Well, I agree with you, that should be working, but it doesn't. I tried
in the single sample under the editor samples, and didn't. Just the same
but sometimes I get a "Segmentation fault" but some other there is no
error but the code doesn't do what it's expected to... I tried with the
a2command_FileSave and a2dCommand_FileSaveAs with the same results as above.
I was trying to get it working with the other way as you suggest, but
there I got another problem, my code is the following:
a2dIOHandlerStrOut *hdl = new a2dIOHandlerStrOut();
m_canvas->GetCanvasDocument()->Save(wxT("test"),hdl);
I got a compiler error because the a2dIOHandlerStrOut has some pure
virtual method, this are:
virtual bool a2dIOHandlerStrOut::CanSave(const wxObject*)
virtual bool a2dIOHandlerStrOut::Save(a2dDocumentOutputStream&,
const wxObject*)
So, in order to get this class working I suppose I have to create a
derived class and put this method to do something, but i cannot figure
out what?.
I appreciate all your help. Or another alternative to get this working.

For this, when I load the saved examples in to the canvas it works just
good.
My problem is when I do some modification in a drawing and the save it,
until here the program works fine, I can see the xml output, bu then
when I try to load my saved draw the program freeze and doesn't respond
anymore.
Hope this help, so we can improve the great wxArt2d library and help
you debugging.
