KWin Rules

Overview

KWin allows the end-user to define rules to alter the behavior of applications.

Tip

Plasmoids, Workspaces can also be affected.

For example, when an application is started, it can be forced to always run on Virtual Desktop #2. Or a defect in an application can be worked-around by using a rule to, say, always force the window on top of all others.

This page will define the different settings and the attributes. For the impatient folks, working examples will be listed. Whenever possible, screen shots will be used to show example settings.

KWin Rule Editor Anatomy

The editor is comprised of four tabs:

1. Window matching
2. Size & Position
3. Arrangement & Access
4. Appearance & Fixes

As the name implies, Window matching is used to specify criteria to match one or more windows. The other three tabs are used to alter the window's characteristics.
