KWin (pronounced "kwin" in one word) is the window manager for the KDE Plasma Desktop. It gives you complete control over your windows, making sure they're not in the way but aid you in your task. It paints the window decoration, the bar on top of every window with (configurable) buttons like close, maximize and minimize. It also handles placing of windows and switching between them.

KWin поддерживает композитность, что означает использование трёхмерных эффектов при отрисовке окон. Это может сделать управление окнами более гладким, лёгким и более эффективным и естественным. Его аппаратные требования очень скромные, и почти каждая разумно современная система с 2002 года поддерживает его. Могут быть небольшие проблемы с некоторой аппаратурой, более подробно на эту тему можно узнать на странице KWin в TechBase.

Удобные возможности

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

You want an application to launch in a specific size and position every time

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.

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.

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.

Запуск приложения сразу на другом рабочем столе

Используйте команду наподобие этой:

kstart5 --desktop 4 kate

Breeze, Plastik, and Oxygen Styles

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.

Измените базовые шрифты

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.

Сделайте чтобы Firefox использовал шрифты меньшего размера

Experimentation with about:config did not bring satisfactory results. Do this instead. Download and install gtk-chtheme from this website. Using that tool you can either set a specific font size, or better still, tell it to use your KDE desktop settings. This will work with Firefox as well as any gtk applications that you use.

Gallery

The Gallery holds many screenshots of past and present desktops and effects.

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.
