Developing GUI programs using the Qt toolkit on Ubutnu based distros

<div dir="ltr" style="text-align: left;" trbidi="on">Earlier days, in Linux  machines developers used a single terminal ( command prompt ) to finish the tasks by simply entering the commands. But remembering all the commands leads complexity on linux for new people. So, developers decide to implement Graphical User Interface (GUI) to complete the tasks on Linux machines with echo friendly. Also developers globally build some FOSS tools to develop GUI programs for new developers. All the new developers are loved those FOSS tools and using that tools, they developed GUI programs. <br /><br />GUI programming is nothing but a X windowing system on Linux machine. This X windowing system provides windows on computer displays and interacts to users by accepting inputs from keyboards, control functions and touch screens etc.<br /><br />X windowing system uses GUI toolkits to help the development of GUI programs. <a href="http://en.wikipedia.org/wiki/Widget_toolkit%E2%80%8E" target="_blank">GUI Tookit</a> is a set of widgets for use in designing applications with GUIs. This toolkit based on different programming languages. C/C++ are the most commonly used in it. There are 2 popular GUI toolkits are used to develop GUI programs. Those are <a href="http://en.wikipedia.org/wiki/Qt_%28software%29" target="_blank">Qt</a> and <a href="http://en.wikipedia.org/wiki/Gtk%2B" target="_blank">GTk+</a>. Qt is developed in C++ while GTk+ is developed in C Language.<br /><br />Let we see about Simple 3 GUI programs to develop using Qt.<br /><br />Before starting the GUI programming with Qt , you must be install Qt Toolkit. <br />This package contains Qt 4 qmake (qmake-qt4), a tool that helps simplify the build process for development project across different platforms. qmake automates the generation of Makefiles so that only a few lines of information are needed to create each Makefile. qmake can be used for any software project, whether it is written using Qt or not.<br /><br /><span style="color: #0b5394;"><span style="background-color: white;"><br /></span></span><br /><span style="color: #0b5394;"><span style="background-color: white;"><i><span style="font-size: large;"><b>Installing Required Tools :</b></span></i></span></span><br /><br /><span style="color: #274e13;"><b>Step 1 : </b></span>Open Terminal by Accessories -> Terminal or press CTRL+ALT+T<br /><br /><span style="color: #274e13;"><b>Step 2 : </b></span>To install the required tools, copy the command and paste in to the terminal and press enter to install it.<br /><br /><blockquote class="tr_bq"><blockquote class="tr_bq"><i><span style="background-color: #cccccc;"><span style="color: #4c1130;"><b>sudo apt-get install qt4-qmake qt4-default qconf</b></span></span></i></blockquote></blockquote><br /><br /><span style="color: #274e13;"><i><b>qt4-qmake</b></i></span><br /><blockquote class="tr_bq">Qt 4 qmake requires a platform and compiler description file which contains many default values used to generate appropriate Makefiles. <span style="color: #274e13;"><i><b><br /></b></i></span></blockquote><span style="color: #274e13;"><i><b>qt4-default</b></i></span><br /><blockquote class="tr_bq">This package sets Qt 4 to be the default Qt version to be used when using development binaries like qmake. It provides a default configuration for qtchooser, but does not prevent alternative Qt installations from being used. </blockquote><span style="color: #274e13;"><i><b>qconf</b></i></span><br /><blockquote class="tr_bq">It is intended for developers who don’t need (or want) to use the more complex GNU autotools. With qconf/qmake, it is easy to maintain a cross-platform project that uses a familiar configuration interface on unix. </blockquote><br /><br /><span style="color: #0b5394;"><b><i><span style="font-size: large;">Developing GUI Programs : </span></i></b></span><br /><br /><span style="color: #274e13;"><b>Step 1 : </b></span>First create the common directory for Qt programs.

File Sharing using Samba on Ubuntu / Fedora / Linux Mint / Zorin OS / OS4 OpenLinux / Lubuntu / elementary OS / Bodhi Linux / Kubuntu / Ubuntu GNOME / Xubuntu / Pear Linux / Pinguy OS / Edubuntu

<div dir="ltr" style="text-align: left;" trbidi="on">In this post we will see about sharing files between two computers using a tool called samba.

Filesystem in Userspace ( FUSE ) Tutorial

<div dir="ltr" style="text-align: left;" trbidi="on">FUSE is an mechanism which allows to create own file systems to non-privileged users without editing the kernel code. Initially it was developed to support for AVFS ( A Virtual File System ). After that it will be taken as separate project. It runs file system code in user space while the FUSE module provides only a "bridge" to the actual kernel interfaces. Check the FUSE structure, it will help you to understand about FUSE.<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjfcm8uY8yNmonvTtLZnuqnAq-sG04vI3j5wZzWHeTcJmfq7O2iEKRpWdQQbYVSGeB6k1aKJTP8yLleHTlqSGr_FPvFsupsbuEhSEVQw9NSt4bVjV2AenXuzMsMW6o3fmC6FK8rEeo7pJY/s1600/fuse_structure.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjfcm8uY8yNmonvTtLZnuqnAq-sG04vI3j5wZzWHeTcJmfq7O2iEKRpWdQQbYVSGeB6k1aKJTP8yLleHTlqSGr_FPvFsupsbuEhSEVQw9NSt4bVjV2AenXuzMsMW6o3fmC6FK8rEeo7pJY/s1600/fuse_structure.png" /></a></div><br /><span style="color: #0b5394;"><i><span style="font-size: large;"><b>Installation : </b></span></i></span><br /><br />To use FUSE , you must be install this on your system.
