Definisi

Ruang nama:

System.Drawing

Rakitan:

System.Drawing.Common.dll

Paket:

System.Drawing.Common v9.0.0-preview.6.24327.6

Sumber:

StringFormat.cs

Mendapatkan perhentian tab untuk objek StringFormat ini.

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

Jumlah spasi antara awal baris teks dan perhentian tab pertama.

Mengembalikan

Single[]

Array jarak (dalam jumlah spasi) di antara perhentian tab.

Contoh

Contoh berikut dirancang untuk digunakan dengan Windows Forms, dan memerlukan PaintEventArgse, yang merupakan parameter penanganan aktivitas Paint. Kode melakukan tindakan berikut:

• Mengatur perhentian tab dari StringFormat.

• Menggambar string dan persegi tata letak. Perhatikan bahwa string berisi tab. Pengaturan tab StringFormat menentukan offset teks bertab.

• Mendapatkan tab berhenti dan menggunakan atau memeriksa nilai.
