Ein leerer Desktop von KDE 4.5

Der verlässliche und flexible Fenster-Manager des KDE Plasma Desktops, jetzt mit Effekten!

Feature-Übersicht

• Stabil und verlässlich
• Compositing, 3D-Effekte
• Einfache Konfigurierung
• Verbesserte Leistungsfähigkeit

KWin (sprich "kwin") ist der Fenstermanager für den KDE Plasma Desktop. Es gibt Ihnen die vollständige Kontrolle über Ihre Fenster, so dass Sie nicht im Weg sind, aber Ihnen bei Ihren Aufgaben helfen. Er malt die Fensterdekoration, die Bar am Anfang von jedem Fenster mit (konfigurierbar) Schaltflächen wie zu schließen, zu maximieren und zu minimieren. Es verwaltet auch dass platzieren von Fenstern und das Umschalten zwischen ihnen.

KWin unterstützt 'Compositing', der Umgang mit Ihren Fenstern mittels 3D-Effekten. Dies kann dazu führen, das dass Fenstermanagement glatter, leichter, effizienter und natürlicher wird. Die Hardware-Anforderungen sind sehr bescheiden, und so ziemlich jedes halbwegs moderne System seit 2002 unterstützt wird. Es gibt noch einige Probleme mit bestimmter Hardware, weitere Infos darüber finden Sie auf techbase

Nützliche Funktionen

Click with your right mouse button on a window decoration or use System Settings to access the new and easier configuration of KWin. Here you can enable effects to more efficiently manage your windows. You can for example use the Present Windows as the effect for window switching. Instead of showing you icons or very small previews of your applications, it arranges them in a grid so you can quickly choose the right one. Just use the Alt-Tab keysequence and keep the Alt key pressed. You can now use tab to switch through the windows or just activate the right one using the mouse. Hitting Alt-Tab keys quickly will show you the next window in the queue, just like it used to.

If your X server already supports compositing, switching it on is as easy as opening System Settings, opening the Worskpace Appearance and Behaviour module, choosing Desktop Effects and enabling the checkbox Enable desktop effects at startup. More advanced compositing settings (such as Use VSync, Scale method, Compositing type) are available through the Advanced dialog. Customising the behaviour of the KWin effects means opening the All effects tab, and choosing the plugins you want to use. Please note that only a subset of the plugins works with XRender-based compositing. For the full experience, you need to use OpenGL mode.

Employing motion physics, KWin provides your windows with a more natural feel. New desktop effects like the Cube desktop switcher and Magic Lamp minimize animation have been added. Improvements in the existing effects make window management smoother than ever. KWin has seen many performance improvements to enable these effects even on low-end hardware. Elaborate checks have been build in to ensure users with low-end hardware are not presented with an unusable setup. KWin detects the capabilities of the hardware and if needed gracefully scales its effects down. You can take control and disable these checks or change settings like the global animation speed to fine-tune your experience. When your computer is under heavy load, KWin will automatically disable the compositing temporarily to keep things running smoothly. It will notify you if it does so, and you can re-enable compositing by pressing Shift+Alt+F12. Finally, support for multiple screen handling has been improved in KWin using the new Kephal library. You can move maximized windows between Xinerama screens and the addition of external screens is handled correctly.

Tutorials

Eine Anwendung immer mit einer bestimmten Größe und/oder Position starten

Size and Position

Sometimes the screen position of an application is vital to your comfort, so use the flexibility of KWin to make sure it's always where you want it.

Position the window where you want it to open, then right-click on the title-bar, choosing Advanced -> Special Window Settings. This will open a settings window, with appropriate entries already made. All you need to do now is select the Size & Position tab and check Position and Size. OK - you are finished!

Script the window manager from the command line

Use the WMIface utility.

Die Position der Titelleisten-Knöpfe verändern

Configure Buttons

Take a look at System Settings -> Application Style -> Window Decorations -> Buttons tab. The options open to you may depend on your distribution or theme, and it's clear that there is more to come.

To simply move things around you work with the specimen titlebar - that is the dark blue bar with a large KDE on it. Drag icons there and you will see them move in the preview window at the bottom of the screen.

You may find that you have other icons available to you. A circle indicates that the button will set that window on all desktops. Another icon that you may find useful is Shade - a toggle between rolled up (titlebar only visible) and normal view. These icons are added by dragging from the text description window onto the speciman title bar - just position them as you want to use them.

Falls Sie einen klassischen KDE3-ähnlichen Desktop bevorzugen

Change to traditional desktop

Right-click on your desktop - select Desktop Settings (or Appearance Settings, in some distros). Change the Layout: from Desktop to Folder View. The whole desktop is now a folderview, and another right-click on the desktop will allow you to select FolderView Settings. Set the folderview to the directory you want to use as your desktop.

Open applications directly into a different desktop

Verwenden Sie einen Befehl, wie:

kstart5 --desktop 4 kate

Verwendung auf kleinen Bildschirmen (z. B. Netbooks)

Die Fensterdekoration verkleinern

Breeze-, Plastik- und Oxygen-Fensterdekoration

System Settings -> Application Style -> Window Decorations tab. Two good options there:

Configure Breeze Style

• Using the default style (Breeze), select Configure Decoration and set Button size to Tiny or Small.
• Using an other style, with smaller windows decorations.

Both routes will give you slim and functional window titles and borders.

Change the base fonts

On many netbooks the screen is very clear, so that reading fonts much smaller than you expect is feasible. On Acer Aspire One I find that 8 point is a good base settings.

Schriftart in Firefox verkleinern

Experimente mit about:config bringen nicht zufrieden stellende Ergebnisse. Versuchen Sie stattdessen folgendes. Laden und Installation Sie gtk-chtheme von diese Webseite. Mit diesem Tool können Sie entweder eine bestimmte Schriftgröße, oder noch besser, verwenden Sie die KDE-Einstellungen. Dies wird mit Firefox sowie alle GNOME-Anwendungen, die Sie verwenden, funktionieren.

Troubleshoot Graphics Problems

Curing graphics problems depends on knowing the correct drivers for your graphics card. Learn more about this on the Desktop Effects Performance page.

Defining Window Rules

There is a tutorial on defining your own rules for the behaviour of specific windows on the KWin Rules pages.
