Overview of this book

Qt 5.7 is an application development framework that provides a great user experience and develops full-capability applications with Qt Widgets, QML, and even Qt 3D. This book will address challenges in successfully developing cross-platform applications with the Qt framework. Cross-platform development needs a well-organized project. Using this book, you will have a better understanding of the Qt framework and the tools to resolve serious issues such as linking, debugging, and multithreading. Your journey will start with the new Qt 5 features. Then you will explore different platforms and learn to tame them. Every chapter along the way is a logical step that you must take to master Qt. The journey will end in an application that has been tested and is ready to be shipped.

Preface

Examining the memory with Qt Creator


For this section, we will use the following code snippet:

bool boolean = true; 
int integer = 5; 
char character = 'A'; 
int* integerPointer = &integer; 
 
qDebug() << "boolean is:" << boolean; 
qDebug() << "integer is:" << integer; 
qDebug() << "character is:" << character; 
qDebug() << "integerPointer is:" << integerPointer; 
qDebug() << "*integerPointer is:" << *integerPointer; 
qDebug() << "done!"; 

We declared three primitive types: booleaninteger, and character. We also added a  integerPointer pointer that refers to the integer variable. Put a breakpoint at the last line and start the debugging. On the Debug pane, you should have the Locals and Expressions view. You can easily add/remove it from WindowViewsLocals and Expressions. Here is a screenshot of it:

You can see that all our local variables are displayed with...
