Hi all, I'm writing an interactive plotting function for viewing fMRI datasets. Currently, I get keypresses using grDevices::getGraphicsEvent().
Unfortunately getGraphicsEvent() only supports the X11(type="Xlib") graphics device on Unix systems. The Xlib device doesn't support buffering (i.e. dev.hold() and dev.flush()), so redrawing the plots causes lots of flickering. Is there a way to get keypresses while using the cairo graphics device? Alternatively, is there a way to prevent flickering with the Xlib graphics device? Best, Daniel Greenidge ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
