Overview
KWin allows the end-user to define rules to alter the behavior of an application's window attributes.
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 document provides working examples along with detail information about the KWin Rule Editor functionality.
Examples
A collection of examples is provided to convey the power of KWin window rules.
KWin Rule Editor
Invoking the Editor
There are several ways one can invoke the ules editor. Below are a couple:
- Right-click on the title-bar of any window, choose and in the Configure window, select or
Anatomy
The editor is composed of four tabs:
As the name implies,
is used to specify criteria to match one or more windows. The other three tabs are used to alter the attributes of the matching windows.
Rule Evaluation
When an application starts (or the rules are modified), KWin evaluates the rules from the top of the list, looking for the first matching rule. If a rule matches, the attributes set in the rule are applied to the window and the window is displayed.
Window Matching
Each window rule has user specified window matching criteria. KWin uses the criteria to determine whether the rule is applicable for an application.
Window Attributes
Along with Window Matching criteria, each window rule has a set of window attributes. The attributes override the corresponding application's settings and are applied before the window is displayed by KWin.
