MauiKit 4 Frameworks & Apps

With the previous version released, MauiKit Frameworks and Maui Apps were ported over to Qt6, however, some regressions were introduced and those bugs have now been fixed with this new revision version.

Currently, there are over 10 frameworks, with two new ones recently introduced. They all, for the most part, have been fully documented, and although, the KDE doxygen agent has some minor issues when publishing some parts, you can find the documentation online at https://api.kde.org/mauikit/ (and if you find missing parts, confusing bits, or overall sections to improve – you can open a ticket at any of the framework repos and it shall be fixed shortly after)

A brief list of changes and fixes introduced to the frameworks are the following:

For MauiKit Controls

• MauiKit is now no longer dependent on MauiKit-Style, so any other QQC2 style can be used with Maui Apps (other styles are not supported).
• MauiKit documentation has been updated with notes on the new attached controls properties – https://api.kde.org/mauikit/mauikit/html/classControls.html
• MauiKit fixes the toast area notifications. The toast notifications can now take multiple contextual actions.
• MauiKit Demo app has been updated to showcase all the new control properties
• New controls: TextField, Popup, DropDownIndicator,
• MauiKit fixes the template delegates and the IconItem control
• MauiKit fixes to the Page autohide toolbars
• Update style and custom controls to use MauiKit Controls’ attached properties for level, status, title, etc.
• Display keyboard shortcut info in the MenuItems
• Update MauiKit Handy properties for isMobile, isTouch, and hasTransientTouchInput and fixes to the lasso selection on touch displays
• Added more resize areas to the BaseWindow type
• Check for system color scheme style changes and update accordingly. This works on other systems besides Plasma or Maui, such as Gnome or Android
• The type AppsView has been renamed to SwipeView, and AppViewLoader to SwipeViewLoader
• Update MauiKit-Style to support MauiKit Controls attached properties and respect the flat properties in buttons
• Fixes to the MauiKit bug in the GridBrowser scrollbars policy
• Fixes to the action buttons layout in Dialog and PopupPage controls
• Refresh the icon when a system icon-theme change is detected – a workaround for Plasma is used and for other systems the default Qt API

For the MauiKit Frameworks

• FileBrowsing fixes bugs with the Tagging components
• Fixes to the models using dates. Due to a bug in Qt getting a file date time is too slow unless the UTC timezone is specified
• Update FileBrowsing controls to use the latest Mauikit changes
• Added a new control: FavButton, to mark files as favorites using the Tagging component quickly
• Update and fixes to the regressions in the other frameworks
• ImageTools fixes the OCR page
• TextEditor fixes the line numbers implementation.

All of the frameworks are now at version 4.0.1

All of the apps have been reviewed for the regressions previously introduced in the porting to Qt6; those issues have been solved and a few new features have been added, such as:

• Station, now allows opening selected links externally
• Index fixes to the file previewer and support for quickly tagging files from the previewer
• Vvave fixes to the minimode window closing
• Update the apps to remove usage of the Qt5Compat effects module
• Fix issues in Fiery, Strike, and Agenda
• Fix the issue of selecting multiple items in the apps not working
• Clip fixes to the video thumbnail previews and the opening file dialog
• Implement the floating viewer for Pix, Vvave, Shelf, and Clip for consistency
• Correctly open the Station terminal at the current working directory when invoked externally
• Among many few other details

** Index, Vvave, Pix, Nota, Buho, Station, Shelf, Clip, and Communicator versions have been bumped to 4.0.1

*** Strike and Fiery browser versions have been bumped to 2.0.1

**** Agenda and Arca versions have been bumped to 1.0.1

And as for Bonsai, Era, and other applications still under development, there is still not a ported version to Qt6 as of now

 

Maui Shell

Although Maui Shell has been ported over to Qt6 and is working with the latest MauiKit4, a lot of pending issues are still present and being worked on. The next release will be dedicated fully on Maui Shell and all of its subprojects, such as Maui Settings, Maui Core, CaskServer, etc.

That’s it for now. Until the next blog post, that will be a bit closer to the 4.0.1 stable release.

Make integrations with other services more resilient using a Queue Anonymous (not verified) Wed, 12/18/2024 - 07:00 Tags Web Development Drupal Drupal Planet reliability

• Read more about Make integrations with other services more resilient using a Queue
• Add new comment

One downside of automating things is dealing with outages. Sometimes services go down, and are not available for some period of time. When this happens, how does it impact your automation?

If you don't design your automation carefully, you might lose the data entirely. Or get spammed by hundreds of submissions when it comes back up. Handling this correctly does end up needing some understanding of how the automation works, as well as any quirks of the remote system.

Django user management allows you to integrate user authentication and management into your web applications. By using Django, you can leverage the framework’s built-in authentication system to manage user registration, login, and logout. With just a few additional templates, you can enable users to reset and change their passwords independently.

This tutorial guides you through setting up a basic user management system with Django that you can extend later. You’ll learn how to create a dashboard, implement user registration, and connect authentication URLs, as well as customize templates for login, logout, and password management.

By the end of this tutorial, you’ll understand that:

• Django’s user authentication is a built-in authentication system that comes with pre-configured URLs and views.
• Authentication verifies user identity, while authorization determines user permissions within Django.
• Registering as a user in Django requires setting up views, templates, and URLs.
• Creating a login system in Django involves built-in authentication views and creating custom templates.
• Resetting passwords in Django involves configuring email backends for sending reset links.

This tutorial focuses on user authentication and user management. If you want to learn more about permissions and groups, then you can check out the tutorial about managing users in Django’s admin site.

Get Your Code: Click here to download the free sample code you’ll use to set up a basic user management system with Django .

Start With the Basics

For bigger projects, you may consider creating a custom user model. In this tutorial, you’ll be using Django’s built-in user model. This is a great place to start to familiarize yourself with user authentication in general.

In this section of the tutorial, you’ll first create a small Django project with a users app. Then, you’ll make some adjustments to Django’s password validator to make your development more convenient. Finally, you’ll create an admin user to verify your setup.

Set Up the Django Project

It’s a good idea to use a virtual environment when working with Python projects. That way, you can always be sure that the python command points to the right version of Python and that the modules required by your project have the correct versions. To read more about creating virtual environments, check out Python Virtual Environments: A Primer.

Select your operating system below and use your platform-specific command to set up a virtual environment:

• Windows
• Linux + macOS

Windows PowerShell PS> python -m venv venv\ PS> .\venv\Scripts\activate (venv) PS> Copied! Shell $ python -m venv venv/ $ source venv/bin/activate (venv) $ Copied!

With the above commands, you create and activate a virtual environment named venv by using Python’s built-in venv module. The parenthesized (venv) in front of the prompt indicate that you’ve successfully activated the virtual environment.

Now that the environment is ready, you can install Django, start a new project, and create an application to store all your user management code:

Shell (venv) $ python -m pip install Django (venv) $ django-admin startproject user_auth_intro (venv) $ cd user_auth_intro (venv) $ python manage.py startapp users Copied!

In this example, you name your project user_auth_intro and your application users. To include the users app in your Django project, you need to add a reference to the app’s configuration class at the beginning of the INSTALLED_APPS list in settings.py:

Python user_auth_intro/settings.py 1# ... 2 3INSTALLED_APPS = [ 4 "users.apps.UsersConfig", 5 "django.contrib.admin", 6 "django.contrib.auth", 7 "django.contrib.contenttypes", 8 "django.contrib.sessions", 9 "django.contrib.messages", 10 "django.contrib.staticfiles", 11] 12 13# ... Copied!

By adding users.apps.UsersConfig, you let Django know that the users app you just created exists. If you have a look at the INSTALLED_APPS list, then you’ll spot Django’s default authentication system on line 6. In django.contrib.auth, Django stores the core of its authentication framework and the default models that you’ll build on later.

Next, apply the migrations and run the Django development server:

Shell (venv) $ python manage.py migrate (venv) $ python manage.py runserver Copied!

These commands create all default models in the database and start the Django development server.

Deactivate the Password Validator

By default, Django enforces strong passwords to make user accounts less prone to attacks. Since you’ll need to change passwords often throughout this tutorial, figuring out a strong password each time would be inconvenient.

Drupal Advent Calendar day 18 - Content Publishing Workflows james Wed, 12/18/2024 - 09:00

Welcome back for day 18, as we enter the last week to the big day - I mean the arrival of Father Christmas, not the launch of Drupal CMS!

Today we are looking at publishing workflows in Drupal CMS. 

Something that many content management systems have offered out-of-the-box is the ability to specify a date and time when a piece of content will be published. This has also been available in Drupal for a very long time, but has always required installation of extra modules - until now.

With Drupal CMS, every content type created by the base install, and any recipes within Drupal CMS, automatically…

Alex Moreno shares his personal experience from DrupalCon Singapore 2024, offering insights on AI-driven Drupal innovations, the upcoming Experience Builder release, and the growing momentum in Asia’s Drupal market. From roundtable discussions to contribution highlights, get an inside look at the key moments shaping Drupal’s future.

This release fixes AI Chat to continue to work after OpenAI drops v1 API support this month, uses the configured AI model also for AI Chat, fixes the debugger to work when two or more versions of Python are loaded into a process, improves OpenAI Assistant, File, and Vector Store resource management, reduces debugger stack space usage, fixes using ${WING:PROJECT_DIR} and other environment variable references in a Python File OS Commands, and fixes several other minor usage issues.

See the change log for details.

Important Note: Users of the AI Chat beta in Wing version 10.0.7.1 and earlier may find many untitled Vector Stores in their OpenAI account, which were left as a side effect of Wing's earlier use of the beta Assistants API. OpenAI may start charging for these or other resources in your OpenAI account at the end of 2024. These resources can be removed by invoking internal-ai-delete-resources(untitled_vector_stores=True) from the Edit > Command by Name menu. This runs in the background, may take several minutes to finish, and will be terminated if Wing is quit before it completes. Use caution if you have other applications that call OpenAI's Assistants API, as this cannot distinguish the Vector Stores created by Wing and other applications. Once resources have been deleted, you will need to restart all instances of Wing before AI Chat will work again. Afterward, you should not see any further accumulation of Vector Stores or other resources in your OpenAI account, other than those that are actively in use. However, please note that Wing's AI Chat is based on API that is still being flagged as 'beta' by OpenAI.

What's New in Wing 10

AI Assisted Development

Wing Pro 10 takes advantage of recent advances in the capabilities of generative AI to provide powerful AI assisted development, including AI code suggestion, AI driven code refactoring, description-driven development, and AI chat. You can ask Wing to use AI to (1) implement missing code at the current input position, (2) refactor, enhance, or extend existing code by describing the changes that you want to make, (3) write new code from a description of its functionality and design, or (4) chat in order to work through understanding and making changes to code.

Examples of requests you can make include:

"Add a docstring to this method" "Create unit tests for class SearchEngine" "Add a phone number field to the Person class" "Clean up this code" "Convert this into a Python generator" "Create an RPC server that exposes all the public methods in class BuildingManager" "Change this method to wait asynchronously for data and return the result with a callback" "Rewrite this threaded code to instead run asynchronously"

Yes, really!

Your role changes to one of directing an intelligent assistant capable of completing a wide range of programming tasks in relatively short periods of time. Instead of typing out code by hand every step of the way, you are essentially directing someone else to work through the details of manageable steps in the software development process.

Boost is a very large and comprehensive set of (peer-reviewed) libraries for the C++ programming language, containing well over one hundred individual libraries. The BH package provides a sizeable subset of header-only libraries for (easier, no linking required) use by R. It is fairly widely used: the (partial) CRAN mirror logs (aggregated from the cloud mirrors) show over 38.5 million package downloads.

Version 1.87.0 of Boost was released last week following the regular Boost release schedule of April, August and December releases. As before, we packaged it almost immediately and started testing following our annual update cycle which strives to balance being close enough to upstream and not stressing CRAN and the user base too much. The reverse depends check revealed six packages requiring changes or adjustments. We opened issue #103 to coordinate the issue (just as we did in previous years). Our sincere thanks to Matt Fidler who fixed two packages pretty much immediately.

As I had not heard back from the other maintainers since filing the issue, I uploaded the package to CRAN suggesting that the coming winter break may be a good opportunity for the four other packages to catch up. CRAN concurred, and 1.87.0-1 is now available there.

There are no other changes apart from cosmetics in the DESCRIPTION file. For once, we did not add any new Boost libraries. The short NEWS entry follows.

Changes in version 1.87.0-1 (2024-12-17)

• Upgrade to Boost 1.87.0, patched as usual to comment-out diagnostic suppression messages per the request of CRAN

• Switched to Authors@R

Via my CRANberries, there is a diffstat report relative to the previous release. Comments and suggestions about BH are welcome via the issue tracker at the GitHub repo.

Automatically update a spreadsheet of active products Anonymous (not verified) Tue, 12/17/2024 - 07:00 Tags Drupal Website management E-Commerce Drupal Planet

• Read more about Automatically update a spreadsheet of active products
• Add new comment

One of our e-commerce clients has several thousand active products. As a distributor, their clients are retailers, some of which like having an up-to-date product spreadsheet.

Using the Events, Conditions, and Actions (ECA) module along with a Views Data Export view of all products, we created a view of all the relevant fields that exports a spreadsheet of all their products, and saves it in their private media system once per day.

Sockets and the socket API are used to send messages across a network. They provide a form of inter-process communication (IPC). The network can be a logical, local network to the computer, or one that’s physically connected to an external network with its own connections to other networks. The obvious example is the Internet, which you connect to via your ISP.

In this video course, you’ll create:

• A simple socket server and client
• An improved version that handles multiple connections simultaneously
• A server-client application that functions like a full-fledged socket application, complete with its own custom header and content

Qt 6.9 brings some useful new features to improve the development process for developers targeting the Android platform. Keep in mind that the following list is not exhaustive of all changes around Qt for Android, and some other features might get their own blog.

Support for Uncompressed Native Libraries

Android 6 and above produces uncompressed native libraries that are only part of the APK by default. However, Qt had this behavior explicitly disabled with the following setting under build.gradle:

android {
...
   packagingOptions.jniLibs.useLegacyPackaging true
...
}

Or via the now deprecated extractNativeLibs manifest flag, because Qt didn't support loading libraries directly from the APK. With this release, such support for reading and loading shared libraries directly from the APK without having them extracted to disk but rather, map those shared libraries to memory. Qt apps and APIs such as QLibrary and QPluginLoader should work the same as before and iterate libraries under the native libraries' directory.

There are few things to consider when this mode is enabled (it's enabled by default on 6.9+). For example, QCoreApplication::applicationDirPath() would now return a path that points to a shared library filename that's inside the app's APK, usually in the form:

/data/data/package-path/base.apk!/lib/arm64-v8a/libmyapp_arm64_v8a.so

Paths returned by similar API calls might have previously returned a writable path, after this however, the returned paths won't be writable.

Enabling this might increase slightly the total size of produced APKs, but saves on disk space after installation and also on update sizes from the Play Store and slightly faster startups. For more information, see Improvements for smaller app downloads on Google Play.

Apps with the older way using compressed libraries still work as before if the relevant flag is explicitly enabled as mentioned above.

New Command-Line App/Test Runner

When developing for Android, you're expected for the most part to be using an IDE that handles the build and deployment and running the app. That process doesn't need to be that complicated, because of that we've added wrapper scripts that handle that job for you. Especially, on CI environments or if you're one of the people who can get by using a lightweight code editor and a terminal for development, this can be quite handy for you. All you need to do is build your project's APK and run the app as follows:

cd build
qt-cmake -S .. -B . -GNinja
cmake --build . --target apk
MY_ENV_VAR=value ./my_app --install --my_arg value

This last command would handle all the underlying adb commands behind the scenes by installing the app to the device, starting it and printing the logcat of the app, making it a more seamless experience and hassle free. For Windows, the runner has the .bat file extension.

You can pass environment variables directly from your shell so they end up being passed to the app's runtime on the device. The same applies for command line arguments, where arguments not reserved by the runner are passed as app's arguments. For all parameters that the wrapper accepts, call it with --help.

The same applies for auto tests, you would be able to simply do the following:

cd build
QTEST_FUNCTION_TIMEOUT=900000 ./tst_android test_case_1

And that would simply handle everything with androidtestrunner under the hood. In this case, you don't need to manually issue the APK build command because androidtestrunner takes care of that.

CMake Android APIs

We keep improving the integration of Android builds with CMake to make it easier to manage and maintain Android-specific requirements. Here’s what’s new:

Add App Permissions

Managing permissions for Android apps often requires manual edits to the AndroidManifest.xml. The newqt_add_android_permission() function removes this hassle by letting you declare permissions directly within your CMakeLists file. This function still allows auto inclusion of Qt modules' managed permissions. This approach simplifies project management, making it more straightforward by keeping project configurations in one place.

Setting an App's Name and Icon

Setting the app's name is now as simple as specifying it with QT_ANDROID_APP_NAME in your CMake configuration. No more manual setting of the app's name in the AndroidManifest.xml file. Similarly, you can now define your app's icon drawable/mipmap in your project's CMake configuration with QT_ANDROID_APP_ICON. This expects the icon drawables to be under the appropriate Android resource directory hierarchy and the use of QT_ANDROID_PACKAGE_SOURCE_DIR.

Setting Java/Kotlin Compile SDK Level

The new property QT_ANDROID_COMPILE_SDK_VERSION allows you to specify the Android SDK version for compiling Java code. With this property, you can ensure your project is always built against the desired API level.

Improved Background Event Management

Background processes, particularly those involving UI updates, can be a source of performance bottlenecks if not managed properly. To address this, now it's possible for developers to set a maximum limit for queued background UI events by setting the new environment variable QT_ANDROID_BACKGROUND_ACTIONS_QUEUE_SIZE.

This enhancement prevents potential memory overload caused by an excessive number of tasks waiting in the queue. By defining a limit, developers can ensure smoother performance and prevent lagging or unresponsive behavior in their apps.

That's all from me this time! As always, we continue to improve Qt for Android, and we welcome your feedback and suggestions on this blog post or over bugreports.qt.io.
