Hi,

Thanks @SGaist ;
And "this" refers to what in this line of code :
connect(m_ui->sendFrameBox, &SendFrameBox::sendFrame, this, &MainWindow::sendFrame);

Hi
the this in the connect is the Mainwindow which has the sendFrame method.

So it says
connect sendFrameBox's signal sendFrame to MainWindows's slot called sendFrame
