Thank you Galen,
I'll give it a try and let you know if it work.

I got errors like this ("no such file to load") running 1.9 Ruby and 
installing the wrong wx.  If you're running 1.9, try this one:

http://rubygems.org/gems/wxruby-ruby19

This whole 1.8/1.9 thing is a huge pain.  Going into the interactive 
ruby and just typing require 'wx' may be a quicker way to work on this 
issue.

The best you can do is to download the gem from rubyforge and install it
with the gem command
(gem install PATH_TO_THE_DOWNLOADED_GEM).

For some reason installing wxruby via gems doesn't work very well (it's
actually very unstable: it either can't find any gems, or installs
version 1.9 of wxRuby).

I see you're using ruby 1.8, so you'll have to grab the package from
http://rubyforge.org/frs/?group_id=35

hope that helps

It installed the gem. I am using ruby 1.8 and when i installed it it 
said:

Looks like RubyMine doesn't use your PATH variable.
Can you try something like this:

- after installing the gem, and adding .gem to your path
(
do:
     export PATH=/home/crystalmoth/.gem/ruby/gems/1.8/gems:$PATH
    export PATH=/home/crystalmoth/.gem/ruby/1.8/bin:$PATH
in the terminal or add these lines to your .profile/.bashrc
)

Can you try running the MainFrame.rb directly from the command line
(that'd be `ruby MainFrame.rb`)

If that works that means you simply need to add the path to your local
gems to RubyMine settings.

Also - what OS are you using? (I'm assuming it's either Linux or OSX)

I tried those lines of path code. It didn't give me any errors, but then
I tried running it from the terminal and got this message:

/usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in
'gem_original_require: no such file to load --Wx (LoadError)
          from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in
'require'
          from MainFrame.rb:4

And I am using Ubuntu Lucid Lynx.

I've attached the custom require file and my code.

Under /usr/lib/Ruby I seem to have the folders 1.8, 1.9, 1.9.0, 1.9.1,
and gems

Could there be a conflict of different versions going on.

Unfortunately it didn't works:

EvtHandler#add_pending_event execute the code asynchronously (usually during
the next event loop iteration) but not in a separate thread.

So my problem is still there: have gui update running on a separate thread.

In one of the archived posts Alex (Fenton) say this:

If using 1.8, you need to manually nudge Ruby's thread scheduler to give
time to the RInotify thread. If using 1.9, this won't be needed, but you
must not call GUI update code in the non-wx thread. GUI updates must be
signalled by posting a Wx::Event to the GUI loop.

As i know processing an event could be done as follow:

- EvtHandler#process_event
- EvtHandler#add_pending_event

Anyone know how to signal a gui event to be processed in a separate thread?

Thank you all,

bio.

...and here's your problem

In the attached example you have

require 'Wx'

and it should be

require 'wx' # lowercase


Once you change it wxRuby will be imported properly, the code won't run 
though (I assume it's a part of a bigger application) - try one of the 
minimal examples from the wxRuby site ( 
http://wxruby.rubyforge.org/wiki/wiki.pl?Getting_Started )

Subject: [wxruby-users] how to reduce size of .exe file got from ocra
Message-ID: <ee2dff048fd4da69b0be1282f36eedf0@ruby-forum.com>

Hi,

I just create a simple WxRuby app and then try to turn it into .exe file
using Ocra. The code is something like...

require 'wx'

class SimpleApp < Wx:App
   def on_init
       Wx::Frame.new(nil, -1, "Simple App").show()
   end
end

SimpleApp.new.main_loop

However, the exe file from Ocra is quite big, about 5.45 Mb. I think it
is because Wx requires many dependencies so that make this result.
BTW, Is there any way to reduce file size of this exe ?

Wut

There should be some freeware out there
to reduce exe file size,
I found two long time ago, but forgot their name

Wut 'sup?

I don't think so, since the 'require 'wx'' line loads all of WxRuby. I
think you'll find that if you write a very elaborate ruby code, along
the lines of 300KB in size, the .exe will not change much.

But if I'm proved otherwise, by all means ignore me.

I believe the exe will be much more than 300 KB in size,
since exe files include all library
it need, and Wx is not a very small one.
about 5 mb is normal

I have used  ruby script2exe before and the result is way bigger than 5 mb
so yours is fine, really

when I do >ocra very_simple_app.rb, then ocra compile and the trace

I think I don't need to load such dependencies like /samples, etc...
I look into ocra document again and found that ocra will load all
dependencies describe in manifest file of the required gem(or source
file). So that I should be able to reduce size by modify the manifest of
my wxruby.

But the problem is, I cannot find the manifest file in the
/lib/ruby/gem/1.8/gems/wxruby-2.0.1-x86-mswin32-60/, cann't find it from
the root of ruby path as well :P

How can I address ?
Any suggestion, pls?

what about move your samples directory somewhere and try again?
perhaps that would do the trick?

Subject: [wxruby-users] evt_button + images_click
Message-ID: <3d4a7dd729f63bfc57b0ba908c822b83@ruby-forum.com>

Hello.

I have two questions.

Here is my code:
---------
require "wx"

class FFF < Wx::Frame
  def initialize
    @b = Array.new
    super(nil, 2, "Bljllll", [5,5], [640,480])
    @mypanel = Wx::Panel.new(self)
    for i in 0..6
      @b[i] = Wx::Button.new(@mypanel, i, "#{i}", [10+25*i, 10],
[20,20])
      evt_button(i){puts i}
    end
  end

end

Wx::App.run do
  FFF.new.show
end
--------

1) I'm create pre-condition number of buttons(7 in example above). What
I must do to set every button event which puts button id(btw, it's equal
label of buttons too)? For example: if I print button "0", it must puts
0, not 6 as a my code(in my code click to all buttons puts last number
in array, here it is 6).

2) Are there events to images such as click and mouse_on?

Subject: [wxruby-users] Scrolling / wxPanel / wxFlexGridSizer
Message-ID: <677d267f9fc09687e9ea7f8a1a7793ec@ruby-forum.com>

I have a problem getting scroll bars to become active.  Scrollbars
appear but do not actually scroll.  The problem I am trying to
solve is to list a large number of key/value pairs.  I looked
to use PropertyGrid but did not find it in wxruby 2.0.1.  I'm
really stuck and would appreciate any help.

Thanks,
Dave

Details:

I am starting with an .xrc file containing:
    ...
    wxStaticBoxSizer (horizontal, stretch factor 1, expanded vertically)
        wxPanel (stretch factor 1, expanded vertically)
    ...

In the ruby file invoking the interface I have:

require 'wx'
require 'loadgui.rb' # from xrcise

class MyApp < MyGUI
  def on_init
    # Sizer holding key value pairs
    @settings_sizer = Wx::FlexGridSizer.new(2)
    @settings_sizer.add_growable_col(1, 1)

    # wxPanel holding the sizer above
    @panel       = @finder.call( 'ID_SETTINGS' )
    @panel.sizer = @settings_sizer

    @labels = {}
    @texts  = {}
    ENV.each { |k, v|
      @labels[k] = Wx::StaticText.new(@panel, :label => k)
      @texts[k]  = Wx::TextCtrl.new(@panel, :value => v)
      @settings_sizer.add @labels[k], 0
      @settings_sizer.add @texts[k], 1, Wx::EXPAND
    }
  end
end

# Run the Application
Wx::App.run do
  $app = MyApp.new
  $app.show
end

This is answered in-line in the code.

I believe the standard event handlers for StaticBitmap will work, as
it's hierarchy is Object > EvtHandler > Window > Control > StaticBitmap.

Standard Images, through Wx::Image, Wx::Bitmap, and such, do not have
Events, as they are considered Memory Objects, not Actual Controls.

Basically, if you look at the docs for any class we have, and it has
somewhere in it's hierarchy EvtHandler, then there are events that the Class
will receive.

Mario

We don't have PropertyGrid available in 2.0.1, but we do have Wx::Grid
available, which should allow you to use a Key > Val pairs setup in it, as
well as Wx::ListCtrl.  Take a look at these two classes' documentation, to
see if it will help you.

1) evt_button(@b[i]) { puts i } doesn't work I need. It works like a 
evt_button(i){puts i}. I don't know why.

Hi!

That's the way to do it - it's not very clean since it probably will be 
triggered by any button event
but you can process only events starting with a specific value etc and 
ignore the rest (and use more strict handlers):

    class FFF < Wx::Frame
      def initialize
        @b = Array.new
        super(nil, 2, "Bljllll", [5,5], [640,480])
        @mypanel = Wx::Panel.new(self)
        for i in 0..6
          @b[i] = Wx::Button.new(@mypanel, i, "#{i}", [10+25*i, 10],
    [20,20])
        end
       # here you specify global event handler which
      # will process any button press
      # this uses event delegation and works dynamically
      # so it will works regardless of number of buttons
        evt_button(Wx::ID_ANY){ |ev| puts ev.get_id }
      end

    end

If you want clickable images you should use Wx::BitmapButton class: 
http://wxruby.rubyforge.org/doc/bitmapbutton.html

Hope that helps :-)

I'm sure it's not good for your sanity, but I just found out that our
beloved problem isn't limited to Ubuntu. Yesterday I decided to give
Arch Linux a try and today I wanted to do some developing with wxRuby,
but nope. Here's what I did:

* Compiled Ruby 1.9.2-p0 to /opt/rubies/ruby-1.9.2-p0
* Compiled wxRuby on top of Arch's distro wxWidgets
* Installed the wxruby-ruby19 gem I just compiled

And now the expected segfault:

You may have encountered a bug in the Ruby interpreter or extension

For details: http://www.ruby-lang.org/bugreport.html
=========================================

The issue is definitely related to libpixman's version and not to
Ubuntu's modifications I conclude. But that means, if the other distros
update their libpixman, wxRuby won't work ony any of them... :-(

This is the pixman lib Arch uses:

Subject: [wxruby-users] Force wxRuby/wxWidgets to Qt libs?
Message-ID: <4CE16933.40105@gmx.net>

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi there,

Being annoyed by the libpixman bug wxRuby has I wonder wheather I could
just make wxRuby use the Qt libs instead of the GTK ones. I already have
them installed on my Ubuntu machine, as I'm using applications like K3b
which clearly come from KDE and therefore use the Qt library.

So here's my question: Is there an easy way to make wxRuby/wxWidgets use
the KDE/Qt libraries instead of the GNOME/GTK ones from a normal Ubuntu
session? Maybe just by setting an appropriate environment variable such as
$  WX_WIDGETS_LIB=Qt ruby my_gui.rb
?

Valete,
Marvin

Hi

Yes, there is evt_right_down, evt_right_up and evt_right_dclick (and 
also similar events for the middle button).

Note that if you're creating context menus (a common use for right 
clicks) it is better to use evt_context_menu which abstracts away 
platform differences in the means by which such a menu is summoned and 
dismissed.

No, I'm afraid not. The QT port of wxWidgets is largely unmaintained. 
Also, the port of wxRuby to each platform/lib requires special work, and 
there isn't any support in the wxRuby codebase for building against QT.

Why not just use QT/Ruby? It is different but has a similar range of 
features to wxRuby.

I already thought about that, but I have so much code that is already
written for wxRuby... I don't want to rewrite all that. Additionally, Qt
doesn't look native on other platforms than those using KDE, which is a
must-have for many of my applications (at least Ubuntu and Windows).

Thanks for the help Mario.

I did look at grid and listctrl. I had hoped to use a FlexGridSizer
instead, because I wanted columns of different sizes and to have
one column grow.  ListCtrl looks fairly complicated.

My problem seems to be getting the parenting or settings correct
to have scrollbars work when I fill the FlexGridSizer beyond its
window capacity.  The scrollbars appear, using a settings of the
wxPanel, but mouse clicks on them don't cause scrolling.

My hierarchy looks like:
    ...
    wxStaticBoxSizer (horizontal, stretch factor 1, expanded vertically)
        wxPanel (stretch factor 1, expanded vertically)
            wxFlexGridSizer (2 cols, col 1 growable, stretch factor 1)
                wxStaticText
                wxTextCtrl
                ...
                wxStaticText
                wxTextCtrl
    ...


Thanks,
Dave

evt_button(10){puts "This is button-10"} # Here is event for left-click 
mouse.

Can you write event for b, but with the right click?

It is easy to do:
evt_button(@button) do
  self.close
end

If that is the only window you have, the app should end on it's own, otherwise you will need to call Wx::App.exit_main_loop

Hi!

The docs for TaskBarIcon provide you with an explanation: 
http://wxruby.rubyforge.org/doc/taskbaricon.html#TaskBarIcon_createpopupmenu

If you aren't planning to add any menus for the dock icon you can simply 
use this method: https://gist.github.com/709130


Hope that helps!

Message-ID: <AANLkTi=EDw_o0KXfzzhmv5eEJ6Kiu6azhfy7J-j5nhbk@mail.gmail.com>

Hello, all -

I'm having a grand time making cpu stats for an embedded board show up in my
ruby app, but I have run into a roadblock. I used RMagick's RVG graphics to
create the graph, and it works fine when I just dump it to an image file
such as .png. I'm trying to eliminate that step and write it directly to a
panel in my Wx gui, but it appears -- and there's a statement in the docs
that confirms it -- that RVG::Image != Magick::Image. I experimented quite a
bit with the sample program that takes a RMagick image and inserts it, but I
haven't been able to make those techniques work for RVG. Is there a
conversion?

I've started looking at the Wx GraphicsContext methodology, but it isn't as
elegant. Suggestions?

wxRuby 2.0.1
RMagick 2.12.1
Ubuntu 9.10 32 bit
Ruby 1.87 p 302

Maybe Wx::ScrolledWindow? Have a look at the samples as there are 
several ways to use this class. The easiest way is with sizers where the 
scrolling will be calculated automatically for you.

Is it strictly GUI code that takes ages to run?

What you could do if there is a lot of computation involved in updating 
the GUI is have the process which works out what needs to be changed 
running in a separate thread, then posting messages to the main thread 
so that the actual visual update takes place incrementally whilst the 
GUI remains responsive.

Another option is just to run the updating code in an evt_idle loop - 
again, it will only happen when there is spare time to update the GUI.

I don't think it will do anything that Ruby (1.9) native OS threads 
can't do?

I'm not completely sure I understand what you want to do - but I think 
the easiest way is to Wx tell RVG to render the vector at a given 
resolution in a well-known bitmap format (eg PNG), and then display that 
in Wx.

You can bypass writing the rendered image to disk by using Image.read, 
and a StringIO if necessary - so it can just be passed about in memory. 
Re-render the image when the display size changes. You might find 
something useful in my Ruby Quiz response for a Wx Mathematical Image 
Generator:

Alex, thanks!

Your presentation and the sample file in wxruby samples were outstanding and
a heck of a lot of fun to play with. Some of the other demos get too cute
for their own good, but yours was very clear. I am using it to figure out
how to get my DC from point-painting to lines.

I have decided to rework my code so that the graph-drawing code is embedded
in the Window subclass and done completely in wx DC methodology. It's not as
straightforwardly obvious and Ruby idiomatic, but I'm making it work and the
code outside of the graph-drawing routine is getting much cleaner.

Subject: [wxruby-users] direct painting on bitmap
Message-ID: <AANLkTi=6Kcxnp5o1yyAkVR=uEOnMCe6iyrmuXgqiULix@mail.gmail.com>

Hi, All -

I've been getting closer and closer to a raw painting interface (see 'Inserting
RMagick RVG images in wxRuby' for my starting point) and now what I'm
working on (yes, I'm getting paid to work today; my kids are 3000 miles away
so it's a welcome distraction) is drawing on a MemoryDC associated with a
bitmap:

        @picture = Bitmap.new( size_x, size_y )
        artist = MemoryDC.new
        artist.select_object @picture
        artist.set_background_mode SOLID
        artist.flood_fill( 160, 200, Colour.new( 240, 0, 0, 255 ) )

... and later:

        paint_bitmap( @picture, client_size.x, client_size.y )

using the definition (part of my Window sub-class):

    def paint_bitmap bitmap, width, height
        bitmap = make_dummy if bitmap == nil # dummies for non-existant
images (like cpu1 if single-thread)
        rescaled_bitmap = Bitmap.from_image(
bitmap.convert_to_image.rescale( width, height ), -1 )
        rescaled_bitmap.save_file( @fname, BITMAP_TYPE_XPM )
        paint do | renderer |
            renderer.draw_bitmap( rescaled_bitmap, 0, 0, false )
        end
        @sized = false
    end

What appears to be happening is that my bitmaps are not taking over from the
original contents of the memory arrays, because what I see being rendered
appears to be garbage pages from the screen buffer. If I change something in
my GUI (like pressing a button, which changes its color to yellow), I see
smears of yellow showing up in my bitmaps and getting rendered in my GUI.

The Bitmap#draw method referenced in the DC and MemoryDC docs appears to
have gone bye-bye in 2.0, so I'm using the direct instantiation menthod. I
finally got my copy of Smart and Hock and it says something about
select_object not working if the bitmap is unpopulated, so my next try is to
pull up a base bitmap from a file instead of creating one from new.

Thanks in advance! :D

Bitmap#load_file is also gone, but Bitmap.new has a file option. Never rely
on a first-release API to be as documented. ;-)

Changing make_dummy to load a file got rid of the uninitialized bitmaps, but
I still can't paint anything on them. The above code should leave me with a
screaming red bitmap, but all I get is the white from my blank.png.

Calling all wxRuby developers, experts, and hackers!

My company is looking to contract with one or more individuals to
complete a pair of programming tasks as a work-for-hire.  The tasks
are improvements for an open-source project called wxSU--a glue layer
that couples wxRuby to the Ruby API in Google SketchUp.

Depending on the task, applicants should have expertise
"under-the-hood" of wxRuby, wxWidgets, or Ruby, or experience with
low-level GUI programming.

See the full description of the tasks here:
http://bigladdersoftware.com/wxruby.pdf

Thanks!

I wouldn't call a project with a stable, complete release across half a 
dozen platforms 'dead' - but it's true that little or no new code has 
been committed in the past 12 months or so since the release of 2.0.1. I 
led the development of 2.0 but have been doing other non-programming 
things, but am around on the mailing list along with other devs. 
Hibernation maybe?

cheers

as a sacrificial offering) could get the docs updated to match the new code
base. It is very frustrating to discover that half the 'overviews' are gone
completely, and wxRuby is vastly different from wxC++ in the way things like
Device Contexts and such are instantiated. I have been able to get my code
to work well (after reading and re-RTFM-ing), but I'll bet it would be even
better if I knew the little bits of tribal knowledge that you have stored in
your collective brains.
