+# Wrapper‑Architektur – Übersicht
+Die Wrapper‑Architektur von sn_basis bildet das Fundament für eine robuste, testbare und zukunftssichere QGIS‑Plugin‑Entwicklung.
+Sie kapselt sämtliche QGIS‑ und Qt‑Abhängigkeiten hinter klar definierten Schnittstellen und ermöglicht dadurch:
+
+Mock‑fähige Unit‑Tests ohne QGIS
+
+PyQt5/6‑Kompatibilität ohne Code‑Änderungen
+
+saubere Trennung von UI, Logik und Infrastruktur
+
+stabile APIs, die unabhängig von QGIS‑Versionen bleiben
+
+klare Erweiterbarkeit für zukünftige Module und Plugins
+
+Die Wrapper‑Schicht ist das zentrale Bindeglied zwischen der Plugin‑Logik und der QGIS‑/Qt‑Umgebung.
+
+## Ziele der Wrapper‑Architektur
+🎯 1. Entkopplung von QGIS und Qt
+Alle direkten Importe wie from qgis.core import ... oder from qgis.PyQt.QtWidgets import ... verschwinden aus der Plugin‑Logik.
+Stattdessen werden sie über Wrapper‑Module abstrahiert.
+
+🎯 2. Testbarkeit ohne QGIS
+Im Mock‑Modus liefern die Wrapper:
+
+Dummy‑Objekte
+
+simulierte Rückgabewerte
+
+speicherbare Zustände (z. B. Variablen, Layer, Nachrichten)
+
+Damit laufen Tests in jeder CI‑Umgebung.
+
+🎯 3. Einheitliche API für alle Plugins
+Plugins greifen nicht mehr direkt auf QGIS zu, sondern nutzen:
+
+Code
+sn_basis.functions.qgiscore_wrapper
+sn_basis.functions.qgisui_wrapper
+sn_basis.functions.qt_wrapper
+sn_basis.functions.variable_wrapper
+sn_basis.functions.message_wrapper
+sn_basis.functions.dialog_wrapper
+🎯 4. Zukunftssicherheit
+Ändert sich die QGIS‑ oder Qt‑API, wird nur der Wrapper angepasst, nicht jedes Plugin.
+
+## Architekturüberblick
+Die Wrapper‑Schicht besteht aus mehreren Modulen, die jeweils einen klar abgegrenzten Verantwortungsbereich haben.
+
+### 1. qt_wrapper – Qt‑Abstraktion
+Kapselt alle Qt‑Widgets, Dialoge und Konstanten:
+
+QWidget, QDialog, QMessageBox, QToolBar, QMenu, …
+
+Layouts, Buttons, Labels, LineEdits
+
+Qt‑Konstanten wie YES, NO, Dock‑Areas
+
+Mock‑Modus:  
+Stellt Dummy‑Widgets bereit, die keine UI öffnen.
+
+### 2. qgiscore_wrapper – QGIS‑Core‑Abstraktion
+Abstraktion für:
+
+QgsProject
+
+Layer‑Zugriff
+
+Projekt‑Metadaten
+
+Pfade, CRS, Feature‑Zugriff
+
+Mock‑Modus:  
+Simuliert ein Projekt und Layer‑Container.
+
+### 3. qgisui_wrapper – QGIS‑UI‑Abstraktion
+Kapselt UI‑bezogene QGIS‑Funktionen:
+
+Zugriff auf iface
+
+Dock‑Management
+
+Menü‑ und Toolbar‑Integration
+
+Hauptfenster‑Zugriff
+
+Mock‑Modus:  
+Stellt ein Dummy‑Interface bereit.
+
+### 4. variable_wrapper – QGIS‑Variablen
+Abstraktion für:
+
+Projektvariablen (projectScope)
+
+globale Variablen (globalScope)
+
+Mock‑Speicher für Tests
+
+Vorteile:
+
+keine QGIS‑Abhängigkeit in der Logik
+
+testbare Variablenverwaltung
+
+einheitliches API
+
+### 5. message_wrapper – Meldungen & Logging
+Einheitliche Schnittstelle für:
+
+Fehlermeldungen
+
+Warnungen
+
+Info‑Meldungen
+
+Logging
+
+Mock‑Modus:
+Speichert Nachrichten statt sie an QGIS zu senden.
+
+### 6. dialog_wrapper – Benutzer‑Dialoge
+Abstraktion für:
+
+Ja/Nein‑Dialoge
+
+spätere Erweiterungen (Eingabedialoge, Dateidialoge, etc.)
+
+Mock‑Modus:
+Gibt Default‑Werte zurück, öffnet keine UI.
+
+### 7. DockManager & Navigation
+Diese Module nutzen die Wrapper‑Schicht, um:
+
+DockWidgets sicher zu verwalten
+
+Toolbars und Menüs zu erzeugen
+
+Reload‑sichere UI‑Strukturen aufzubauen
+
+Sie sind keine Wrapper, sondern Wrapper‑Konsumenten.
+
+## Designprinzipien
+🧱 1. Single Source of Truth
+Jede QGIS‑ oder Qt‑Funktionalität wird nur an einer Stelle implementiert.
+
+🔄 2. Austauschbarkeit
+Mock‑Modus und Echtmodus sind vollständig austauschbar.
+
+🧪 3. Testbarkeit
+Jede Funktion kann ohne QGIS getestet werden.
+
+🧼 4. Saubere Trennung
+UI → qt_wrapper
+
+QGIS‑Core → qgiscore_wrapper
+
+QGIS‑UI → qgisui_wrapper
+
+Logik → settings_logic, layer_logic, prüfmanager, …
+
+🔌 5. Erweiterbarkeit
+Neue Wrapper können jederzeit ergänzt werden, ohne bestehende Plugins zu brechen.
+
+## Vorteile für Entwickler
+Keine QGIS‑Abhängigkeiten in der Logik
+
+IDE‑freundlich (Pylance, Autocomplete, Typing)
+
+CI‑fähig (Tests ohne QGIS)
+
+saubere Architektur
+
+leichte Wartbarkeit
+
+klare Dokumentation
+
+## Fazit
+Die Wrapper‑Architektur ist das Herzstück von sn_basis.
+Sie ermöglicht eine moderne, modulare und testbare QGIS‑Plugin‑Entwicklung, die unabhängig von QGIS‑Versionen, Qt‑Versionen und Entwicklungsumgebungen funktioniert.
+
+Sie bildet die Grundlage für:
+
+stabile APIs
+
+saubere UI‑Abstraktion
+
+automatisierte Tests
+
+nachhaltige Weiterentwicklung
