Hi, I get the following message when trying to use Tk  
"This application has failed to start because tk84.dll was not found.  
Re-installing the application may fix this problem."

I am using Ruby 1.8.4.

Has anyone else come across this? I thought Tk was included in ruby.

Or am I missing something?

Chris.

Youre missing par example activetcl from activestate if you are using windows.

Sorry for double posting.  
In Ruby are only the bindings to tcl. You need a tcl distribution wich you can get her for example:

Choose here ActiveTCL (its free)

I have got Tk working - but now want to use Tile to give native look and  
feel.  
I have used the following code:  
Tk::Tile.\_\_Import\_Tile\_Widgets\_\_

but get in reply:

uninitialized constant Tk::Tile  
from C:/InstantRails/ruby/lib/ruby/1.8/tk.rb:1869:in `const\_missing'

Tile appears in:  
C:\InstantRails\ruby\lib\ruby\1.8\tkextlib

How do I make it work?

Chris

Did you call "require 'tkextlib/tile'"?  
If so, did you install Tile extension for your Tcl/Tk?

# ActiveTcl binary package includes Tile extension.

That is a wrapper library for Tile extension.  
It requires Tcl/Tk's Tile libraries.
