Hi
Yes, we have regression tests for graphics.
In general, but especially for core R code, I would rather have
confidence that a fix has not broken existing behaviour before I commit it.
I cannot argue with the point that we could respond to some bug reports
faster.

Hi Paul,
Thanks for keeping me posted and letting me know what I should do.
Are there regression tests for other graphics functions in R? To me
that sounds a bit unnecessary. I think you get more testing from
people who use R; and having a good turnaround for applying patches
(some have been waiting 5 years) would invite better participation.
Thank you,
Frederick

Hi
Just taking a bit more of a look at this today (currently fixated on making
sure I can build some good regression tests).
The best thing you can do is to keep reminding me like this :)

Hi Paul,
Thanks for your efforts. Do you have an idea when my patch(es) might
be committed? Is there anything I can do to help move this along?
Thanks,

Hi
The current status is that I am keen for people to contribute some testing
code (see https://bugs.r-project.org/bugzilla/show_bug.cgi?id=16951)
There were also some getGraphicsEvent() changes/fixes suggested by Richard
Bodewits (cc'ed), for which I am also seeking test code.

Hi Paul,
Just checking in to see what the status is.
From my perspective it seems logical to split off X11 into a separate
package, so development can proceed at a reasonable rate, but I
haven't yet tried to see if that's even possible.
Thanks,
Frederick

Hi
Taking a look at those patches is now on my todo list, so I may be in touch
with both of you at some point to request some testing.

Dear Daniel Greenidge,
To enable getGraphicsEvent on Cairo, you have two patches to choose
from:
https://bugs.r-project.org/bugzilla/show_bug.cgi?id=14364
https://bugs.r-project.org/bugzilla/show_bug.cgi?id=16951
The second one is by me, and the first one is from five years ago by
Hugo Mildenberger.
Both patches are very simple, they move some lines enabling
getGrahpicsEvent outside of a if(!cairo) statement. My patch also adds
the ability to execute code (e.g. for animation) while the interface
is idle.
Top guy Duncan Murdoch has expressed that he doesn't have time to work
on applying these patches, and I haven't had any responses from the
rest of the R Core Team. I was thinking that perhaps your best bet is
to try to create a package called e.g. "X11-fixes" which people can
use to get a better X11 library (there is also a bug waiting to be
fixed from 2001:
https://bugs.r-project.org/bugzilla/show_bug.cgi?id=16702).
I don't know if CRAN would accept such a package, or if you'd have to
distribute it via GitHub, but R has excellent tools to facilitate the
distribution of code via packages. Whether the R kernel exports enough
functions to allow a package to take over event handling, I'm not
sure. I was intending to look more into the details of this
possibility but haven't had time.
Best wishes,
Frederick

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
