Hi Matthijs, Yes, when it has `introspectable="0"` then you can't call it using GIR bindings from JS. I found it useful to generate the documentation for Mutter from the gir - see this (you need g-ir-doc-tool) [0[ What do you want the xwindow for? Back when I wrote the Maximus extension (quite out of date now) I needed to get the X ID of the window so I could undecorate it and neither the X ID or the undecoration were exposed in the Mutter bindings, so I ended up forking out to xwininfo/xprop to do the job [1]. Depending on what you need the xwindow for, perhaps xwininfo/xprop could work for you.
Also if you have the wnck gir there are a bunch of methods exposed there that are not exposed in Mutter (for example at the time of writing the Window Options extension[2], also very out of date, the always_on_top ability was exposed in Wnck but not in Mutter: it was exposed in Mutter from 3.6 onwards though), so perhaps that could be another way to do what you want. You can find wnck documentation here[3] [0]: http://worldofgnome.org/how-to-generate-native-gjs-docs/ [1]: https://bitbucket.org/mathematicalcoffee/maximus-gnome-shell-extension/src/e0ee4366f832b7b26a269ce7183df457602f4ff9/maxi...@mathematical.coffee.gmail.com/extension.js?at=default#cl-162 [2]: https://bitbucket.org/mathematicalcoffee/window-options-gnome-shell-extension/src/ba352408fbd05b51b1b25e95e2e6edc1159cb961/window-opti...@mathematical.coffee.gmail.com/extension.js?at=default [3]: https://developer.gnome.org/libwnck/stable/ cheers Amy On 29 September 2014 21:21, Matthijs Kooijman <matth...@stdin.nl> wrote: > Hey folks, > > after digging around with extension js code for a while, I found > that a lot of the native API is "documented" in gir files.
