Qt 4 for Beginners
Qt 4 for Beginners
English Edition
About the Book
Throughout this book is an Image Down Sizer program that is more completed than a Hello World example. It is, of course, an image processing application. You will learn how to make such a program from scratch. As a mentor for beginners, I will divide the implementation into many paragraphs and steps with a lot of description and explanations.
Qt 4 Not Die
It is already the Qt 5 era. Why such a Qt 4 book is still worth for reading? I think there are two reasons:
- Must maintain old Qt 4 projects
- Not yet upgrade to Qt 5 Enterprise License
As a result, Qt 4 does not die, it just fade away.
At Meet Qt in Taipei Seminar, held on 12 March 2014, the speaker Xia Chunmeng from Digia Beijing asked the audience and found out that:
- Only one-third of the 70 people start using QML
- Half of the 70 people are still working on Qt 4
I am certainly working hard to revise my book to migrate it to the successor edition Qt 5 for Beginners. I will offer my readers a coupon code to buy the new book at a discount so it is still time to buy the book now.
