Initialise()

mMainWindow = CEGUI::WindowManager::getSingleton().loadWindowLayout("chat.layout");
if (mMainWindow)
    getMainSheet()->addChildWindow(mMainWindow);
CEGUI::Window* pEditBoxWnd = CEGUI::WindowManager::getSingleton().getWindow((CEGUI::utf8*)
"/Chat/Wnd/Edit");
BIND_CEGUI_EVENT(pEditBoxWnd, CEGUI::Editbox::EventTextAccepted,
    ChatWidget::EditTextAccepted)
mEditBox = static_cast<CEGUI::Editbox*> (CEGUI::WindowManager::getSingleton()
    .getWindow("/Chat/Wnd/Edit"));
mListBox = static_cast<CEGUI::Listbox*> (CEGUI::WindowManager::getSingleton()
    .getWindow("/Chat/Wnd/List"));

getMainSheet() in this case returns the main default gui sheet (root) window

EditTextAccepted()

bool ChatWidget::EditTextAccepted(const CEGUI::EventArgs& args)
{
	//add text to list
	CEGUI::ListboxTextItem* item = new CEGUI::ListboxTextItem(mEditBox->getText());
	mListBox->addItem ( item );
	mListBox->ensureItemIsVisible(mListBox->getItemCount());
	//remove old text
	mEditBox->setText("");

	return true;
