Hands-On GUI Programming with C++ and Qt5

Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "We call the test() function at the MainWindow constructor."

A block of code is set as follows:

void MainWindow::test() 
{ 
   int amount = 100; 
   amount -= 10; 
   qDebug() << "You have obtained" << amount << "apples!"; 
} 

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

MainWindow::MainWindow(QWidget *parent) : 
   QMainWindow(parent), 
   ui(new Ui::MainWindow) 
{ 
   ui->setupUi(this); 
   test(); 
}
