DrawButton(Graphics, Rectangle, PushButtonState)

在指定的狀態和範圍中繪製按鈕控制項。

public:
 static void DrawButton(System::Drawing::Graphics ^ g, System::Drawing::Rectangle bounds, System::Windows::Forms::VisualStyles::PushButtonState state);

public static void DrawButton (System.Drawing.Graphics g, System.Drawing.Rectangle bounds, System.Windows.Forms.VisualStyles.PushButtonState state);

static member DrawButton : System.Drawing.Graphics * System.Drawing.Rectangle * System.Windows.Forms.VisualStyles.PushButtonState -> unit

Public Shared Sub DrawButton (g As Graphics, bounds As Rectangle, state As PushButtonState)

參數

g: Graphics

繪製按鈕所用的 Graphics。

bounds: Rectangle

指定按鈕繫結的 Rectangle。

state: PushButtonState

PushButtonState 的其中一個值，指定按鈕的可見狀態。

備註

如果在作業系統中啟用視覺化樣式，而視覺化樣式會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按鈕。否則，它會使用傳統 Windows 樣式繪製按鈕。
