A QT Quick based GUI application for displaying CPU Information from /proc/cpuinfo

Cute CPUInfo

Intro

Cute CPUInfo is an application that reads CPU Information from /proc/cpuinfo and visualize it using modern GUI based on QT Quick Controls

Technologies Used

C++11, QML, QT Creator, QT Quick, QT 5.9.1, Design Patterns, Regular Expressions, Git

Requirements

• Linux OS
• QT 5.9.1
• GCC

Build and run steps

$ make
$ ./MMostafaCPUInfo

UI Usage Guide

There are three main sections in the UI

Header

Has a top right button the display About application menu

Swipeview

• supports swiping left or right to naviagete between pages each displaying info about a single CPU Core
• supports scrolling up and down to disply detailed info about a CPU core

Footer

Indiacates the currently shown CPU core info and total number of cores

Software Design

The Software is implemented according to the QT Model-View Design pattern for supporting decoupling of CPUInfo data encapsulation (C++ Model) from the GUI controls that display the CPUInfo data (View)

The View is implemented in QML as cpuInfoListView located in main.qml The C++ Model is implemented as a derived class from QObject: CPUInfoElement

CPUInfoParser is the main Class in the application which parses the /proc/cpuinfo data using regular expressions and store them in the C++ Model. This class is implemented according to the Singlton Design patten for managing a single instance of the parser as well as a single instance of CPUInfoList.

CPUInfoParser::getCPUInfo() is static function that returns a CPUInfoList which encapsulate the C++ model, the model is passed as a context property in the main() function to expose the model to the QML view.
