public:
 static void DrawParentBackground(System::Drawing::Graphics ^ g, System::Drawing::Rectangle bounds, System::Windows::Forms::Control ^ childControl);

public static void DrawParentBackground (System.Drawing.Graphics g, System.Drawing.Rectangle bounds, System.Windows.Forms.Control childControl);

static member DrawParentBackground : System.Drawing.Graphics * System.Drawing.Rectangle * System.Windows.Forms.Control -> unit

Public Shared Sub DrawParentBackground (g As Graphics, bounds As Rectangle, childControl As Control)

매개 변수

g

Graphics

childControl의 부모에 대한 배경을 그리는 데 사용되는 Graphics입니다.

bounds

Rectangle

부모 컨트롤의 배경을 그릴 Rectangle입니다. 이 사각형은 자식 컨트롤의 범위 안에 있어야 합니다.

childControl

Control

부모의 배경을 그릴 컨트롤입니다.
