PyGTK: issue packing widgets into dialog

[maddog39]

Hello all,

I've been having a ton of trouble with this custom gtk dialog I am trying to create. The code "runs" however I receive a GtkWarning message saying:

/home/maddog39/Projects/mmoalert/actiondialog.py:42: GtkWarning: gtk_box_pack_end: assertion `child->parent == NULL' failed
  self.message_hbox.pack_end(self.message_entry)

For the life of me, I can't seem to figure out what going on and why this is happening. As usual, its probably something very simple that keeps passing by me. Heres the code for the dialog.

import gtk, utils

ACTIONDIALOG_TYPE_ADD  = 0
ACTIONDIALOG_TYPE_EDIT = 1

class ActionDialog(gtk.Dialog):
	def __init__(self, type, app, title=None, content=None):
		gtk.Dialog.__init__(self, None, None, gtk.DIALOG_MODAL)
		
		if type == ACTIONDIALOG_TYPE_ADD:
			self.set_title("Add New Article")
		else:
			self.set_title("Edit Article")
		
		# Setup dialog widgets
		self.title_label = gtk.Label("Title")
		self.title_entry = gtk.Entry(max=180)
		self.message_label= gtk.Label("Message")
		self.message_entry = utils.TextField()
		self.message_entry.set_wrap_mode(gtk.WRAP_WORD)
		
		# Fill fields with data if in edit mode
		if title != None and content != None:
			self.title_entry.set_text(title)
			self.message_entry.set_text(content)
		
		# Create boxes to hold widgets
		self.title_hbox = gtk.HBox()
		self.title_hbox.pack_start(self.title_label)
		self.title_hbox.pack_end(self.title_entry)
		self.message_hbox = gtk.HBox()
		self.message_hbox.pack_start(self.message_label)
		self.message_hbox.pack_end(self.message_entry)
		# DEBUG: not working properly
		# Pack Widgets into vertical box
		self.vbox.pack_start(self.title_hbox)
		self.vbox.pack_start(self.message_hbox)
		
		# Add the buttons to the dialog
		self.add_button(gtk.STOCK_SAVE, gtk.RESPONSE_ACCEPT)
		self.add_button(gtk.STOCK_CANCEL, gtk.RESPONSE_REJECT)

Help much appreciated.

Thanks!
