Overview
KWin allows the end-user to define rules to alter the behavior of applications.
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.
Rule Evaluation
KWin evaluates the rules when an application starts and after editing rules. Any matching rule's attribute(s) override the application's corresponding attribute(s).

Rule Precedence
In the event two rules match a window and affect the same attribute, the first rule in the list takes precedence.
