The tab is used to specify the criteria KWin uses to evaluate whether the rule is applicable for a given window.
Zero (match any window) or more of the following may be specified:
- - match this window.
- and - ... and all its children windows.
- - restrict the match to the function of the window (e.g. a main window, a chat window, etc.)
- - restrict the match to the type of window: Normal Window, Dialog Window, etc.
- - restrict the match to the title of the window.
- - restrict the match to the host name associated with the window.

For each field, the following operators can be applied against the field value:
- - ignore the field.
- - case insensitive.
- - case insensitive.
- - Qt's regular expressions are implemented. For additional information, web search qt regex nokia.
