Plasma/pl

W skrócie

Plasma to przestrzeń robocza KDE. Obecnie jest to technologia dostosowana do różnych typów urządzeń. Aktualnie mamy trzy rodzaje Plasmy: środowisko graficzne Plasma Desktop, na którym skupiona jest większość tych stron, środowisko Plasma Netbook i Plasma Active - nowe, świetne środowisko dla tabletów i smartfonów.

Typowy pulpit Plasmy wygląda tak:

Cztery kluczowe komponenty domyślnego pulpitu Plasmy to:

• Panel, znany także jako "pasek zadań", dostarcza miejsce na aktywatory programów, listę otwartych okien (programów), zegar i tackę systemową;
• Pulpit, obszar w którym rozmieszczone są ikony i widgety;
• Widok katalogu, widget, który wyświetla zawartość katologu na twoim komputerze, dając ci szybki dostęp do podstawowych zadań zarządzania plikami;
• Skrzynka narzędziowa umieszczona w górnym prawym rogu ekranu, a także na końcu panela. Używana w celu szybkiego i niezawodnego dostępu do konfiguracji i innych opcji.

Wszystkie domyślne elementy są w pełni konfigurowalne i dostarczają szeroką gamę narzędzi i treści.

Plasma Desktop FAQ

"Najczęściej Zadawane Pytania" dla aktualnej wersji Plasma Desktop można znaleźć na tej stronie. Znajdują się tam odpowiedzi do najczęściej zadawanych pytań oraz linki do najczęściej zadawanych pytań dla starszych wersji.

Odkrywanie Plasmy

Możesz używać Plasmy tak jak pulpitu każdego innego systemu operacyjnego, poprzez dostęp do aktywatorów programów, przeglądanie aktualnie uruchomione programów na pasku zadań oraz dostęp do ikon w tacce systemowej i tym podobne.

Ważną częścią Plasmy są "widgety". Widgety to samodzielne elementy pulpitu, które obejmują (choć nie są ograniczone tylko do nich) menu programów, ikony, tackę systemową, zegar itp. Widżety mogą występować na samym pulpicie, albo być dodawane do panelu, do wygaszacza ekranu, tablicę Plasmy. Widgety posiadają wiele różnych zadań oprócz zwykłej pomocy dla pulpitu w tym m.in. microblogging (Twitter, identi.ca), przeliczanie jednostek, stacja pogodowa, współdzielenie plików i wiele innych. Panele i pulpity są także specjalnymi rodzajami widgetów, które mogą zawierać inne widgety.

How does that relate with desktop usage? Plasma has some new features with respect to traditional desktop usage. We have already mentioned the Plasma toolboxes: those are the way to start interacting and customizing your Plasma Desktop. By clicking on them, a menu will pop up on the screen with a variety of choices: from there you can add widgets to your panel or desktop, resize, add or remove panels, change the wallpaper and other operations.

Folder Views

As you may notice in the screenshot above, there are no icons placed directly on the desktop. Instead, they are placed inside a container called a "Folder View". By default, the Folder View shows the Desktop folder and allows you to drag files to it, open them, cut, copy, paste, rename files and also create new folders/files.

You can have more than one Folder View on the desktop, and they can also be placed in panels. You can set Folder View to show any folder, local or remote, you have access to. Each Folder View can be moved and resized independently to your preference.

Folder View can also be set as the default full-screen desktop background for a more traditional "icons scattered on the desktop" layout.

Panels

Panels allow you to place widgets around the edges of the screen. These collections of widgets can be configured in various ways, including making them automatically hide when not in use or aligned to certain areas of the screen.

By default, there is one panel at the bottom of the screen, but you can add more panels, move and otherwise configure the default panel and remove panels you no longer want. The widgets in all of the panels may also be adjusted to your liking.

For more information on configuring panels in Plasma Desktop and what they are capable of doing for you, visit the Plasma Panels page.

Widgets

Plasma Widget Explorer

Plasma supports widgets written specifically for Plasma (also known as Plasmoids) as well as widgets from other sources such as Google Gadgets, Superkaramba and some Dashboard Widgets from Mac OSX. Additional widgets can easily be found and installed through Get Hot New Stuff.

To see the widgets that are installed on your system and ready to use open the Plasma Widget Explorer by either

• opening the Desktop Toolbox in the upper right corner of the screen and selecting Add Widgets,
• opening the Panel Toolbox furthest to the right in the Panel and selecting Add Widgets, or
• right clicking on the Desktop and choosing Add Widgets from the context menu.

To place a widget on the Desktop simply drag it from the Widget Explorer to the Desktop. To place a widget in the panel first open the Panel Toolbox and from there open the Widget Explorer (click Add Widgets), locate the widget you wish to add and drag it to the desired position in the Panel.

Note

You can not add widgets if they are locked. Open the Desktop Toolbox or the Panel Toolbox or right click on the Desktop - if you see an item labeled Unlock Widgets then select that, and then proceed to add widgets to your Desktop or your Panel.

When you are done adding widgets you might want to lock widgets again: Open a Toolbox or the Desktop context menu and click Lock Widgets.

Widgets that are docked into a panel usually have an Options menu, while those on the desktop have the configuration options within the 'handle', the shaded area which pops up when hovering over the widget. Clicking and holding the mouse on the blank part of the handle will allow you to drag the widget to the desired position.

You have four tools on this handle. The top one is the re-sizer. Click and drag on the tool to resize the widget.

The second tool is a rotate tool. Again, click and hold the tool, while rotating to the desired angle.

The third is the wrench or spanner which allows you to configure that particular widget's settings.

Finally, the fourth tool is the "expanded view" tool and is available only on widgets that support this feature, such as the Picture Frame or Web viewers. When clicked, the Picture Frame widget will, for example, open the currently viewed in an image viewer while the Web Slice widget will open the web page in a full web browser window.

A list of Plasma widgets with their own page can be found here, and some of our favourite widgets are discussed on the Plasma Widgets page

Activities

The icons shown in the screenshot have small buttons in the top right and bottom right. The small pause button in the top right prevents the activity from being included when switching through Activities using Super + Tab. It also opens up an "x" to delete the activity. To change the names of the activities, look for the small wrench in the bottom right of the icon.

Plasma Activity Explorer

Use Cases

A user likes web comics so they add their favorite web comics via the comics widget. The user now has a full desktop activity dedicated to their favorite web comics. Now the user is happy with the web comics, but the user now has to go to work, so the user creates an activity with the folder view widgets set to the folders of the projects the user is currently working on. After work the user goes home and works on a side project of writing romance novels. The user always gains inspiration by looking at pictures of the user's significant other. The user now creates a new Activity but now puts pictures frame widgets with pictures of the user's significant other. The user also has a folder view of the romance novel project folder. Now no matter what the user is doing the user has a custom tailored activity to match it.

Go to this blog to read a few tips on using activities. Chanis blog has a number of examples as well as screencasts about activities.

Widget Layouts and Virtual Desktops

Virtual desktops, the ability to have a separate sets of windows on separate desktops, can tie in with Activities. You can have a different activity on each virtual desktop. In Plasma Desktop 4.4, this can be configured by entering System Settings and navigating to Desktop -> Multiple Desktops, and checking Different Activity for Each Desktop.

In Plasma Desktop 4.3, You configure this by zooming out and choosing configure Plasma. Then select use a different activity on each desktop and zoom in again.
