Re: [Vala] Compilation error using XClientMessageEvent

[Axel FILMORE <axel filmore gmail com>]

Well, no, currently I can't get it to compile, this sample code is from an
implementation of the system tray specification :
http://standards.freedesktop.org/systemtray-spec/systemtray-spec-latest.html

There's other implementations in plain C but I'd prefer to have it in Vala,
that's cleaner that mixing C and Vala.

I think that code worked before maybe with another version of the compiler
or with a modified vapi file, I don't know.

:)
