Qt offers a rather wide spectrum of classes for accessing contents of files, including reading and writing bytes to parsing XML, JSon, and CBor files. In addition to that, it also has useful API's for copying files, getting file information (like is it readable), and traversing whole directories. Learn about all that and more in this episode.

Qt comes with a number of container classes. But how do you use them properly, what are the constraints on items you put into them etc. etc.?

Regular expressions is a very powerful tool to parse strings and validate user input. Qt has support for regular expressions via the class QRegularExpression and its helpers.

Qt comes with a string class, as does C++ itself (namely std::string). But in contrast to C++'s string class, Qt's counterpart has lots of powerful utilities built in, which makes it easy to do string operations. Learn all about these in this episode.

In this episode I'll have a look at the tool called pre-commit. It's a tool, as the name suggests, for setting up (and reusing) git pre-commit URLs.

Sometimes a signal fires too often, and, as a result, your user interface feels sluggish. A solution to this is often a timer to compress the signal. In this episode, I'll show you a class from KDToolBox which makes such code easier to read.

Add some colors and some additional information so your QDebug() are more useful and easier to spot.

The class QMainWindow provides all the parts needed to create a main window for your application, namely toolbars, docking widgets, a menu bar, and menus. In this episode, we will look at how they all fit together.

Qt provides built-in dialogs for common use cases including file selection, color/font choosers, simple text input (like asking for names), message display, and progress indication. It also includes a framework for implementing wizards. This episode covers all these dialog types and demonstrates their practical usage in Qt applications.

In Qt, you can create a top level window, simply by providing nullptr as the parent. However, we still have a class called QDialog specifically for creating dialogs. Among other things it offers to wait for the dialog to be completed before your code continues execution.

For agile projects, changes are a daily business, and parts of the project are often defined during the development process. But how to find out how much your project has changed and how to handle this, so you don't miss deadlines?

In this second episode on layout managers, we will discuss how to make widgets stretch, and how to get spaces into your layout. We will discuss that both when you code it in C++, and when you do it in Qt Designer.

Have you ever wondered what the difference is between QWidget::repaint() and QWidget::update()? You may even have heard that update events collapsed into just one event in the event loop, which might make you ask the question on whether there are other events merged together. Let's debug into the Qt source code to get an answer.

The task was simple: Add double click to a push button - with the added bonus of it not emitting the normal clicked if there is a double click. OK, this sounds trivial, right? Well no, it wasn't entirely. To get it right you have to understand quite a bit of both signals/slots and the event system. This episode explains.

LUMA Vision is developing cutting-edge 4D digital imaging (i.e. real time 3D rendering) and navigation to enhance cardiologists' and electrophysiologists' visibility into the heart during intracardiac procedures. With KDAB's support, they are creating it by using Qt to tap into top-notch graphics technology. Watch the video to learn more.

In this last episode on "Show me your IDE", we now look at visual studio code.

This episode of KDAB News includes: Servo for Qt - Interview with Andrew Hayzen and Magnus Groß; Qt 6.7 released; Hotspot 1.5 released; Embedded World 2024 Impressions; Tip of the month - ConnectionEvaluator in KDBindings; Announcements.

In this video, we talk to Aiśwarya Kaitheri Kandoth (Aish) who tells us about the growth of free software in Kerala, India, and of her role in the take-up and evolution of GCompris in schools there.

Complex multi-step processes are not rare when deploying a mature multi-executable application to an embedded target. In the first part of this video, Christoph shows a quick template script that you can use to swiftly deploy multi-app setups to your target. In a the longer, second part, Qt-Creator target configurations are explained in a tutorial. Last, you will learn how nightlies helped not only for development, but post-hoc debugging.

In this video, Christoph demonstrates a high-precision measurement demo utilizing Kistler's highly sensitive sensors to measure force. Kistler, a Swiss company, specializes in crafting top-tier piezoelectric sensors for measuring industry-specific physical parameters like force, acceleration, pressure and mechanical strain.
