fxruby users - Aug 2007 - setting the font in FXText

I have subclassed a FXDialogBox and put a FXText in it for displaying a
hex dump in my application. I want to change the font to a courier type
font since it''s a hex dump. When do the following it works as expected:
 
# A little dialog box to use in our tests
class FXTextDialog < FXDialogBox
  def initialize(owner)
    # Invoke base class initialize function first
    super(owner, "Temp", DECOR_TITLE|DECOR_BORDER, 0, 0, 200, 200)
 
    button = FXHorizontalFrame.new(self,
      LAYOUT_SIDE_BOTTOM|FRAME_NONE|LAYOUT_FILL_X|PACK_UNIFORM_WIDTH)
    contents = FXHorizontalFrame.new(self,
 
LAYOUT_SIDE_TOP|FRAME_NONE|LAYOUT_FILL_X|LAYOUT_FILL_Y|PACK_UNIFORM_WIDT
H)
  
    @fxtext = FXText.new(contents, nil, 0,
TEXT_READONLY|TEXT_WORDWRAP|LAYOUT_FILL_X|LAYOUT_FILL_Y)
    @fxtext.font = FXFont.new(getApp(), "courier", 8)
 
    # Ok button
    ok = FXButton.new(button, "OK", nil, self, ID_CANCEL,
 
FRAME_RAISED|FRAME_THICK|LAYOUT_CENTER_X|LAYOUT_CENTER_Y|LAYOUT_FILL_X)
    ok.setDefault  
    ok.setFocus
  end
end

However, when I add the following method to FXTextDialog and call it I
get a Seg Fault!:
  def set_font()
    @fxtext.font = FXFont.new(getApp(), "courier", 8)
  end
 
Usage in my application:
  def onTableHex(sender, sel, ptr)
    @dialog = FXTextDialog.new(self)
    @dialog.set_font()
    @dialog.show
  end
 
How do I set my font once I have already created the dialog box or is
this possible?

You need to call create() on the font before you assign it:

     def set_font()
       font = FXFont.new(getApp(), "courier", 8)
       font.create
       @fxtext.font = font
     end

There''s also an entry about this in the FOX FAQ (see http://www.fox- 
toolkit.org/).

Hope this helps,

I think you need to call create on the font before using it like so:

  def set_font()
    myfont = FXFont.new(getApp(), "courier", 8)
    myfont.create
    @fxtext.font = myfont
  end
