Hiedie opsie spesifiseer hoeveel KWin probeer om te keer dat nuwe vensters die fokus steel. Hierdie opsie werk nie vir 'Fokus onder Muis' en 'Fokus streng onder Muis' beleid nie. Geen: Voorkoming word af gesit en nuwe vensters word altyd aktief Laag: Voorkoming is aktief. Vir vensters wat nie die onderliggende meganisme ondersteun nie sal dit aktief gemaak word Normaal: Voorkoming is aktief. Hoog: Nuwe vensters sal geaktiveer word as dit aan die huidige aktiewe program behoort. Dit sal nie geaktiveer word as 'n ander venster aktief is nie. Hierdie opsie maak meeste sin saam met' n muis fokus beleid. Ekstreem: Alle vensters moet spesifiek deur die gebruiker geaktiveer word Vensters wat verhoed word om die fokus te steel sal aandui dat hulle aandag benodig. Gewoonlik beteken dit dat hulle taakbalk inskrywing verlig is. Dit kan in die Inkennisstelling beheer module verander word.
This option specifies how much KWin will try to prevent unwanted focus stealing caused by unexpected activation of new windows. (Note: This feature does not work with the Focus Under Mouse or Focus Strictly Under Mouse focus policies.) None: Prevention is turned off and new windows always become activated. Low: Prevention is enabled; when some window does not have support for the underlying mechanism and KWin cannot reliably decide whether to activate the window or not, it will be activated. This setting may have both worse and better results than the medium level, depending on the applications. Medium: Prevention is enabled. High: New windows get activated only if no window is currently active or if they belong to the currently active application. This setting is probably not really usable when not using mouse focus policy. Extreme: All windows must be explicitly activated by the user. Windows that are prevented from stealing focus are marked as demanding attention, which by default means their taskbar entry will be highlighted. This can be changed in the Notifications control module.
