Public Shared ReadOnly Property Highlight As Pen

屬性值

Pen

Pen,為選取項目的背景色彩。

範例

下列程式代碼範例會使用針對這些類型定義的數個多載運算符來建立點和大小。 它也會示範如何使用 Highlight 屬性。

此範例的設計目的是要與 Windows Forms 搭配使用。 Create 包含具名 subtractButtonButton表單。 將程式代碼貼到表單中,並從表單的事件Paint處理方法呼叫 CreatePointsAndSizes 方法,並傳遞ePaintEventArgs

void CreatePointsAndSizes( PaintEventArgs^ e )
{
   // Create the starting point.
   Point startPoint = Point(subtractButton->Size);
   
   // Use the addition operator to get the end point.
   Point endPoint = startPoint + System::Drawing::Size( 140, 150 );
   
   // Draw a line between the points.
   e->Graphics->DrawLine( SystemPens::Highlight, startPoint, endPoint );
   
   // Convert the starting point to a size and compare it to the
   // subtractButton size.  
   System::Drawing::Size buttonSize = (System::Drawing::Size)startPoint;
   if ( buttonSize == subtractButton->Size )
   {
      e->Graphics->DrawString( "The sizes are equal.", gcnew System::Drawing::Font( this->Font,FontStyle::Italic ), Brushes::Indigo, 10.0F, 65.0F );
   }
}
private void CreatePointsAndSizes(PaintEventArgs e)
{

    // Create the starting point.
    Point startPoint = new Point(subtractButton.Size);

    // Use the addition operator to get the end point.
    Point endPoint = startPoint + new Size(140, 150);

    // Draw a line between the points.
    e.Graphics.DrawLine(SystemPens.Highlight, startPoint, endPoint);

    // Convert the starting point to a size and compare it to the
    // subtractButton size.  
    Size buttonSize = (Size)startPoint;
    if (buttonSize == subtractButton.Size)

        // If the sizes are equal, tell the user.
    {
        e.Graphics.DrawString("The sizes are equal.", 
            new Font(this.Font, FontStyle.Italic), 
            Brushes.Indigo, 10.0F, 65.0F);
    }
}
Private Sub CreatePointsAndSizes(ByVal e As PaintEventArgs)

    ' Create the starting point.
    Dim startPoint As New Point(subtractButton.Size)

    ' Use the addition operator to get the end point.
    Dim endPoint As Point = Point.op_Addition(startPoint, _
        New Size(140, 150))

    ' Draw a line between the points.
    e.Graphics.DrawLine(SystemPens.Highlight, startPoint, endPoint)

    ' Convert the starting point to a size and compare it to the
    ' subtractButton size.  
    Dim buttonSize As Size = Point.op_Explicit(startPoint)
    If (Size.op_Equality(buttonSize, subtractButton.Size)) Then

        ' If the sizes are equal, tell the user.
        e.Graphics.DrawString("The sizes are equal.", _
            New Font(Me.Font, FontStyle.Italic), _
            Brushes.Indigo, 10.0F, 65.0F)
    End If

End Sub

備註

選取的專案可能包含功能表項和選取的文字。 例如,畫筆可能是用於清單框中所選專案背景的色彩。
