This is currently achieved -using a fixed timeout. After requesting conversion of the selection, if no events are received from the X -client which owns the selection for one second, the conversion is assumed to have failed. - -The XWin(1) server should indicate somehow (by placing an atom on the root window?) that it is running with its -internal clipboard integration enabled, and xwinclip should notice this and exit with an appropriate error. - -Probably many other bugs. - -.SH "CONFORMING TO" -ICCCM (Inter-Client Communication Conventions Manual) 2.0 - -.SH AUTHORS -Contributors to xwinclip include Benjamin Riefenstahl, Roland Cassard, Brian Genisio, Colin Harrison, -Harold L Hunt II, Matsuzaki Kensuke, Jon Turney, Chris Twiner and Jeremy Wilkins. |
