StringFormat.GetTabStops(Single) Methode

Definition

Namespace:

System.Drawing

Assembly:

System.Drawing.Common.dll

Paket:

System.Drawing.Common v8.0.0

Quelle:

StringFormat.cs

Ruft die Tabstopps für dieses StringFormat-Objekt ab.

public:
 cli::array <float> ^ GetTabStops([Runtime::InteropServices::Out] float % firstTabOffset);

public float[] GetTabStops (out float firstTabOffset);

member this.GetTabStops : single -> single[]

Public Function GetTabStops (ByRef firstTabOffset As Single) As Single()

Parameter

firstTabOffset

Single

Die Anzahl von Leerzeichen zwischen dem Anfang einer Textzeile und dem ersten Tabstopp.

Gibt zurück

Single[]

Ein Array von Abständen (als Anzahl der Leerzeichen) zwischen Tabstopps.

Beispiele

Das folgende Beispiel ist für die Verwendung mit Windows Forms konzipiert und erfordert PaintEventArgse, was ein Parameter des Paint Ereignishandlers ist. Der Code führt die folgenden Aktionen aus:

• Legt die Tabstopps von fest StringFormat.

• Zeichnet die Zeichenfolge und das Layoutrechteck. Beachten Sie, dass die Zeichenfolge Registerkarten enthält. Die Registerkarteneinstellungen des StringFormat geben die Offsets des Texts im Registerkartenformat an.

• Ruft die Registerkarte ab und verwendet oder überprüft die Werte.
