Transform your Smartphone into Thermal camera

Thermal imaging camera is a device that forms an image using infrared radiation, similar to a common camera that forms an image using visible light. Now, a thermal imaging camera which can embedded on smartphone have been developed.

The Seek device enables you to turn your smartphone into thermal imaging camera supporting both Android and iOS.

Google I/O 2015 keynote Full

Have you missed to watch Google I/O 2015 keynote event on last Thursday?

If so, you can watch the complete events here. You will see the update-to-date technologies. What new features will google include in it products? 

You will be able to answer to this question by watching it.

Laying out Widgets, Creating Spinbox, Slider, Textbox

In the previous tutorial, you have learned how to create a label and a button in Qt. Qt is designed to simplify C++ programmer to create a nice GUI for their application. Therefore, it provides a wide variety of widget classes to create a cool GUI which is divided into groups such as Layouts, Buttons, Item views, Input Widgets, so on and so forth.

Window Flip 3D

By using Window Flip 3D feature, it enables you to swiftly preview all of your open windows (for example, open files, folders, and documents) without having to click the taskbar. Flip 3D feature activated an Alt-Tab-like window switcher when you pressed the Windows key and Tab at the same time. However, Flip 3D displays through larger window thumbnails to select an open window.

Disable Aero Shake in Window 7

In the previous tips, you have seen the handy feature in window 7 to quickly focus on a single window you’re working on with simple mouse shake which is called Aero Shake. 

How to disable this feature?

In this tutorial, we will guide you how to disable this feature in case you want. You can do that by using Group Policy Editor

Aero Shake in Window 7

In the past, we are allowed to work with one task at a time.  Nowadays, the power of personal computer has increased sharply so we almost always work simultaneously.

In order to easily keep your workspace free, window 7 includes several gesture features allowing you to easily minimize all running window except the one you’re working on with a simple mouse shake.

Introduction to OpenGL Core Profile

OpenGL is one of the most popular multi-platform application programming interface (API) used to produce three dimensional computer graphics applications.

Since version 3.0, it is known as the new era in the evolution of OpenGL because a wide range of new features were added as well as marking the old fixed functions as deprecated that will be completely removed from the core profile in version 3.1. Because of deprecation, GL ARB compatibility extension was added to OpenGL in an attempt to enable graphic programmers to access the old fixed functions.

In this work, we have decided to opt OpenGL core profile 3.3 based primarily on OpenGL shading language (GLSL) because it is efficient programming and programmable. Moreover, it easily switches to OpenGL ES or WebGL which are compatible with modern OpenGL core profile.

Basic Qt

Prerequisite

1. Qt Creator with MinGW or Visual C++


2. Knowledge of C++


3. Qt Library

If you have limited experience with C++, please take a look at C++ tutorial before proceeding this tutorial.

The only way to learn a new programming is by starting to write program and play around with it. In this tutorial, we start to write a basic Qt program by using basic functionality of C++ provided by Qt to create a small graphical user interface (GUI). As we have already experienced when we start to learn the programming language, we usually begin with "Hello World". Therefore, we also start with the "hello Qt".

Create HelloQt.cpp

1 #include <QApplication>

2 #include <QLabel>

3 #include <QPushButton>

4 int main(int argc, char *argv[])

5 {

6    QApplication app(argc, argv);

7    QLabel *helloLabel = new QLabel("<font color=blue><b><center>Hello  
      Qt!</center></b></font>");

8    QPushButton *helloButton = new QPushButton("Push me to say Hello");

9    QObject::connect(helloButton, SIGNAL(clicked()), helloLabel,  
      SLOT(show()));

10   helloButton->show();

11   return app.exec();

12   }

Why Qt?

Qt software framework has become a popular cross-platform application framework since its release in 1995. It is widely utilized for developing industrial application software with professional graphical user interfaces (GUIs). With Qt, C++ programmers are easy to build user interface for their applications by dragging and dropping using its GUIs designer. Beside GUIs, Qt is also allowed us to instantiate the class or subclass in order to construct GUIs. Throughout this tutorial, we are going to talk about how to do subclass and instantiate of Qt widgets later. Qt provides main window are generally divided into five sections. In the first section is occupied by the menus followed by toolbars in the second section. 

Qt Creator

Qt creator is the cross platform C++ Integrated Development Environment (IDE) which provides a set of helpful features for assisting developer during the software development process. Those features are listed as the following:

•     Static code checking and style hinting when typing
•     Syntax highlighting and code completion
•    Context sensitive help
•   Highlighting and folding blocks
•   Parenthesis matching, and parenthesis selection modes
