OnClosed & OnFailed Doesn't receive (QT)

[xMuratY]

Onclosed and onfailed events never working.

` _io->set_close_listener(std::bind(&MainWindow::OnClosed, this, _1)); _io->set_fail_listener(std::bind(&MainWindow::OnFailed, this));

void MainWindow::OnClosed(client::close_reason const & reason) { Q_EMIT DisableUI(false); } void MainWindow::OnFailed() { Q_EMIT DisableUI(false); }`
