The following is a simplified example from the wxRuby wiki here:

[http://wxruby.rubyforge.org/wiki/wiki.pl?Frames\_(Part\_1)](http://wxruby.rubyforge.org/wiki/wiki.pl?Frames_(Part_1))

It’s the second example in the wxRuby tutorial entitled “Getting  
Started”. However, I don’t seen any icon when I run the code on mac osx  
10.4.11.

require ‘rubygems’  
require ‘wx’

class IconFrame \< Wx::Frame

def initialize  
super(nil, -1, “Changing Icons”, Wx::DEFAULT\_POSITION,  
Wx::Size.new(300, 200)  
)

```
set_icon(Wx::Icon.new("./icons/DataHD.png"))

show

```

end

end

class MinimalApp \< Wx::App  
def on\_init  
IconFrame.new  
end  
end

MinimalApp.new.main\_loop

I also tried using some .ico files in set\_icon(), but I don’t see them  
anywhere.

Frames in the OS X desktop don’t have icons - not in the same way as  
Windows has per-frame icons in the top-left corner.

If you want to set an application-wide icon to appear in the Dock, use  
Wx::TaskBarIcon. There’s an example of this in the bigdemo.rb sample  
that comes with wxRuby.

PS - wxRuby questions are better on the wxruby-users mailing list:

Thanks for the response. Ok. Maybe the wiki should mention that?

By the way, did you see my results here:
