Hi Alan,
Nice work. I’ve been doing something very similar
indeed. Maybe everyone who looks at the TextView and
the TextBuffer thinks that there has got to be an
easier way.
Once you’ve figured them out it’s a very powerful
interface but getting to that point is frustrating.
There are actually lots of things in Gtk like that.
I’ve been thinking about a ‘sugar’ library for
RubyGnome, like the sugar for wxruby or the old EzGtk.
Only EzGtk is too much, so how about less of a wrapper
for the entire library and more like a set of
extension methods for each widget (like the text-only
combobox interface). Making the default case easier,
without hiding the rich interface.
I suspect that wrapping RubyGnome has come up a lot on
the list over the last few years, but there doesn’t
seem to be a simple set of helpful extension methods
around. Want to start one?
best,
Dan
Hi Chris,
Thanks for your encouragement.
EditView is still in active development.� Since I
wrote to you, I’vemade it into a widget.� (I don’t
think that the file I gave you reallyqualifies as a
widget.)� I’ve been struggling with events, so
anythingI give you probably has some code that doesn’t
work.� I’m specificallyreferring to
current_line_length.� I called it from
asignal_connect(key_release_event) and
asignal_connect(button_release_event).� The reason
was that� my user islimited on how long each line
can be and wants feedback on how long herline is as
she adds characters.� This function worked for that
purpose,but somehow began a text selection that I
don’t want and can’t turnoff.� It also disabled
buttons in the same window by intercepting theclick on
the button.� I’m trying another approach that is not
aselegant, but may be easier to implement.� (What I
think I need is to beable to add functionality to
these events, without overriding thecurrent
functionality.)
Suggestion.� If it lacks some facility that you
need, let me know.� Imay have added it or I may be
able to add it easily.� I have a thirdfile that is a
textual cut and paste from the documentation.� As
youcan see, when I take a method from the underlying
classes, I copy thedocumentation into the RDoc format,
so that (1) I’ll be able togenerate complete
documentation for EditView and (2) I’ll be able toadd
notes and examples to documentation that I regard as
inadequate.�Any method that doesn’t exist in the
underlying classes, such as "find"references only
methods that I have brought into EditView.� This
way,no one need shuffle through many pages to figure
out what’s going on.
The listings are long enough that the catch the
attention of thislist’s moderator.� I’m not certain
of the best way to give you updatedlistings.�
Perhaps someone can clue me in.� (I also don’t know
if thereare others who can benefit from this effort.)

I started down the same path that you are, but had
problems related toglade. I decided to not use glade.
I had a terrible time with the GTKhierarchy and
trying to find out what was what. I ended up by
creatinga widget, EditView, that wraps the different
related GTK classes. Ihave not included everything in
these classes, but I’m adding the thingsthat I need as
I need them. I’m attaching it, along with a program
thatdemonstrates its use. HTHChris Rohlf wrote:

GtkTextView called ‘textview’. Which has several

to control the text withinthat textview using
libpango, Preferably using the libpango

usinghttp://ruby-gnome2.sourceforge.jp/hiki.cgi?pango-markupi
have played around in on_open_file() within the text

cant display it correctly.Any ideas on how i can
achieve
this?Thanks!Chris-------------------------------------------------------------------------This
