>Summary: FIXED IN SVN: argument prompts are black rectangles

Initial Comment:
Rkward 0.5.4, KDE 4.5.1, Ubuntu maverick 64 bit, R 2.12.0 (2010-10-15).

Argument prompts after the left paren in a function invocation on my setup come up as black rectangles.  They seem to be of varying lengths corresponding to the length of the argument lists, so they may be black on black printing.  I've looked for a way to change font colors or background colors in Rkward, but don't see any way to do it.  This problem is always present; it is not intermittent.  I have not seen it on other kde applications.

Message:
That last bit about the tooltip background color not being respected really
helped to understand what's going on. Thanks. Should now be fixed in SVN /
tomorrow's daily build.

Message:
I found a workaround:  Changing the color for "Tooltip text" in KDE's
SystemSettings > Common Appearance and Behavior > Application Appearance >
Colors > Colors  to a light color makes the argument hints readable.  The
corresponding "Tooltip background" color is not shown as black on this
menu, though, and changing it has no effect on the background color for the
argument hints in Rkward, which remains black no matter how the Tooltip
Text background color is set.

Message:
On my higher-resolution, glossy-screen monitor I noticed that I can just
make out the presence of text on the black rectangle.  The dark gray on
black text is not readable, but it's there.  On my other, non-glossy
monitor no text can be detected.  So it seems this is a problem of the text
and background colors coming out wrong.

Message:
I hadn't realized that the hints could be turned on and off, and they were
off.  Now they're on, and I'm back to the black rectangles.  They appear on
both monitors, and again with both the nvidia proprietary driver or the
default linux driver for the nvidia board.  "str(" produces a short,
single-line black rectangle, while "plot.ts(" produces a multiline
rectangle.

Message:
I can't think of any changes between RKWard 0.5.3 and today that would make
argument hints disappear completely. Except, you can _configure_ argument
hints to be turned off since 0.5.4. Could you please check whether argument
hints are enabled at Settings->Configure RKWard->Script Editor?

Message:
I've downloaded and installed
rkward_0.5.5-0daily-2935-201010252345~maverick1_amd64.deb from the
launchpad repository.  There are still no argument hinting boxes.  I tried
removing the nvidia driver for my GeForce 9500 GT video card, using the
default driver without 3d acceleration instead --- still no hinting boxes. 
I tried using a second monitor, different manufacturer and different screen
geometry --- still no hinting boxes.  One of these same monitors, running
32-bit Debian testing (and therefore R 2.11.1, Rkward 0.5.3 with kde 4.4.5)
displays the hints properly.  And the absence of argument hinting happens
for short and long argument lists, "str(" as well as, e.g. "plot.ts(".

Message:
I won't have time to compile from the SVN for a few days.  In the meantime,
since downloading an update to many parts of  kde 4.5.1 from the ubuntu
repository, the black rectangles no longer appear, but now no argument
hinting at all appears.

Message:
Thanks for reporting.

I don't see this symptom, myself, so I'll need your help in fixing this.
First question: Does this also happen for very short argument hints (e.g
when typing "str ("), or only for longer ones?

I've tried some adjustments in SVN. Could you test those, by either
compiling from SVN (http://p.sf.net/rkward/svn), or by using our daily
builds from https://launchpad.net/~rkward-devel/+archive/rkward-dailys
(wait for the next build, i.e. 2010-10-25 or later)?

Thanks!
Thomas
