I was investigating why the find dialog causes an error when you close it. It seems that wxRuby2 is returning a new ruby object when you call Event.get_dialog. This causes some big problems when you''re expecting you''re going to get back the same ruby pointer that you put in. In a brief check over the source I don''t see anything that preserves the original ruby

Have tracked down a fairly serious cause of memory leakage in wxRuby2. swig/fixdeleting.rb adds a hash mapping from pointer address to ruby VALUE in every director initialiser using GcMapPtrToValue. The problem is that being a value in this global hash means that every Wx::Bitmap (for example, and others) are always marked in ruby''s GC mark phase, so they are never collected until shut down, even if they have fallen out of scope everywhere else. I think the way to go is to dispe...

The latest cvs version of SWIG breaks a few things. I have patched common.i to fix most of it. There will be some other things later that should be compatible with all versions. Can someone test to see if this compiles with the old version? Roy -------------- next part -------------- An embedded and charset-unspecified text was scrubbed... Name: common.i.patch Url:
