示例1: showEntry

		void Preferences::showEntry(QWidget* child)
		{
			if (!widget_to_item_.has(child)) 
			{
				widget_stack->setCurrentIndex(0);
				return;
			}

			// enable or disable help button
			HelpViewer* hv = HelpViewer::getInstance(0);
			if (hv != 0) buttonBox->button(QDialogButtonBox::Help)->setEnabled(hv->hasHelpFor(child));

			// set the listview entry 
			QTreeWidgetItem* item = widget_to_item_[child];
			entries_listview->setCurrentItem(item);
			entries_listview->setItemSelected(item, true);
		
			if (item->parent() != 0) entries_listview->setItemExpanded(item->parent(), true);

			// is the child a direct child of the stacked widget?
			if (widget_stack->indexOf(child) != -1)
			{
				// show the child 
				widget_stack->setCurrentWidget(child);
				widget_stack->currentWidget()->show();

				return;
