WHAT IS THAT ?
Py-Cashew is a KDE4 plasmoid that hides the desktop toolbox, also known as the cashew. Some find the cashew pretty but others who don't have no way to remove it. The KDE developers made it clear that they won't add an option to hide it (see this KDE faq entry), so this plasmoid offers a way out.
Py-cashew is very much like "I HATE the cashew" that seems to have disappeared from KDE-look.org. It is written in python so you won't have to compile it to use it. It simply hides the cashew, if you need more configurability, take a look at Stealth Cashew.
KDE versions 4.6 to 4.11 are supported. Py-cashew may or may not work with previous versions.
Py-Cashew is a stupid name, another reason to try it !
Py-cashew is available on kde-look
HOW TO INSTALL IT ?
Plasmoids installation is described in the KDE userbase wiki. The easiest way to install Py-cashew is to get it from kde-look. Simply drop Py-Cashew in your desktop, no new widget should show up and the cashew should be gone. If something goes wrong, you will get a small widget with an error message, you can simply remove it. This will happen if the cashew is already hidden.
From the source repository, you can generate the plasmoid file by typing make and install it for the current user with make install.
HOW TO REMOVE IT ?
With previous versions of KDE, there was an easy way to remove hidden plasmoids by clicking on the minus sign in the "add plasmoid" window. With the current version you can either create a new activity but you will lose all your current settings.
Or you can edit the file
~/.kde4/share/config/plasma-desktop-appletsrc and remove the section about py-cashew like the example here :
[Containments][Applets] geometry=1003,574,200,200 immutability=1 plugin=py-cashew zvalue=0
Then you need to logout and log back in for the change to be effective: The cashew should be back. Make sure you have a backup of the file in case you mess things up.
Another method is to uninstall Py-Cashew completely, this can be done by running the command:
plasmapkg -r py-cashew
or if you have the sources, by typing:
And logging out and back. You should get an empty plasmoid on your desktop, just remove it.
