public static void DrawRadioButton (System.Drawing.Graphics g, System.Drawing.Point glyphLocation, System.Windows.Forms.VisualStyles.RadioButtonState state);

Public Shared Sub DrawRadioButton (g As Graphics, glyphLocation As Point, state As RadioButtonState)

參數

g: Graphics

繪製選項按鈕所用的 Graphics。

glyphLocation: Point

要在上面繪製選項按鈕圖像的 Point。

state: RadioButtonState

其中一個 RadioButtonState 值，指定選項按鈕的可見狀態。

備註

如果在作業系統中啟用視覺化樣式，並將視覺化樣式套用至目前的應用程式，這個方法將會使用目前的視覺化樣式繪製選項按鈕。否則，此方法會使用傳統 Windows 樣式繪製選項按鈕。

範例

下列程式碼範例會在 DrawRadioButton(Graphics, Point, Rectangle, String, Font, Boolean, RadioButtonState) 自訂控制項的 OnPaint 方法中使用方法，在滑鼠指標的位置所決定的狀態中繪製選項按鈕。此程式碼範例是提供給類別之較大範例的 RadioButtonRenderer 一部分。
