	// We call this->close() instead of just 'delete this' in the accept callback.
	// This is because of how GuiComponent::update works. If it was just 'delete this',
	// the following would happen when the metadata resolver is done:
	//     GuiGameScraper::update()
	//       GuiComponent::update()
	//         it = mChildren.cbegin();
	//         mBox::update()

	//         mSearchComponent::update()
	//           acceptCallback -> delete this
	//         it++; // Error, mChildren has been deleted because it was part of 'this'.

	// So instead we do this:
	//     GuiGameScraper::update()
	//       GuiComponent::update()
	//         it = mChildren.cbegin();
	//         mBox::update()
	//         it++;
	//         mSearchComponent::update()
	//           acceptCallback -> close() -> mClose = true
	//         it++; // OK.
