Web developers are quite familiar with Base64 and its usage. To put it simply, whenever to want to store, transfer (send or receive) or do anything else with the contents of a binary file (in this example, an image file) you can use Base64 encoding to simplify things by converting unreadable binary contents to a readable string.

Mouse Hover (Over) Events for Qt Widgets
Qt does not have mouse hover, or mouse over (as some people call it) events in its widgets by default but it provides the means to do it quite easily if you just know how to inherit a class and add some protected functions to it. Here is an example that shows how to create a push button (QPushButton) that reacts to mouse hover events.

There are many APIs on the web that accept JSON requests and reply using JSON. An example for this can be most of Google’s API services. For example if you are writing a Qt application that needs JSON interaction with a Google API (such as Google Webmaster API) you can easily send requests and receive responses if you follow these steps.
Image Filtering Using Fourier Transform
In Machine Vision there is a magical trick that involves Fourier transformation of an image and I would like to share it with you today. I learned this long ago from a professor of mine but I remember back then there was not much experience and information about this on the web. Also there was no program that allowed experimenting with Fourier transformation of Images, until I developed an Android application titled Image Transformer, using OpenCV and Qt, which allows you to do just that.
Embedding Fonts in Your Qt Application
Whether you are building an application or a game using Qt for desktop or mobile, you probably like to see the same fonts on the target computers or phones that you set during development. Well sometimes the fonts that you have used just don’t exist in target platforms. Follow these simple steps to embed a font in your application and guarantee that it will exactly look the same when your users run them.

Unfortunately for Cross-Platform developers, there is no standard method or API that you can code once and use to have TTS (Text to Speech) in your programs. You may find some 3rd party libraries that allow a great deal of reusability in different Operating Systems but at some point they also prove to do less than what you require. Qt has promised to make this available for us in the near feature but it has been postponed all the time. The main reason is that there is a huge race between major Software companies (Microsoft, Google and Apple) in this field and it seems that they somehow make it work in totally different ways on purpose. So anyway that is why I decided to share the method to have TTS in Qt in all well known operating systems and I am going to start with the easiest one, which is Windows.
