Need a simple graphics interface/function for ruby

Hi,

I'd like to have an M x N array of characters which I can address (say, by Row and column) and update or read any spot (M,N). This array would map directly to a window. can anyone suggest the best/easiest way to implement this? In other words, I'm looking for a way to display an array of characters to a Window....

Thanks,

Chuck

Ps. I have FXRuby installed, I probably just need to be shown a sarting point maybe an FX Ruby function????

Re: Need a simple graphics interface/function for ruby

Hi,

I have no idea how FXRuby works, but I guess every GUI framework has 
some kind of table object. For example, in Ruby-GNOME2 you'd use a 
Gtk::Table and put a Gtk::Label with the corresponding character in 
every cell.

However, you won't be able to base this table on a normal array and have 
every update to the array directly update the GUI object. You'll need a 
custom object for that, which also updates the GUI object on change.

Re: Need a simple graphics interface/function for ruby

here a example with gtk by a littlr dsl
> ... install gtk2
> gem install Ruiby

and then :

require 'ruiby'
M=12
N=10
Ruiby.app width: 400, height:400 do
  <at> matrix=[]
 table(M,N) do
    M.times {
    line=[]
    row {
      N.times {
        line << label("   ")
        cell(line.last)
      }
    }
     <at> matrix << line
  }
 end
 anim(10) do
     <at> matrix[rand(M)][rand(N)].text = (Time.now.to_i%10).to_s
 end
end
