Widgets and Plasmoids

Here are some of our favourites:

System Widgets

Device Notifier

The Device Notifier is used for handling pluggable devices such as USB pendrives (also called flash drives or thumb drives), digital cameras, external USB hard drives etc. It also comes into play when a medium such as a CD or DVD is loaded into an optical drive.

When the you plug in an external device, or load a new medium into a drive, KDE pops up the Notifier window (you can also open it explicitly by clicking on its Panel icon.) It stays open while the cursor is over it, otherwise it hides itself after a few seconds.

The Notifier window shows a list of all the devices it currently knows about. Moving the mouse cursor over a device will highlight how many possible actions are associated with that device. If the device is mounted, there will also be a small icon to the right of it. Clicking on this causes the device to be unmounted and/or the medium to be ejected. Note that unmounting/ejecting might fail if the device still has open files on it, e.g. if a large file copy hasn't finished. In most cases you can just wait a while and try again.

Clicking anywhere in the shaded box around the device name (but not on the eject/unmount icon if present) pops up a dialogue box with a list of possible actions that make sense for that device. Simply select one and click on OK or hit the Enter key. Double-clicking also works. The Cancel button dismisses the pop-up without taking any action.

Weather Widgets

Weather widgets are especially popular if you live in a country with very changeable weather, such as the U.K.

LCD Weather Plasmoid

The LCD weather plasmoid gets its information from one of three sources, the BBC weather from the UK Met. Office, NOAA's National Weather Service, or Environment Canada. If it can locate a weather station near you it will give you a range of details about the current weather.

It can also be installed to the Task-bar, in which case you get an icon-size display which simply shows the current outside temperature.

YAWP (Yet Another Weather Plasmoid)

YAWP uses Accuweather as its source, and can be configured to show one to five days' forecast. The update period is configurable.  See footnote

In the 5-day forecast mode, today's information is at the top of the screen,with the next four days shown below. Click on the and you will see a more detailed forecast.

Use the small white arrows to navigate through the days visible. When you want to return to the main display, click on the again.

Clicking on brings up a satelite weather picture.

CWP (Configurable Weather Plasmoid)

CWP's strength is in the large number of configuration options. It can draw data from sources scattered across the globe, and has far more display options than either the LCD plasmoid or Yawp. It can also display a summary for up to 7 days ahead.

You can, however, only see the details for the current day. This is accessed by clicking on the current temperature, and closed the same way.

Productivity Widgets

Pastebin Plasmoid

This useful tool can be made quite small, to save desktop space, but is invaluable when you need to show a configuration file or screenshot which is too big to be accepted by email. It's also perfect for use with an IRC query.

To use it, simply drag the required file onto the plasmoid. The plasmoid will then show 'Drop!'. When you drop your file it will give the URL for accessing it from the server, and can copy it to the clipboard for you. It uses both Pastebin and Imagebin servers.

PowerDevil

A battery icon sits in your panel. According to your choice of configuration, it can display the remaining amount of charge, or display it when you hover over it. Click on the battery and you get the summary display, while clicking on the More button takes you to a full configuration screen (click to view enlargement of images).

The Config screen

A further screen allows you to define and manage a number of profiles, and the final screen gives a summary of your computer or laptop's power-saving capabilities.

Finally, PowerDevil configurations can be set from krunner, as described in detail here
