Açıklamalar

sınıfı, GroupBoxRenderer grup kutusu denetimini işlemek için kullanılabilecek bir yöntem kümesi static sağlar. Denetimin işlenmesi, denetimin kullanıcı arabirimini çizmeyi ifade eder. Grup kutusu çizmek için yöntemlerden DrawGroupBox birini kullanın. Bu yöntemler çeşitli metin çizim seçenekleri sağlar.

İşletim sisteminde görsel stiller etkinleştirilirse ve görsel stilleri geçerli uygulamaya uygulanırsa, DrawGroupBox geçerli görsel stiliyle grup kutusunu çizer. Aksi takdirde, DrawGroupBox grup kutusunu klasik Windows stiliyle çizer. bu, işletim sisteminin geçerli görsel stili ayarıyla otomatik olarak eşleşmesi gereken özel bir denetim çiziyorsanız kullanışlıdır.

Bu sınıf, sınıfı tarafından kullanıma sunulan öğelerden birine ayarlanan bir System.Windows.Forms.VisualStyles.VisualStyleRenderer işlevini sarmalar System.Windows.Forms.VisualStyles.VisualStyleElement.Button.GroupBox . Daha fazla bilgi için bkz . Görsel Stiller ile Denetimleri İşleme.
