THE Microsoft offers a library of interface elements called WinUI: it is designed for those who develop universal applications (UWP), and has been updated to include items with rounded corners, tabbed windows and thinner lines. It is a preview of the design that the Windows 10 should receive in the coming months.
WinUI brings together the interface elements for universal apps: this is an open-source project from Microsoft that reached stable version 2.2 this week. One of its new features is “CornerRadius”: developers can create menus and text boxes with rounded corners.
Zac Bowden, from Windows Central, said on Twitter that the rounded corners should “appear in more areas of Microsoft software in the coming weeks, months and years”, including on Windows, Office and Xbox.
Microsoft Edge with Chromium already uses tabs and text fields with rounded corners. Gradually, Windows 10 and apps like Clima adopt this interface element.
Another new feature of WinUI is the “TabView”: this control allows you to create tabs within an application for different pages or documents. And yes, the flaps have rounded corners.
Windows Terminal already uses this interface element, bringing together the Command Prompt, PowerShell and WSL (Windows Subsystem for Linux) in one tool.
Microsoft canceled a project called Sets that would bring tabs to Windows Explorer (File Explorer) and other programs. This depended on the Edge browser to work, but it will become less integrated with the operating system as it adopts Chromium as a base. Now, with TabView, apps will have the freedom to adopt tabs individually if that makes sense.
Microsoft updates WinUI with “cleaner and more familiar look”
In WinUI, the standard line thickness has been reduced “to a cleaner and more familiar look”, according to Microsoft:
In addition, the look of checkboxes and the radio buttons It has been updated…
… as well as the switch button, which is shorter to stay “visually balanced while maintaining usability”:
These interface elements give an idea of the direction we will see in the design of Windows 10. The system is gradually moving away from the visual flat adopted by Windows 8. WinUI 2.2 is available for developers on GitHub.
Microsoft plans to launch WinUI 3.0 version in 2020: it will bring the same interface standard to traditional Win32 programs and applications on the UWP platform.
