DrawButton(Graphics, Rectangle, PushButtonState)

在指定边界内绘制指定状态的按钮控件。

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)

参数

g: Graphics

用于绘制按钮的 Graphics。

bounds: Rectangle

指定按钮边界的 Rectangle。

state: PushButtonState

PushButtonState 值之一，指定按钮的可视状态。

注解

如果在操作系统中启用了视觉样式，并且视觉样式应用于当前应用程序，则此方法将使用当前视觉样式绘制按钮。否则，它将使用经典 Windows 样式绘制按钮。
