@JKSH said in Qt for Beginners is not for Qt 5.5!:

http://doc.qt.io/qt-5/gettingstartedqt.html

FYI
This link: https://doc.qt.io/qt-5/gettingstartedqt.html
now results in a 404 error.
Note: only a slight change: drop the "qt" just before the .html
Try a new link: https://doc.qt.io/qt-5/gettingstarted.html

Now i have better understood the dynamics of connect.

Thanks for your patience.

Then it's just a matter of removing from the list items that are already added. Something like this:

//get the list from somewhere QStringList fileNames = ... //remove the temp item you mentioned fileNames.removeOne(temp); //remove the items already in the widget int numItems = listWidget->count(); for(int i = 0; i < numItems; ++i) fileNames.removeOne(listWidget->item(i)->text()); //now that the list is "clean" all there is left to do is add the new items listWidget->addItems(fileNames);

Welcome to the world of Qt :) Happy coding!

Thank you very much!

@mcosta Hi,

I'll certainly take a look at it. So I guess it's not only changing the font xD

Thank you.

Since you talked about QML I will assume that you work with embedded devices so SQLite is probably the database for you.
Here is an example of how to connect to a database, hope this helps:

QSqlDatabase db = QSqlDatabase::addDatabase("SQLITE"); db.setDatabaseName("path/to/database.db"); db.open(); //This will create the database if it doesent exist

Make sure to include

#include <QSqlDatabase>

Also add

QT += sql

To your project file

Thanks a lot for your pointers (no pun intended :-)

If you want to do it widget style you might be interested by this

Otherwise, are you going to use QML ?
