Thank you so much for the information.
i am looking forward to perceive my masters in this specific field .
let me if there are any or the related course available in any of the universities .
one last question:
if QStringList images has 10 fileNames, is it possible to access a particular fileName
such as images(5) or images(9)?
i am able to access the first and last fileName with images.first() or images.last() but not the ones which are in between.
But waiting for the solution to set maximum of horizontalslider
If you want to become a really good programmer, you have to acquire an incredible amount of knowledge. Once you can code well, it doesn't make a difference to you what OS you are using. Therefore, there's a contradiction between being a great professional and only knowing how to program for Linux.
If you want to become a pro, go ahead and get a master's degree in Computer Science. If you don't want to do that, read books. Tons of them.
Qt is nice for playing around with typical problems and gaining experience, but it won't help you to understand how the low-level (hardware) or even C++ work. You could buy a C++ book, complete ones are over a thousand pages thick. This is how complicated just C++ is. But when programming C or C++ one should be aware of the hardware, too. Endianness, Caches, Virtual Memory and all this stuff is crucial for efficient programming in lower level languages.
Then, you need to master Software Design. This is the art of bringing your ideas into a shape that you can understand, REALLY understand. People tend to think in chaotic ways (that's how human brains are built) and that's not enough for building a complex program. There are great resources out there for design patterns, and many of them are fun. For example, have a look at https://sourcemaking.com/
One doesn't become a good programmer within three years. It's incredibly tough and evolves super-fast. I am myself in the middle of my CS studies and I get to feel every day how amazingly complex this matter is.
The Interface preferences deal with the “look” of Photoshop CS6. You can change these so that you can use Photoshop in a way that is easiest for you. Here’s the scoop:Screen Modes: In the Color Theme settings, you can choose from four shades of gray for your overall UI. You can also select the color of the background around your image for each screen mode. Finally, you can also select whether your image edge is surrounded by a line, drop shadow, or nothing at all.
@Pro-Grammer I've been learning Qt programming for a while now. The best source of information is (in my opinion) the official documentation you already mentioned (C++ skills are required of course). Qt Assistant is a good tool for browsing the documentation. You can also use the help section of Qt Creator. Additionally there are a lot of useful examples available (you already picked one of them).
