Hinweise
BehaviorService Beim Erstellen wird ein transparentes Fenster über dem Designerrahmen hinzugefügt. Anschließend BehaviorService kann dieses Fenster zum Rendern von Benutzeroberflächenelementen, aufgerufenen Glyph Objekten sowie zum Erfassen aller Mausnachrichten verwendet werden. Auf diese Weise kann das BehaviorService Designerverhalten gesteuert werden.
Die BehaviorService Klasse unterstützt einen Verhaltensstapel, auf den Behavior Objekte verschoben werden können. Wenn eine Nachricht durch das transparente Fenster abgefangen wird, kann die BehaviorService Nachricht Behavior am oberen Rand des Stapels gesendet werden. Dies ermöglicht unterschiedliche Benutzeroberflächenmodi je nach aktuell pushen Behavior. Dies BehaviorService wird verwendet, um alle Glyph Objekte zu rendern, z. B. Auswahlrahmen, Größenziehpunkte und Smarttags. Außerdem BehaviorService werden viele Entwurfszeitverhalten gesteuert, z. B. Mithilfe von Snaplines, Ziehen und Auswählen.
Weitere Informationen finden Sie unter "Behavior Service Overview".
Eigenschaften
| Adorners |
Ruft das BehaviorServiceAdornerCollection ab. |
| AdornerWindowGraphics |
Ruft die Graphics für das Gestaltungsfenster ab. |
| CurrentBehavior |
Ruft das Behavior an der obersten Position des Verhaltensstapels ab, ohne es zu entfernen. |
Methoden
| AdornerWindowPointToScreen(Point) |
Wandelt einen Point im Gestaltungsfenster in Bildschirmkoordinaten um. |
| AdornerWindowToScreen() |
Ruft die Position des Gestaltungsfensters in Bildschirmkoordinaten ab. |
| ControlRectInAdornerWindow(Control) | |
| ControlToAdornerWindow(Control) |
Gibt die Position eines Control als Gestaltungsfensterkoordinaten zurück. |
| Dispose() |
Gibt alle vom BehaviorService verwendeten Ressourcen frei. |
| Equals(Object) |
Bestimmt, ob das angegebene Objekt gleich dem aktuellen Objekt ist. (Geerbt von Object) |
| GetHashCode() |
Fungiert als Standardhashfunktion. (Geerbt von Object) |
| GetNextBehavior(Behavior) |
Gibt das Behavior unmittelbar nach dem angegebenen Behavior im Verhaltensstapel zurück. |
| GetType() |
Ruft den Type der aktuellen Instanz ab. (Geerbt von Object) |
| Invalidate() |
Führt dazu, dass das Gestaltungsfenster des BehaviorService ungültig wird. |
| Invalidate(Rectangle) |
Führt dazu, dass der angegebene Bereich des BehaviorService innerhalb des Gestaltungsfensters ungültig wird. |
| Invalidate(Region) |
Führt dazu, dass der angegebene Bereich des BehaviorService innerhalb des Gestaltungsfensters ungültig wird. |
| MapAdornerWindowPoint(IntPtr, Point) |
Konvertiert einen Punkt im Koordinatensystem eines Handles in die Gestaltungsfensterkoordinaten. |
| MemberwiseClone() |
Erstellt eine flache Kopie des aktuellen Object. (Geerbt von Object) |
| PopBehavior(Behavior) |
Entfernt das Behavior am Anfang des Stapels und gibt es zurück. |
| PushBehavior(Behavior) |
Legt ein Behavior auf dem Verhaltensstapel ab. |
| PushCaptureBehavior(Behavior) |
Legt ein Behavior auf dem Verhaltensstapel ab und weist dem Verhalten die Mausereignisse zu. |
| ScreenToAdornerWindow(Point) |
Wandelt einen Punkt in Bildschirmkoordinaten in die Gestaltungsfensterkoordinaten des BehaviorService um. |
| SyncSelection() |
Synchronisiert alle Auswahlsymbole. |
| ToString() |
Gibt eine Zeichenfolge zurück, die das aktuelle Objekt darstellt. (Geerbt von Object) |
Ereignisse
| BeginDrag |
Tritt ein, wenn der BehaviorService einen Drag & Drop-Vorgang startet. |
| EndDrag |
Tritt ein, wenn der BehaviorService einen Ziehvorgang abschließt. |
| Synchronize |
Tritt ein, wenn die aktuelle Auswahl aktualisiert werden soll. |
