if you encounter a problem saying "File not found: mainwindow.obj" after adding the second window, the try the solution as follows Right click on project > Clean Right click on project > Run qmake Right click on project > Build Run - worked first time Actually, in the previous lecture I have already met with this problem when adding the second window, the solution of which seems to be tricky, but anyway hope it works well for you.

[@martindvorecky6189]

You must build *.ui after add any widget and before write method. Always.

Does hide() mean that the window process is running in the background?

[@valizeth4073]

If u want to open a second window just add QWidget* window = nullptr; // In the mainwindow.h tab and write window = new QWidget; window->setWindowTitle("your window's title"); window->resize(your size in int); window->show(); //in the login function and write delete window; // in the class's destructor

[@user-ww2lc1yo9c]

Why do we keep using the -> operator so much instead of using . operator? The . operator is used for things that mean member of, but we are just using the -> operator everywhere!

[@xanthos733]

Worked fine thanks for the tutorial

THANKS FOR SHARING !!!!

[@jonequest4262]

Hey, nice tutorials! Very easy to follow. I'm using QT on Ubuntu. I noticed, for example, that for the Group Box it does not show the borders like it shows on Windows. Do you know if this behavior is due to the operating system?

[@zhonghanliu6433]

May I ask why it is SecDialog *secDialog not Ui::SecDialog *secDialog?

[@tomaszbieniek3774]

You should deallocate memory which you allocate by using a "new" operator otherwise it leads to memory leak.

[@shashankmg]

I am getting 2 error as follows In file included from ../Login/main.cpp:1:0: Declaration of 'SecDialog* MainWindow::SecDialog'[-fpermissive] And one more of similar error.

how to make the username length ? is it username.size() like c++ ? pleaaase i want a response

[@zakariachahboun]

thank you very much ♥ ..... plz get a POP filter to your mic XD

[@davidlewisjr.8932]

How could we pass a variable, say a Qstring, to that new window? For example: login the first window, then on the second window display "{username} is logged in" ?

[@oblivionronin]

If that second window is a class. Option 1 : make it a constructor argument (coudl be optional argument) that you pass it to when constructing. Option 2 : simply call a setText() function on that second window before calling show(). Option 3 : create a username member variable in that class and set it before doing show()

[@amitjaiswalelect]

Excellent tutorial series.. I am getting an error "expected type-specifier before 'SecDialog'" for line "SecDialog = new SecDialog(this);".. What is going wrong?

[@valizeth4073]

Dont add a window that way, do it like this instead: QWidget* window = nullptr; // In the mainwindow.h tab and write window = new QWidget; window->setWindowTitle("your window's title"); window->resize(your size in int); window->show(); //in the login function and write delete window; // in the class's destructor
