In this post I’m sharing the pre-built libraries and binaries for OpenCV that I use to build Qt/QML and OpenCV powered apps for Android (armeabi-v7a) phones. An example of such application is Quick-Camera-CV which I shared its source codes in a previous post.
I have avoided using QML for long time and always wrote even the most simple applications using Qt Widgets and C++ code but the release of Qt’s Quick Controls 2 and Material Style just made it very irresistible and I had to go for it. Well it didn’t take too long to get a hold of things […]
This one is taken from one of my favourite books (OpenGL 4.0 Shading Language Cookbook) and the relevant chapter’s title for this tutorial in the book is called “Implementing diffuse, per-vertex shading with a single point light source”. Of course it’s modified to use OpenGL ES in Qt which is more cross-platform and creates less […]
First of all let’s briefly go through what’s an OBJ File. Here’s a very brief description from Wikipedia: “OBJ (or .OBJ) is a geometry definition file format first developed by Wavefront Technologies for its Advanced Visualizer animation package. The file format is open and has been adopted by other 3D graphics application vendors.” Anyway, I’ll […]
If you’re a regular Qt user (like me) and have tried writing Android applications with Qt then you must have come across situations where you’ve needed some very simple capabilities of Android API but it wasn’t present in the Qt library. Displaying a Toast message in Qt for Android is one of those situations. In […]
I have tried numerous methods to get an application’s own version number and believe me this is the best way to get it. First of all if we consider the fact that setting a Qt application version is done in PRO file (qmake) using the following simple command: VERSION = 22.214.171.124 Then getting this same […]
When using Qt creator following error starts rising up when Xcode gets updated to version 8.0 and it’s because of a change that is not yet applied in Qt settings. In my case it happened with Qt 5.7 and Xcode 8.0 on Mac OS X El Capitan but I think it’s safe to assume similar […]
By default Qt does not copy fonts along with your application when you deploy them under Linux. I recently faced this issue and none of the texts or labels on my Qt windows showed anything on them. All labels and text were blank and the forms looked completely empty.
In this post I’ll describe how to reset the changes and discard whatever you have done (maybe you decided the changes weren’t required at all) using Git in Qt Creator. If you already know how to install Git and use it with Qt Creator then continue reading, if not then you should first read this […]
Git is one of the most popular version control systems and Qt Creator provide very intuitive and easy to use tools to interact with Git and skip all the command-typing that is required by Git. I think it is safe to assume that you already know how to get Git (https://git-scm.com/). If Git is already […]
