I'm using gtk2 in unicode w/ wxWidgets CVS head.

1) Unicode fix, add wxT(""), cancom.cpp line 48
wxlMoveObjectCmd::wxlMoveObjectCmd( wxlCanObj* object, double x, double y )
    :wxCommand( true, wxT("drag object") )

2) In gtk2 I get an invalid bitmap assert in wxlCan

in canslm.cpp
MyFrame::MyFrame( wxWindow *parent, wxWindowID id, const wxString &title,
...
    // give it some initial size to make it happy
    mainCan =3D m_canvas =3D new wxlCan( this, wxID_ANY, wxPoint(0,0),
wxSize(10,10) );
...
   // else this code asserts when it tries to use wxlCan::m_bitmap
    m_canvas->SetYaxis( false ); //true );

    //defines the minimum x and y to show and the number of world
units per pixel in x and y
    m_canvas->SetMappingUpp( m_xOrigin, m_yOrigin, m_xScale, m_yScale );

It works well for me after regenerating the bindings (I removed the
wx_XXX stuff), I haven't tested everything though or look too much at
the code. I've attached my Makefile (using wx-config) and an updated
wxlcan.rules.in file that uses simpler paths, just "." will suffice
since you want them in the current dir anyway. See also the genwxbind
tag in the Makefile, eg "$make genwxbind" to generate them.

It looks really great, no flicker at all!

Let me know if things work for you now, I'll try my best to try it
again in windows tomorrow. I just got a newer (but still old) machine
that seems a little flaky, but I managed to get VC Express 2005 on it.
