fxruby users - Feb 2008 - FXRuby, blocks and hash (? should this work}

Example code (:opts omitted)

It is done in initialize of Win < FXMainWinow:

@cg = {}

FXMatrix.new {|m|
  FXLabel.new(m, "Log-in name: ")
  @cg[:login] = {:name => FXTextField.new(m, 25)}
  @cg[:login][:name].setFocus

  p @cg[:login][:name].class

  FXLabel.new(m, "Password: ")
  @cg[:login] = {:password => FXTextField.new(m, 25)}
}

p @cg[:login][:name].class

output is:

Fox::FXTextField
NilClass

The question is, why id disappears?

Should be "... why _it_ dissapears?" (i.e. becomes NilClass)

You overwrote the @cg[:login] hash with a new hash that only contains
:password.  

The following change should fix it.

Was:
@cg[:login] = {:password => FXTextField.new(m, 25)}

Is:
@cg[:login][:password] = FXTextField.new(m, 25)

Hope this helps,
Ryan
