About this fork

This fork attempts to revive lightly with a different approach from boehs, with the assumption that Luwx won't ever resume his project.

This means that this fork allows real changes, and not just maintainence.

The to-do list

• Make a new readme
• Make install work on plasma 6
• Find some more people that can help with this project
• Build some community
• Make some meaningful commits
• Expand to-do list

My plans for changes at the moment -- They are in progress, I'm just really slow

• Redesign the tabbar
  • Fix the issues I caused with it
  • Align it a little better, now it's slightly too left, it needs slightly larger margins for both sides the right side
  • You can now set the old tabbar back if you dont like the new one in the settings
• Make the buttons sligthly larger
  • The standard push button is now slightly larger
  • Spinboxes and comboboxes
  • Now the size of the buttons is adjustable by the user in the settings
• Change the defaults to fit the normal use-cases better
• Add my own colorscheme to it
• Make installation in all major distros easy
  • Can be built on most distros that support plasma 6
• Rename the project to something like „Darkly” to reflect the changes, and for it to be installable alongside the other lightly
• Maintain the project

Installation

Automatic

Thanks to @DeltaCopy, you can use one of these install methods:

Fedora copr

https://copr.fedorainfracloud.org/coprs/deltacopy/lightly-qt6/

AUR

Manual

To ensure this application style works on applications still using QT5 both QT5 and QT6 dependencies are required to be installed before building from source.

Installation script

Note

A script called install.sh is now available which both builds and installs this application style.

./install.sh will remove if existing, build and install Lightly using both QT5/QT6 dependencies.

./install.sh QT5 will build & install using only QT5/KF5 dependencies.

./install.sh QT6 will build & install using only QT6/KF6 dependencies.

./install.sh remove will remove Lightly.

Known issues & solutions

Blurred icon rendering on Wayland with fractional scaling

As referenced in #14

On Wayland when scaling is set to >100% some icons appear blurred.

The fix for now until QT is updated is to add QT_SCALE_FACTOR_ROUNDING_POLICY=RoundPreferFloor into the file /etc/environment

Restart to apply the changes.
