Cursor.DrawStretched(Graphics, Rectangle) Cursor.DrawStretched(Graphics, Rectangle) Cursor.DrawStretched(Graphics, Rectangle) Cursor.DrawStretched(Graphics, Rectangle) Method

定義

在指定的表層和指定的範圍內,使用延伸格式繪製游標。Draws the cursor in a stretched format on the specified surface, within the specified bounds.

public:
 void DrawStretched(System::Drawing::Graphics ^ g, System::Drawing::Rectangle targetRect);
public void DrawStretched (System.Drawing.Graphics g, System.Drawing.Rectangle targetRect);
member this.DrawStretched : System.Drawing.Graphics * System.Drawing.Rectangle -> unit
Public Sub DrawStretched (g As Graphics, targetRect As Rectangle)

參數

g
Graphics Graphics Graphics Graphics

要繪製 CursorGraphics 表面。The Graphics surface on which to draw the Cursor.

targetRect
Rectangle Rectangle Rectangle Rectangle

Rectangle,表示 Cursor 的範圍。The Rectangle that represents the bounds of the Cursor.

範例

下列程式碼範例會以其一般大小,在表單上繪製指定的游標,而在延伸模式中則會將其大小的兩倍。The following code example draws the specified cursor on the form in its normal size, and in stretched mode, twice its size. 這個範例要求您必須有Form Cursor和物件,才能在呼叫它時將它傳入方法。This example requires that you have a Form and a Cursor object to pass into the method when it is called.

void DrawCursorsOnForm( System::Windows::Forms::Cursor^ cursor )
{
   
   // If the form's cursor is not the Hand cursor and the
   // Current cursor is the Default, Draw the specified
   // cursor on the form in normal size and twice normal size.
   if ( this->Cursor != Cursors::Hand && System::Windows::Forms::Cursor::Current == Cursors::Default )
   {
      
      // Draw the cursor stretched.
      Graphics^ graphics = this->CreateGraphics();
      Rectangle rectangle = Rectangle(Point(10,10),System::Drawing::Size( cursor->Size.Width * 2, cursor->Size.Height * 2 ));
      cursor->DrawStretched( graphics, rectangle );
      
      // Draw the cursor in normal size.
      rectangle.Location = Point(rectangle.Width + rectangle.Location.X,rectangle.Height + rectangle.Location.Y);
      rectangle.Size = cursor->Size;
      cursor->Draw( graphics, rectangle );
      
      // Dispose of the cursor.
      delete cursor;
   }
}
private void DrawCursorsOnForm(Cursor cursor)
{
   // If the form's cursor is not the Hand cursor and the 
   // Current cursor is the Default, Draw the specified 
   // cursor on the form in normal size and twice normal size.
   if(this.Cursor != Cursors.Hand & 
     Cursor.Current == Cursors.Default)
   {
      // Draw the cursor stretched.
      Graphics graphics = this.CreateGraphics();
      Rectangle rectangle = new Rectangle(
        new Point(10,10), new Size(cursor.Size.Width * 2, 
        cursor.Size.Height * 2));
      cursor.DrawStretched(graphics, rectangle);
		
      // Draw the cursor in normal size.
      rectangle.Location = new Point(
      rectangle.Width + rectangle.Location.X, 
        rectangle.Height + rectangle.Location.Y);
      rectangle.Size = cursor.Size;
      cursor.Draw(graphics, rectangle);

      // Dispose of the cursor.
      cursor.Dispose();
   }
}
Private Sub DrawCursorsOnForm(cursor As Cursor)
   ' If the form's cursor is not the Hand cursor and the 
   ' Current cursor is the Default, Draw the specified 
   ' cursor on the form in normal size and twice normal size. 
   If (Not Me.Cursor.Equals(Cursors.Hand)) And _
     Cursor.Current.Equals(Cursors.Default) Then

      ' Draw the cursor stretched.
      Dim graphics As Graphics = Me.CreateGraphics()
      Dim rectangle As New Rectangle(New Point(10, 10), _
        New Size(cursor.Size.Width * 2, cursor.Size.Height * 2))
      cursor.DrawStretched(graphics, rectangle)
     
      ' Draw the cursor in normal size.
      rectangle.Location = New Point(rectangle.Width + _
        rectangle.Location.X, rectangle.Height + rectangle.Location.Y)
      rectangle.Size = cursor.Size
      cursor.Draw(graphics, rectangle)

      ' Dispose of the cursor.
      cursor.Dispose()
   End If
End Sub

備註

Drawing 命令源自g參數所表示的圖形介面, Graphics但物件並未包含如何呈現指定影像的相關資訊,因此它會將呼叫Cursor傳遞給物件。The drawing command originates on the graphics surface represented by the g parameter, but a Graphics object does not contain information about how to render a given image, so it passes the call to the Cursor object. DrawStretched繪製游標時,方法會將影像Rectangle延伸,以填滿指定的。The DrawStretched method stretches the image to fill the specified Rectangle when the cursor is drawn.
