Contoh

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

• Mengatur perhentian tab dari StringFormat.

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

• Mendapatkan tab berhenti dan menggunakan atau memeriksa nilai.

Keterangan

Setiap offset perhentian tab dalam tabStops array, kecuali yang pertama, relatif terhadap yang sebelumnya. Offset pemberhentian tab pertama relatif terhadap posisi offset awal yang ditentukan oleh firstTabOffset. Misalnya, jika posisi offset awal adalah 8 dan offset pemberhentian tab pertama adalah 50, maka perhentian tab pertama berada di posisi 58. Jika posisi offset awal adalah nol, maka offset pemberhentian tab pertama relatif terhadap posisi 0, asal string.
