Thanks for your detailed report. Function argument hints were recently fixed to use the system-wide settings for tooltip foreground and background colors. Thus, I suspect the problem is in a bad setting for tooltip colors. Go to the KDE system settings (should be available by running 'systemsettings' in a console), open page Common Appearance and Behavior->Application Appearance->Colors->Colors, and check the settings for Tooltip Background / Text.

Please let us know, whether these match or do not match the color of the argument hints in RKWard.

Regards
Thomas

Thanks for the reply. I checked systemsettings. The colors do not match. MAy be it is not pulling the colors from the KDE settings. However I am running Rkward on Ubuntru with Gnome/Unity. Can this be causing the problem?

Possibly. Could you please check, whether this appears to be the same issue (thread includes a workaround):
http://ubuntuforums.org/showthread.php?p=9879841&posted=1#post9879841

In case that is not it: What about other tooltips? E.g. the ones in the "Workspace" window. Do these display correctly?

It does not seem to be the same problem as tooltips in other KDE applications work fine.(I tried Kate). I tried the workaround and it did not help. The tooltips in workspace window work fine. Its only function hints in Console and Editor that are not working.

Ok, thanks.

One more follow-up question: Have you been using RKWard before version 0.5.7? If so, did you experience this problem, earlier?

Regards
Thomas

Yes, I have been using rkward before. This problem started after upgrading to Ubuntu 11.10 and rkward 0.5.7

[Thomas Friedrichsmeier]

Hm. I just don't get it.

Do you recall which colors the function argument hints had before the upgrade?

If you are _not_ yet using R 2.14.0, could you try downgrading RKWard to 0.5.6 for a minute, in order to test whether the problem was introduced with RKWard 0.5.7, or with some other update in Ubuntu 11.10.

Anyway, I have also tried another thing in SVN. Could you please test whether that helps (should be available in our daily builds _tomorrow_: https://launchpad.net/~rkward-devel/+archive/rkward-dailys\)

Thanks!

I downgraded to R 2.13 and rkward 0.5.6. The function argument hints are now readable (black on yellow background). I am attaching a screenshot of rkward 0.5.6. I will try the daily build later today.
And one more thing just to clarify, the function/variable code-completion were always readable. Only the function argument hints were unreadable.
Thanks

Hi!

Did you get a chance to test, whether the issue is fixed in the development version / daily builds, yet?

Thanks!
Thomas

RKWard SVN version (to become 0.6.1) has another fix for this. Let's hope it finally puts an end to this bug, for good.
