示例
下面的代码示例设计用于 Windows 窗体,它需要 PaintEventArgse
,这是 Paint 事件处理程序的参数。 该代码执行以下操作:
创建黑色笔。
创建矩形的位置和大小。
将矩形绘制到屏幕。
public:
void DrawRectangleInt( PaintEventArgs^ e )
{
// Create pen.
Pen^ blackPen = gcnew Pen( Color::Black,3.0f );
// Create location and size of rectangle.
int x = 0;
int y = 0;
int width = 200;
int height = 200;
// Draw rectangle to screen.
e->Graphics->DrawRectangle( blackPen, x, y, width, height );
}
public void DrawRectangleInt(PaintEventArgs e)
{
// Create pen.
Pen blackPen = new Pen(Color.Black, 3);
// Create location and size of rectangle.
int x = 0;
int y = 0;
int width = 200;
int height = 200;
// Draw rectangle to screen.
e.Graphics.DrawRectangle(blackPen, x, y, width, height);
}
Public Sub DrawRectangleInt(ByVal e As PaintEventArgs)
' Create pen.
Dim blackPen As New Pen(Color.Black, 3)
' Create location and size of rectangle.
Dim x As Integer = 0
Dim y As Integer = 0
Dim width As Integer = 200
Dim height As Integer = 200
' Draw rectangle to screen.
e.Graphics.DrawRectangle(blackPen, x, y, width, height)
End Sub
