Wow. Look what SWIG does to GetTextExtent in Grid.cpp: void SwigDirector_wxGrid::GetTextExtent(wxString const &string, int *x, int *y, int *descent, int *externalLeading, wxFont const *font) const { ... if (swig_get_up()) { wxWindow::GetTextExtent(string,x,y,descent,externalLeading,font); return; } obj0 = rb_str_new2((const char *)(&string)->mb_str());

We need to use directorout typemaps, rather than just plain "out". I inserted this, and it seemed to work: %typemap(directorout) wxString { $result = wxString(STR2CSTR($1), wxConvUTF8); } Typemaps are sure a confusing feature. They''re great, and powerful. But I hope for SWIG v3 they can be completely ov...

(Mostly for Roy): I saw this on the SWIG list, and wonder if it might be related to the problems we have been seeing where multi-arg typemaps end up invoking the wrong wrapper methods. (Not the newly-discovered directorout stuff). Perhaps if we switched to "compactdefaultargs" things would start to work more sanely. Looking at this section of the SWIG docs, it looks like it should be safe, and might at least make it easier to diagnose any problems, if it doesn''t fix them outright: http://www...

Hello guys, Alright Alex..... I need a few tips on where to start. I know that I''m going to need to rewrite the wxSocket header files, in order to incorperate them into wxRuby. But some advice on stuff such as wxSocketClient::new/connect, where it takes a wxIPAddress, and so forth. I know they are pretty friviolous structures for holding information about Addresses in which to make

Attached are patches to make the textctrl.rb sample work fully. Note the new %directorargout typemap I added to fix wxWindows calling into SWIG. I don''t know if this can fix all such problems or not. Let me know what you think. I also rubified the sample a little bit more. Also, note that I fix the << operator so the function can be called. I hope I did this right. Roy

...It''s entirely possible I just misunderstand something about the way this is supposed to work but I''ve pored over the help files many times. Interestingly, if you change -ruby to -python then it appears to correctly generate the code for obj1. You may also want to look at my directorout typemap I''ve included which tries to get the results from the Ruby call so it can pass them back to the returning function if called from C++. I believe I''ve done that part correctly but I''m always happy to be educated if I''ve done this the hard/wrong way R...

Swig is making mincemeat out of ComboBox.new. Because of the way it''s picking the ''correct'' one to call it''s calling with a null name instead of a default name. How did we fix this before?
