Native GTK Dialogs in LibreOffice

Filed under
LibO

The LibreOffice UI was traditionally implemented with its own VCL toolkit which via theming emulated the host desktop toolkit.

Then we migrated the file format the dialogs were described in to the GtkBuilder file format. But still implemented with VCL widgetry, though with additional GTK-alike layout widgets.

Then migrated the translation format to gettext .mo files, which added plural form translation support we had lacked.

Then incrementally migrated the code driving the dialogs to a new API with two implementations, one for VCL widgetry and one for GTK.

Over the last few major releases the GTK version of LibreOffice has increasingly had true GTK dialogs and less VCL dialogs and in master, as of this week, there are now no direct uses of the VCL dialog APIs.

LibreOffice 6.4 Will Ship With Native GTK Dialogs on Linux

  • LibreOffice 6.4 Will Ship With Native GTK Dialogs on Linux

    For the past few years developers working on the open source productivity suite have been busy porting LibreOffice’s many (many) dialogs from VCL (a cross platform UI toolkit) to GTK.

    That work has come along nicely, with recent versions of LibreOffice for Linux sporting a mix of VCL message dialogs (with GTK theming applied where possible) and native GTK dialogs.

    But the GTK dialog effort just hit a major milestone.

    In an update posted on his blog, LibreOffice developer Caolán McNamara explains that: “over the last few major releases the GTK version of LibreOffice has increasingly had true GTK dialogs and less VCL dialogs and in master.”

    And, he adds that as of this week:“there are now no direct uses of the VCL dialog APIs”.

Security: Updates, Mozilla AMO and Reproducible Arch Linux Packages

  • Security updates for Monday

    Security updates have been issued by Debian (ampache, chromium, djvulibre, firefox-esr, gdal, and ruby-haml), Fedora (chromium, file, gd, hostapd, nspr, and rssh), openSUSE (bcm20702a1-firmware, firefox, gdal, libtomcrypt, php7, python-ecdsa, python3, samba, and thunderbird), SUSE (apache2-mod_auth_openidc, libssh2_org, and rsyslog), and Ubuntu (bash).

  • Security improvements in AMO upload tools

    We are making some changes to the submission flow for all add-ons (both AMO- and self-hosted) to improve our ability to detect malicious activity. These changes, which will go into effect later this month, will introduce a small delay in automatic approval for all submissions. The delay can be as short as a few minutes, but may take longer depending on the add-on file. If you use a version of web-ext older than 3.2.1, or a custom script that connects to AMO’s upload API, this new delay in automatic approval will likely cause a timeout error. This does not mean your upload failed; the submission will still go through and be approved shortly after the timeout notification. Your experience using these tools should remain the same otherwise.

  • Reproducible Arch Linux Packages

    Arch Linux has been involved with the reproducible builds efforts since 2016. The goal is to achieve deterministic building of software packages to enhance the security of the distribution. After almost 3 years of continued effort, along with the release of pacman 5.2 and contributions from a lot of people, we are finally able to reproduce packages distributed by Arch Linux! This enables users to build packages and compare them with the ones distributed by the Arch Linux team. Users can independently verify the work done by our packagers, and figure out if malicious code has been included in the pristine source during the build, which in turns enhances the overall supply chain security. We are one of the first binary distributions that has achieved this, and can provide tooling down to users. That was the TL;DR! The rest of the blog post will explain the reproducible builds efforts, and the technical work that has gone into achieving this.

  • Arch Linux Updates Its Kernel Installation Handling

    Arch Linux has updated the behavior when installing the linux, linux-lts, linux-zen, and linux-hardened kernel options on this popular distribution.  The actual kernel images for their official Linux, Linux LTS, Linux Zen, and Linux Hardened flavors will no longer be installed to /boot by default. By not having the actual kernel reside on /boot should help those with separate boot partitions that are quite small and avoid running out of space when keeping multiple kernels installed.

The Many Features & Improvements of the KDE Plasma 5.18 LTS Desktop Environment

With the KDE Plasma 5.17 release out the door last month, it's time to take a closer look at the new features and improvements coming to KDE Plasma 5.18, which will be released early next year as the next LTS (Long Term Support) version of open-source desktop environment designed to run on GNU/Linux distributions. Among the enhancements of the KDE Plasma 5.18 LTS desktop environment, we can mention the ability to select and remove multiple Bluetooth devices simultaneously, support for KSysGuard to display stats for Nvidia graphics hardware, and a new "Home" button in System Settings that will take users back to the main page.

Open-spec, dual-port router offers a choice of Allwinner H3 or H5

FriendlyElec’s Linux-driven, $20 “NanoPi R1S-H3” router uses a modified version of the Allwinner H3-based NanoPi R1, upgrading the second LAN port to GbE while removing a USB port. There’s also a similar, $23 “NanoPi R1S-H5” with a quad -A53 H5. Back in February, FriendlyElec launched the community-backed NanoPi R1 router SBC, which still sells for $29. Now it has followed up with two more affordable NanoPi R1S routers based on upgraded versions of the NanoPi R1 that that give you dual GbE ports instead of 10/100Mbps and 10/1000/1000Mbps. The mainboards are smaller than the R1 at 55.6 x 52mm, and the board and the case have been entirely redesigned. Read more
