The environment in these examples has eight Virtual Desktops.

Display Application on all Desktops and One of Its Children Types Differently

Except for conversation windows, display Kopete and its children windows (e.g. Configuration) on all desktops and skip the systray and pager (the Virtual Desktop view in systray). For conversation windows, treat them as the parent window except show them in systray.

In order to implement the above, two rules need to be created:

1. A rule for Kopete Chat and
2. A rule for Kopete

The Kopete Chat rule's matching-criteria is more restrictive than the Kopete rule as it needs to match a specific Window Role: the chat window. Due to rule evaluation processing, the Kopete Chat rule must precede the Kopete rule in the KWin Rule list for Kopete.

Kopete Chat Rule

Assuming a Kopete Chat window is open:

1. Use Detect Window Properties and select the Kopete Chat window. Check the Window role box to restrict the criteria to chat windows:

   

2. Clicking OK in the previous window back-fills the results in the Window Matching tab. Enter a meaningful Description:

   

3. Enable the following attributes:

   

   

4. Click through to complete entry of the rule.

Note

The Skip taskbar attribute is set to No to display the window in the taskbar: no skip taskbar or do not skip taskbar.

Kopete Rule

Assuming Kopete is open:

1. Use Detect Window Properties and select the Kopete window. Check the Secondary class name box to include all of Kopetes children windows:

   

2. Clicking OK in the previous window back-fills the results in the Window Matching tab. Enter a meaningful Description:

   

3. Enable the following attributes:

   

   

4. Click through to complete entry of the rule.
