QPushButton *whatsThisButton = new QPushButton(mainGroup) SetWindowTitle(tr( " Affine Transformations")) : QWidget(parent), textEditor( new QLineEdit) XFormWidget::XFormWidget(QWidget *parent) First, add one include directive to import the QElapsedTimer class, which you use to measure the code’s execution time: Start by changing the xform.h file (located inside the Header folder in the project tree on the left side). The main function initializes and displays XFormWidget, in xform.h and xform.cpp. This allows you to measure the performance of these operations when you build the app for 圆4 and AArch64 architectures.Īs with any other C++ app, the application’s entry point is the main function, as defined in main.cpp. This method is responsible for executing affine transformations several times. When you click this button, it invokes the custom runAnimation method. To modify the Affine Transformations app, add one more button with a Run label. Now you can modify this default behavior. It is active when the app runs inside the constructor of the XFormWidget. You can stop the animation by clicking Animate. The app continuously transforms the image of Tux (Linux’s penguin character) by rotating, scaling, and shearing it. Now build and run the app.Īfter execution, the app should look like this: The list of examples should include one project: Affine Transformations.Ĭlick it to make the source code available in Qt Creator. Or you can press F5 to run and debug your project and Ctrl + R to run it without the debugger. The Run and Debug buttons are on the bottom left. Project files are on the left side, and double-clicking them opens them in the editor. If you are new to Qt Creator, consult the documentation for a quick introduction. This means you don’t need to learn any new skills to develop apps for WoA.Īfter installation, open Qt Creator, click Examples, select Qt6, and type “affine” in the search box. Note that Windows Dev Kit 2023 runs the full version of Windows 11, so the installation and development processes are the same as on a typical desktop. ![]() In the Qt Setup window, select at least Qt version 6.2. Or if you do not want to register, go to the Qt for Open Source Development page and download from there. To begin development, go to the Qt Group download page, register for the Qt trial, and download Qt. But you can also get a similar performance boost on Mac computers with Apple silicon chips running Windows 11 (for example, by using Parallels Desktop). This tutorial uses the Windows Dev Kit 2023 (also called Project Volterra) for development. Moreover, AArch64 is now fully supported on Windows 11 by Arm64EC. AArch64 provides high performance with low energy requirements, making it ideal for apps on edge devices. As more complex AI models move to edge devices, the demand for the efficiency of those devices continues to increase. You can also use Qt to create intelligent edge devices. This means you can use it to target many platforms simultaneously. Qt provides cross-platform app development, so you can use the same high-level APIs to create apps that run on desktop, mobile, and Internet of things (IoT) devices with zero or minimal platform-specific code. As a result, you can fully leverage device hardware to accelerate your graphical user interface (GUI)-based applications. Qt enables you to build your software for either 圆4 or AArch64 processor architectures. Qt v6.2 now supports native development for WoA, so you can download the installers from the official website. Qt is an application development framework for desktop, embedded, and mobile platforms. Then, this tutorial shows you how to reduce the computation time of the 圆4 architecture by 40 percent by making simple changes. They include image rotation, scaling, and shearing, which are commonly used by AI-powered machine vision systems. The transformations demonstrate the performance boost the AArch64 architecture provides. To demonstrate the advantages of native development, this article shows you how to perform affine transformations on graphic images. Qt v6.2 now supports native development for Windows on Arm (WoA). Qt also provides development tools, including Qt Creator, a cross-platform integrated development environment (IDE). Thanks to its widget toolkit, all apps created with Qt have a native-looking user interface (UI). Qt enables you to develop maintainable, highly performant, and reusable code. The Qt Framework (Qt) provides modularized C++ library classes and application programming interfaces (APIs) to accelerate cross-platform application development. ![]()
