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:
创建纯红色画笔。
创建一个矩形,该矩形绑定椭圆。
填充屏幕上的省略号。
public:
void FillEllipseRectangle( PaintEventArgs^ e )
{
// Create solid brush.
SolidBrush^ redBrush = gcnew SolidBrush( Color::Red );
// Create rectangle for ellipse.
int x = 0;
int y = 0;
int width = 200;
int height = 100;
Rectangle rect = Rectangle(x,y,width,height);
// Fill ellipse on screen.
e->Graphics->FillEllipse( redBrush, rect );
}
public void FillEllipseRectangle(PaintEventArgs e)
{
// Create solid brush.
SolidBrush redBrush = new SolidBrush(Color.Red);
// Create rectangle for ellipse.
int x = 0;
int y = 0;
