In wayland, I have found wl_data_device which I suppose should do the similar thing. The question is, since there is only one wl_data_device::selection event, is it possible to get current selected data as well as clipboard content in wayland (or in another word is it possible to have X11's handy middle button paste)? I also found the only weston client that uses clipboard (weston-terminal) use it in a weird way, should this be considered a bug and should the selection signal used in a similar way as the XFixes signal in X to monitor clibpoard/selection changes? </blockquote><div> It is understood that the client or toolkit should implement this if it wants to support such a feature. - Scott </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Thanks.
