Say hi to cuttlefish!

Cuttlefish icon previewer

One of the things I’ve been sorely missing when doing UI design and development was a good way to preview icons. The icon picker which is shipped with KDE Frameworks is quite nice, but for development purposes it lacks a couple of handy features that allow previewing and picking icons based on how they’re rendered.

Over the christmas downtime, I found some spare cycles to sit down and hammer out a basic tool which allows me to streamline that workflow. In the course of writing this little tool, I realised that it’s not only useful for a developer (like me), but also for artists and designers who often work on or with icons. I decided to target these two groups (UI developers and designers) and try to streamline this tool as good as possible for their usecases.

Cuttlefish is the result of that work. It’s a small tool to list, pick and preview icons. It tries to follow the way we render icons in Plasma UIs as close as possible, in order to make the previews as realistic as possible. I have just shown this little tool to a bunch of fellow Plasma hackers here at the sprint, and it was very well received. I’ve collected a few suggestions what to improve, and of course, cuttlefish being brand-new, it still has a few rough edges.

You can get the source code using the following command:

git clone kde:scratch/sebas/cuttlefish
git clone kde:plasmate

and build it with the cmake.

Enjoy cuttlefish!

[Edit] We moved cuttlefish to the Plasmate repository, it’s now part of Plasma’s SDK.

“Killing the Cashew” done right.

Plasma Desktop's Toolbox
Plasma Desktop’s Toolbox
One of the important design cornerstones of Plasma is that we want to reduce the amount of “hidden features” as much as possible. We do not want to have to rely on the user knowing where to right-click in case she wants to find a certain, desktop-related option, say adding widgets, opening the desktop settings dialog, the activity switcher, etc.. For this, Plasma 4.0 introduced the toolbox, a small icon that when clicked opens a small dialog with actions related to the desktop. To many users, this is an important lifeline when they’re looking for a specific option.

In Plasma 4.x, there was a Plasmoid, provided by a third party, that used a pretty gross hack to remove the toolbox (which was depicted as the old Plasma logo, resembling a cashew a bit). We did not support this officially, but if people are deliberately risking to break their desktop, who are we to complain. They get to keep both pieces.

During the migration to QML (which begun during Plasma 4.x times), one of the parts I had been porting to QtQuick was this toolbox. Like so many other components in Plasma, this is actually a small plugin. That means it’s easy to replace the toolbox with something else. This feature has not really been documented as its more or less an internal thing, and we didn’t want to rob users of this important lifeline.

Some users want to reduce clutter on their desktop as much as possible, however. Since the options offered in the toolbox are also accessible elsewhere (if you know to find them). Replacing the toolbox is actually pretty easy. You can put a unicorn dancing on a rainbow around your desktop there, but you can also replace it with just an empty object, which means that you’re effectively hiding the toolbox.

For users who would rather like their toolbox to be gone, I’ve prepared a small package that overrides the installed toolbox with an empty one. Hiding the toolbox is as easy as installing this minimal package, which means the toolbox doesn’t get shown, or even get loaded.

I would not recommend doing this, especially not as default, but at the same time, I don’t want to limit what people do with their Plasma do what we as developers exactly envision, so there you go.

Download this file, then install it as follows:


plasmapkg2 -t package -i emptytoolbox.plasmoid

Now restart the Plasma Shell (either by stopping the plasmashell process, or by logging out and in again), and your toolbox should be gone.

If you want it back, run

plasmapkg2 -t package -r org.kde.desktoptoolbox

Then restart Plasma and it’s back again.

Even more than just removing the toolbox, I’d like to invite and encourage everybody to come up with nice, crazy and beautiful ideas how to display and interact with the toolbox. The toolbox being a QtQuick Plasmoid package, it’s easy to change and to share with others.
