I think i checked in a change to the a2dZoomTool:
a2dGetCmdh()->Submit( new a2dCommand_Zoom(
a2dCommand_Zoom::Args().what( a2dCommand_Zoom::Zoom ).x1(x1).y1(y1).
x2(x1+rec->GetWidth()).
y2(y1+rec->GetHeight()).upp( false ) ) );
instead of:
//GetDrawer2D()->SetMappingWidthHeight(x1,y1,
fabs(rec->GetWidth()),fabs(rec->GetHeight()));
This makes it a command, and that generates an event. wxEVT_DO.
A problem is that i think zooming should not be part of the undo chain.
Undo should just undo changes to the document.
