정의

비주얼 스타일을 사용하여 가로 스크롤 막대 트랙을 그립니다.

public:
 static void DrawRightHorizontalTrack(System::Drawing::Graphics ^ g, System::Drawing::Rectangle bounds, System::Windows::Forms::VisualStyles::ScrollBarState state);
public static void DrawRightHorizontalTrack (System.Drawing.Graphics g, System.Drawing.Rectangle bounds, System.Windows.Forms.VisualStyles.ScrollBarState state);
static member DrawRightHorizontalTrack : System.Drawing.Graphics * System.Drawing.Rectangle * System.Windows.Forms.VisualStyles.ScrollBarState -> unit
Public Shared Sub DrawRightHorizontalTrack (g As Graphics, bounds As Rectangle, state As ScrollBarState)

매개 변수

g
