Introduction to qView

qView is born with a clear objective to be a practical and minimalist image viewer. That is to say that we will only have the image as the central protagonist and without even a menu bar, it’s just you and the image. It is created with QT technology and is OpenSource which allows us to verify the source code of the application.

About this the developers say

qView was designed from the very start to be as visually minimal and space-efficient as possible. No cluttered interface, just your image, and a title bar.

This makes it a very light and easy-to-use application on our system. It has proven that its load times are quite short and the use of computer resources is quite low.

Despite being so light and having a minimalist graphical interface, it is not lacking in features such as rotating, flipping, zooming, opening images from a URL, recent images, from another location. All of them can be accessed by right-clicking on the main interface.

And what about supported formats? Don’t worry about that because qView supports all common image formats including bmp, gif, jpg, png, tiff, and webp.

Install qView on Linux

The support provided by this application is great and there are many options available to install it.

For Ubuntu 20.04/ 18.04 as well as any distribution based on any of these versions, we have available a PPA:

sudo add-apt-repository ppa:jurplel/qview
sudo apt update

And finally, install the application:

sudo apt install qview

For Debian 10, we have to download a DEB file from the download site or by running

https://github.com/jurplel/qView/releases/download/4.0/qview_4.0-2_amd64.deb

And install it by running

sudo apt install ./qview_4.0-2_amd64.deb

Every time a new stable version is released, you will have to update the command.

For ArchLinux it is available from AUR.

For OpenSUSE you can run

sudo zypper in qview

In the case of any RPM package based distribution, you can download the package

wget -c https://github.com/jurplel/qView/releases/download/4.0/qview_4.0-2_amd64.deb

and install it with your distribution’s package manager.

Finally, you can download the APPImage format which is compatible with any Linux distribution. For many, it is the best way-

wget -c https://github.com/jurplel/qView/releases/download/4.0/qView-4.0-x86_64.AppImage

Conclusion

qView is an application whose main concept is minimalism but without losing functionality. Thanks to it we have an alternative to other image viewers more complex to use.

QTCreator a perfect IDE for QT

QT is a framework of libraries to make graphical user interfaces. It is thought in the beauty and uniformity of the elements, as well as in the correct execution of the same ones. Many large applications use QT, such as the Plasma desktop environment and its applications. But also, applications known as VLC use it.

There is no better way to take advantage of QT than by using QTCreator. QTCreator is a lightweight, open-source framework that integrates seamlessly with many QT developer needs. It is also designed to make C++ development of the Qt application faster and easier. It has many features you have to look.

Since its conception, QTCreator does not intend to rival other IDEs like Eclipse or Netbeans, but on the contrary to serve as a gateway to QT development.

QTCreator is related to C++ development but supports other programming languages such as Python and C#.

So let’s start installing QTCreator on Ubuntu.

Install QTCreator on Ubuntu 20.04 / 18.04

Basically, there are two ways to install QTCreator on Ubuntu 20.04/ 18.04. The first is through the main distribution repositories. If we want to develop calmly sacrificing a little the new features of each version, the ideal is to choose this method.

So, open a terminal and run the following:

:~$ sudo apt install qtcreator

Of course, that is the only way to install the IDE, but if we do not install the necessary libraries and compilers, it will not do us any good. So, install them.

:~$ sudo apt install build-essential

If you have multiple versions of Qt, you probably want 5 to be the default QTCreator version to use. To do this, install the following package.

:~$ sudo apt install qt5-default

Then we can begin to develop. However, it is convenient to install the QT documentation and its examples to help the development.

:~$ sudo apt install qt5-doc qt5-doc-html qtbase5-doc-html qtbase5-examples

Now you can start QTCreator and start working.

On the contrary, if you want a more updated version of QTCreator or QT. Go to the QT website and download the online installer.

Once downloaded, assign it execution permission and execute it by double-clicking on it.

:~$ chmod +x [file_path]

Just follow the instruction and then, you will have to choose what to install.

After configuring other small things like the installation location, you can start the download process.

Finally, launch it.

Conclusion

QT is a great graphic library for your modern applications. But behind a great library, there is a great IDE. In this case, QTCreator is quite good and ideal for developing applications that use QT. And in this post, you have learned how to install it.
