Is there the line "#define FL_SHADOW_LABEL ..." in your Enumeration.H?

I notice that commenting out "NUMCONST(SHADOW_LABEL);" in flenum.cc clears
up this missing symbol.  But presumably has other undesired side-effects.

Hi,

Just built and installed fltk 1.1.0b12 and CVS ruby-fltk.

Attempting to run the ruby-fltk samples yields:

[steve@tim samples]$ ruby sample1.rb
ruby: error while loading shared libraries: /usr/lib/ruby/1.6/i586-linux-gnu/rubyfltk.so: undefined symbol: define_FL_SHADOW_LABEL__Fv

Any suggestions?

Thanks,

I've not fully implement methods yet. In next release,
I will provide some methods you want to use.

Hello,

I have tried to understand the fltk doc on TextEditor, 
but with no good results.
In the following example the commented lines do not work, 
as I get "undefined method".
A lot of others methods in TextEditor and TextBuffer
have the same behaviour. Am I doing a silly mistake?
Are these methods not supported? If they are not, how could I
let the user select part of the text and choose a different 
color/size/font for it?

Thanks for the help.

[ruby-fltk-users] Improved editor?

[cix <mc...@gm...>]

Hello,

I am writing an application that should let the user insert
text in a text editor. The one given as example with ruby-fltk 
is almost OK for my needs. I would like to add the possibility
to use different colors and/or font inside the text area in order to 
highlight part of the text. It seems to me that that is possible using 
TextEditor instead of MultilineInput, but I guess, from ruby-fltk
docs, that TextEditor is not really supported/implemented.

I have also thought to use the helpview associated with a small 
html editor, but it seems that helpview is a readonly widget.

Does anybody know how I could achieve my target?

Thanks,

Dear all,

I've released the Ruby/FLTK v0.7.0. Major changes are as follows:

* New classes:
  - BMPImage, GIFImage, Wizard
  - FLTK::Thread (defined in fltk/thread.rb)
    I recommend you to use this thread inside event handler and callbacks.
* New fltk-xunicode specific methods:
  FLTK.set_charcode(code), FLTK.set_internal_charcode(code)
  In case that you use these methods, you should check they are defined.

I'm not sure what is a correct way to show a buffer text.
I think we should call show_insert_position() in handle().
In the following example, TextDisplay shows its buffer text
when handling an event FOCUS.

=== example.rb ==
require 'fltk'

class MyTextDisplay < FLTK::TextDisplay
  def handle(e)
    case e
    when FLTK::FOCUS
      show_insert_position()
      return true
    else
      return false
    end
  end
end

w = FLTK::Window.new(0,0,200,200){
  d = MyTextDisplay.new(200,200)
  b = FLTK::TextBuffer.new(100)
  b.text = "this is a buffer text."
  d.buffer = b
  d.insert_position(0)
}
w.show

Hello,
I made ruby-fltk-0.1 on netbsd v1.5 with the command

ruby extconf.rb --disable-gl
--with-fltk-include=/home/omura/pub/fltk-1.1.0b10 \
 --with-fltk-lib=/home/omura/pub/fltk-1.1.0b10/lib

This compiled each file like this one, for example:

c++ -fPIC -g -O2 -pipe -I/usr/local/lib/ruby/1.6/i386-netbsdelf1.5 -I.
-I/usr/local/include -DHAVE_FL_FL_H   -I/home/omura/pub/fltk-1.1.0b10

And linked like this:

gcc -shared -L/home/omura/pub/fltk-1.1.0b10/lib
-L/usr/local/lib/ruby/1.6/i386-netbsdelf1.5 -L/usr/local/lib

Then when I try to run ruby sample1.rb I get:

This is correct. The event is sent to the Container group,
which is responsible for sending it to the appropriate
child. The code that does that is in FLTK itself.

So the simple fix in this case is to replace the 'return
false' at the end of your Container#handle method with a
line that just says:

  return super(e)

See the section "Handling Events" of FLTK's manual.
The Group#handle(e) (or super(e) in Container#handle()) is
propagates the event to children widgets.
So this means the event is not sent directly to children
widgets, I think.

[ruby-fltk-users] Event propagation Group => Widget

[cix <mc...@gm...>]

Hi,

I am using fltk/ruby for two o three weeks now, but I still have some 
problems.
I wrote a small example which reproduce the condition I don't understand.

I have a Group (Container) containing a Widget (Contained).
It should be a square containing a label/button.
The Group handle "hides" the Widget' one, so that I never reach 
Contained::handle(e) if not removing Container::handle(e).
I don't know how to solve the problem. Did I miss somehing?

If  you have time, there is a minor problem explained in the comment of the 
initializer of "Contained".

Thanks!

I will define an alias 'widget_color' of Widget#color().

You can also define an alias by yourself like this:

class MyBrowser < FLTK::Browser_
  alias widget_color color  # should be defined before Drawable
  include FLTK::Drawable

Now you can use widget_color.

  b = MyBrowser.new(5,5,90,90,items)
  b.widget_color(FLTK::RED)
