Subject: Elementary FXDialogBox query

Hi

I'm trying to use a dialog box in FXRuby.
I have a class set up as follows

class AddItemDialog < FXDialogBox
  def initialize(owner)
    super(owner, "Add entry dialog")
    FXLabel.new(self, "Entry Name")
    textField = FXTextField.new(self, 20)
    buttons = FXHorizontalFrame.new(self, 
LAYOUT_SIDE_BOTTOM|FRAME_NONE|LAYOUT_FILL_X|PACK_UNIFORM_WIDTH)
    FXButton.new(buttons, "&Accept", nil, self, ID_ACCEPT, 
FRAME_RAISED|FRAME_THICK|LAYOUT_CENTER_X|LAYOUT_CENTER_Y)
    FXButton.new(buttons, "&Cancel", nil, self, ID_CANCEL, 
FRAME_RAISED|FRAME_THICK|LAYOUT_CENTER_X|LAYOUT_CENTER_Y)
  end
  def create
    super
    show
  end
end

When invoked I get the dialog that closes when either of the buttons is 
pressed and returne a 1 or a 0 depending on which button is pressed.
What I want to do is capture the text in the text field so i tried

class AddItemDialog < FXDialogBox
  def initialize(owner)
    super(owner, "Add entry dialog")
    FXLabel.new(self, "Entry Name")
    textField = FXTextField.new(self, 20)
    buttons = FXHorizontalFrame.new(self, 
LAYOUT_SIDE_BOTTOM|FRAME_NONE|LAYOUT_FILL_X|PACK_UNIFORM_WIDTH)
    FXButton.new(buttons, "&Accept", nil, self, ID_ACCEPT, 
FRAME_RAISED|FRAME_THICK|LAYOUT_CENTER_X|LAYOUT_CENTER_Y)
    FXButton.new(buttons, "&Cancel", nil, self, ID_CANCEL, 
FRAME_RAISED|FRAME_THICK|LAYOUT_CENTER_X|LAYOUT_CENTER_Y)
    if self.execute != 0
      puts textField.text
    end
  end
  def create
    super
    show
  end
end

Now if the accept button is pressed it returns the text field entry but the 
dialog box stays visable, if the accept button is pressed again the dialog 
disappears and it returns 1.

Any pointers would be gratefully received.

Cheers
Nigel
