Hello, I'm currently updating reactive-banana-wx to use the new wx-0.90 branch and I've encountered a few issues with GHCi support and TextCtrl widgets. GHCi support is currently a mixed blessing on MacOS X. It works the first time but tends to crash when trying to call the start function again. Of course, this is not unexpected, but maybe it's possible to fix it to some extend. I had similar problems when dealing with the OpenAL or the GLFW frameworks, the "solution" was often to simply skip the termination routines. Not pretty, but it works. On that note, the EnableGUI trick is very cumbersome, it would be nicer if this could simply be integrated into wxHaskell, i.e. calling the start function will immediately enable the GUI thing. I can try to look into this. The more important issue is that TextCtrl widgets have changed their behavior: the entry function will now create a multiline widget! To create a single-line text entry widgets, I have to use the textCtrlEx function with flag 0 . This is extremely weird. Also, the latter widget sometimes crashes on me when trying to set the text, but the former doesn't. This is so weird that I can't even tell whether the problem is likely with wxWidgets or with the Haskell bindings. Best regards, Heinrich Apfelmus -- http://apfelmus.nfshost.com |

I'll check it out though. Jeremy |
