Subject: getGraphicsEvent() alternative for cairo graphics device?
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
