TkHTML progress, additional questions


#1

Progress:

I finally made some progress setting up TkHTML and getting it to run
both as a
Ruby script and within irb. (The most basic thing I have to do is start
irb
(or Ruby) with prefixes like:

LD_LIBRARY_PATH=/usr/local/ActiveTcl/lib:$LD_LIBRARY_PATH
/usr/local/bin/irb
(or ruby)

Somebody had told me that before, but it didn’t seem to work before (I
just
did a reinstall, so maybe that is the difference). (And, unfortunately,
I’ll
have to do another reinstall in the “near” future (maybe not for a few
weeks)
because once again, readline did not get compiled in (but that was
because I
had renamed readline.h a week or so ago to do some experimentation and
forgot
to rename it back.)

Minor point (for me) to remember–some of the examples I tried did not
include
the Tk.mainloop statement–worked much better after I added that :wink:

Questions:

  1. Fonts: The fonts don’t look too good–I presume that when I learn
    more
    about TkHTML, I’ll find a way to change the fonts, maybe not by the
    user, but
    hopefully within Ruby? (I’m hoping not to have to fool around in C,
    C++, tcl
    or whatever to change fonts.)

  2. Background: When I run either hv.rb or ss.rb, I get a nice white
    background (i.e., this is what I want). When I run (this) sample
    program
    within irb:

require ‘tk’
require ‘tkextlib/tkHTML’
doc = “<body bgcolor=”#FFFFFF"><FONT SIZE=“3” COLOR="#000000"
FACE=“Courier,serif”>It is worth"
hv = Tk::HTML_Widget.new.pack
hv.parse(doc)
Tk.mainloop

I get a gray background, which I don’t want. I presume I’ll find a way
to
change this to white as well, hopefully within ruby (or maybe my HTML is
totally wrong (which wouldn’t surprise me))?

  1. Full Screen mode:

When I run ss.rb and switch to full screen mode on my dual head machine,
the
widget expands to fully cover both “heads”.

Furthermore, I can’t find a way to get of full screen mode except by
switching
to a VT, then finding and killing the process. (I’ve tried f,f
and
some other things I could think of.) Is there another way?

Note: These points about full screen mode are probably not a big
issue–I’ll
probably just disable full screen mode on the ss.rb menu (if I use
anything
like ss.rb).
