The reason we have troubles with this, is cause the Ruby Installer project just went from MSVCRT compiler to the MINGW compiler. Different compilers have different methods in which to compile code, and export Library Routines, so binary extensions built for MSVCRT, isn't compatible with MINGW. The same holds true on Ubuntu systems. Ubuntu version 8.10 and before earlier use gcc 3.3, which is incompatible with Ubuntu version 9.04 onwards, which uses gcc 4.0. We have to use different builds for < 8.10 compared to > 9.04. The main cause of this, is RubyGems isn't very compiler aware, outside of the main compiler names, they don't allow for Compiler versions in the naming scheme. So we have to package things a bit differently. In most cases, when you try to install a binary Gem, it won't follow the compiler used, especially MINGW, as it just recently became popular with the adaptation of the Ruby One Click Installer project. You will find with our next wxRuby gem release, that it will be compiled for MINGW and GCC 4.0+. And then we'll have to provide deprecated versions for older GCC Versions. I don't know if we will still maintain a MSVCRT version for Windows, as that has not been decided yet. hth, Mario On Thu, Aug 19, 2010 at 11:22 AM, tuti plain wrote: > Hi, > > I tried using Ruby Installer 1.8.6 and now it works (after requiring > rubygems as you suggested).

But Wx::EXPAND (or in C++/xrc, wxExpand) is definitely what you want, as Mario says. The proportion argument controls sizing in the main (in this case horizontal) dimension. Wx::EXPAND means it should fill the space in the other dimension. If that's not working, check that the sizer itself is really getting the space you think it is - have a look at the boundaries in XRC designer - these should be an accurate reflection of what it will look like.

My fault, and it is a perfect example of Satterwhite's Observation on Life #2: "In any situation in which theory conflicts with reality, reality wins hands down." I was basing my reply on the documentation of style TE_RICH: "Use rich text control under Win32, this allows to have more than 64KB of text in the control even under Win9x. This style is ignored under other platforms." That was the theory. You're telling me what the reality is based on experience - that it works well under the other platforms. I should have known better. Thanks much. I'll try this. -- Posted via http://www.ruby-forum.com/.

I?d intended to come up with a small example of the problem, but it turned out to be more difficult than I?d expected. Then vacation and other activities wiped out most of about 7 weeks. I eventually was able to reduce the stack build-up significantly, by avoiding passing the Wx::Event objects and other clean-ups. I also moved my working logic out of all the rescue blocks. I understand that shouldn?t make a difference. I had the impression that it did reduce the stack build-up, but I could very well be mistaken. Perhaps your conjecture--that if the next event hasn't started, the old stack context is still there--is correct. I did not eliminate all of my use of exception handling for non-terminal errors. I use exception handling to improve the program?s performance when checking for those problems ahead of time in my program when I believe that it would be a significant performance hit. I was never able to reproduce any of the remaining stack build-up problems in my simplified example, so I still don?t know what is going on. The stack build-up is slow enough that I?ve never been aware of it interfering with my program?s behavior. Thanks again for all your help.
