Currently only Windows is supported but hopefully more operating systems will be supported in the future.

Below are screenshots of Cardiograph in action:

How to Convert Unreadable Binary to Readable QString
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.

How to Use Text to Speech in Qt for Windows
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.

Picture Stamper 1.9.3 Released (First Official Release)
I released Picture Stamper officially just moments ago, and for the best possible price, ABSOLUTELY FREE, for anyone who needs a tool such as this. For so long I needed an application to stamp my photos before sharing them on the web but in the end I had no other choice but to write it myself because all options were either too complicated and pricy or they were just not what I needed.

How to find Edges in a Qt QImage
Finding edges is crucial in many image processing applications because it gives a better understanding of the elements in a picture. This post contains download link to an example project (ready to build and run) in Qt that uses nothing but the existing Qt classes, namely QImage, to detect and display edges in a QImage.
