Maui Report 14 3 years ago

Today, we bring you a new report on the Maui Project’s progress.

The stable release scheduled just a few weeks away will be the last progress report listing essential changes. The following blog post will announce the stable release, including only necessary bug fixes to issues and regressions found in this short Beta stage. This cycle introduces new components to the frameworks and paper-cut fixes to the group of applications, shaping a better convergent experience.

What’s new?

Beta APK packages are available for comprehensive testing with this post, so if you feel adventurous, you can install them on your Android device. If you find issues, bugs, or have feature requests, you can open and fill a ticket to the corresponding Invent repository.

MauiKit 2

MauiKit is a group of frameworks that help to build convergent applications quickly. It has a Core component with a set of convergent-ready UI controls that expand on QQC2 and Kirigami; a group of more feature-rich controls like ‘FileBrowser,’ an I’mageViewer,’ and a ‘TextEditor.’ And back-end tools to help you develop and integrate the application in different platforms and form factors. All of these components are actively in use by the group of default Maui Apps.

Once again, the framework has been clean up, and many bugs have were solved, resulting in better performance and optimizations.


  • New Notify component to send native system notifications; with it, you can also set a list of actions right from QML by using NotifyAction. Now it makes use of the KNotification library.
  • Flatter and lighter-styled controls with Maui-Style (being used in AppImages and other platforms than Linux)
  • CSD (Client-Side Decorations) no longer depends on libappletdeco. Instead, the CSD Window control buttons are MauiKit assets; we will improve this in later iterations at least it won’t break with every new KWindowDeco2 release.
  • KConfig is now a private dependency, and other apps linking to MauiKit::Core no longer need to ‘link’ to it.


  • We refactored the Holder control. The Holder control is a message placeholder image or text.
  • The convergent ContextualMenu now can also list QQC2 Actions correctly.
  • We refactored the SelectionBar control. The container listing the selected files is now a proper Popup.
  • New ComboBox control that makes use of the ContextualMenu Popup UI.
  • The Dialog control default buttons are more cohesive with the lighter and border-less styles in other UI elements.
  • The ToolActions control, which groups together Actions into joined buttons, now has sharped rounded corners.


  • Now has its image assets for use as a placeholder, for example, in the TagsDialog.
  • Fixed Downloader arithmetic expression causing segfaults.
  • The PlacesList model was cleanup, removing unneeded methods.
  • The FileBrowser control grid view now maps the icon sizes to static and optimized dimensions: 22, 32, 48, 64, or 128.
  • The KIO dependency is private, and other apps linking to MauiKit:FileBrowsing no longer need to ‘link’ to it.
  • We cleaned up the FileDialog control.
  • New keyboard-based shortcut: Now, you can select all files between two items by clicking Shift+Left Click.


  • Added a new function to the TextEditor control goToLine(int line)
  • Private dependencies cleanup.
  • We continue to work on fixing the line numbers.


  • Private dependencies cleanup, Qt5::Sql is now a private dependency.
  • Fixed the installation of the cities database in Android for GPS location tagging.

Maui Apps

For the upcoming 2.0 stable release, most of the apps are now much faster and stable. Sol, Booth, and Strike are still in the Alpha stage and will not have public releases until 2.1 or 2.2.

Index The file manager has a lighter interface, but it is still as feature-rich as before, with support for previewing files like fonts, compressed archives, PDFs, videos, and music. Also, it supports compression and extraction of file archives, a recent files overview, and powerful selection tools. Oh, and tabs, split views, and embedded terminal. 🙂 This upcoming release has also gained more keyboard shortcuts, making it a viable option for computers.

  • We fixed issues with the extraction of compressed archives.
  • We moved the View options to the view tool-button menu.
  • We fixed some File previewers issues; for example, the Audio Previewer is now more straightforward, and the Fonts previewer showcases the font file weights much more clearly.
  • The places sidebar now has a placeholder when there are no bookmark locations.
  • The View options groups for sort order now work correctly. Having different auto exclusive groups into a single menu is not well supported by QML yet.
  • We have updated the Android Manifest file.
  • Cleanup dependencies.
  • We use notifications when a file archive extraction is successful; this uses the new MauiKit::Core Notify controls!.
  • PathList model refactored.
