target); // this is my canvasdocument
target->init(); //adds graphical objects to its root
mCanvas = new a2dCanvas( mLGpanel->mPanel, -1 , wxPoint(0,0),
wxSize(800,600), wxHSCROLL|wxVSCROLL);
mCanvas->SetMappingUpp(-1,-1,0.1,0.1);
mCanvas->SetYaxis( false );
mCanvas->SetScrollMaximum(-5,-4,85,65);
mCanvas->SetScrollStepX(1);
mCanvas->SetScrollStepY(1);
//mCanvas->FixScrollMaximum(true);
//mLGpanel->mViewSizer->Add(mLGpanel, 1, wxGROW|wxALL, 5);
mCanvas->SetCanvasDocument(target);
target->UpdateAllViews();
The graphics is now shown and can be changed dynamically by just changing the
underlying "target" document. It works like charme :).
I think, a2dCanvas is a wxScrolledWindow. Is that right?
Thanks again! now i can play around further ...
Regards,
Thomas
