Generally speaking, SEL_CHANGED messages are usually sent while a 
widget's value is changing, and SEL_COMMAND when it is "finished". So, 
for example, an FXSlider widget will send SEL_CHANGED messages 
continously to its target while you're dragging the slider back and 
forth, but will only send SEL_COMMAND to its target when you stop 
dragging and release the mouse button. In the same way, an FXTextField 
sends SEL_CHANGED to its target every time the text field's contents 
changes (e.g. by adding or removing a character), but it only sends 
SEL_COMMAND when you press <Enter> or tab out of the text field.

So try modifying the previous snippet from this:

     @datatarget.connect(SEL_COMMAND) do |s,i,data|
	puts "#{data},#{@name}"
     end

to this:

     @datatarget.connect(SEL_CHANGED) do |s,i,data|
	puts "#{data},#{@name}"
     end

and see if you get the result you expected.

Hope this helps,
