Qt - What do we mean by those code snippets

[C++ Programming]

End Google Ads 201810 - BS.net 01 --> I just have those questions about those code sinppets from the C++ GUI Programming with Qt 4 book:

GoToCellDialog::GoToCellDialog(QWidget *parent):QDialog(parent)

Does that mean we are inheriting QDialog(parent)? Or, what exactly does this mean?

setupUi(this);

Here, this code snippet is part of the gotocelldialog.cpp file, which is the implementation of gotocelldialog.h header file. What do we mean by this in this context? What are we trying to setup? And, what kind of setup will that be?

Thanks.
