Hi all,
Thanks for the tips.
i have verified that this code actually IS running on the main thread, i was
wrong about that in my original message. Here is the situation. WebKit
launches WebKitPluginHost.app and that is the process that runs my NPAPI
plugin. The plugin is called on the main thread, and NSApp is already
initialized. However I can absolutely confirm this bug is happening, I
logged a webkit bug on it, no telling what will happen with that.
i was able to fix this problem in my dialogs (not system dialogs) by just
saving the clicked button in a global and calling abortModal, then i just
return the global & it works perfectly. So Charles, your tip about "write
your own method that wraps stopModalWithCode" is probably the practical way
to fix this. But I can't subclass NSApp (it is already initialized) & I'm
having trouble figuring out how to write a method that can just intercept a
class message in general. Is that possible?
thanks in advance,
bill appleton
