VisualStyleElement.TextBox.TextEdit.ReadOnly 属性

定义

获取表示只读文本框的视觉样式元素。

public:
 static property System::Windows::Forms::VisualStyles::VisualStyleElement ^ ReadOnly { System::Windows::Forms::VisualStyles::VisualStyleElement ^ get(); };
public static System.Windows.Forms.VisualStyles.VisualStyleElement ReadOnly { get; }
static member ReadOnly : System.Windows.Forms.VisualStyles.VisualStyleElement
Public Shared ReadOnly Property ReadOnly As VisualStyleElement

属性值

VisualStyleElement,它表示只读文本框。

示例

下面的代码示例演示如何使用 VisualStyleElement 属性返回的 ReadOnly 创建 VisualStyleRenderer 。 若要运行此示例,请将其粘贴到 Windows 窗体中。 处理窗体的 Paint 事件,并从Paint事件处理方法调用 DrawVisualStyleElementTextBoxTextEdit6 方法,作为 ePaintEventArgs传递。

public void DrawVisualStyleElementTextBoxTextEdit6(PaintEventArgs e)
{
    if (VisualStyleRenderer.IsElementDefined(
        VisualStyleElement.TextBox.TextEdit.ReadOnly))
    {
        VisualStyleRenderer renderer =
             new VisualStyleRenderer(VisualStyleElement.TextBox.TextEdit.ReadOnly);
        Rectangle rectangle1 = new Rectangle(10, 50, 50, 50);
        renderer.DrawBackground(e.Graphics, rectangle1);
        e.Graphics.DrawString("VisualStyleElement.TextBox.TextEdit.ReadOnly",
             this.Font, Brushes.Black, new Point(10, 10));
    }
    else
        e.Graphics.DrawString("This element is not defined in the current visual style.",
             this.Font, Brushes.Black, new Point(10, 10));
}
Public Sub DrawVisualStyleElementTextBoxTextEdit6(ByVal e As PaintEventArgs)
    If (VisualStyleRenderer.IsElementDefined( _
     VisualStyleElement.TextBox.TextEdit.ReadOnly)) Then
        Dim renderer As New VisualStyleRenderer _
          (VisualStyleElement.TextBox.TextEdit.ReadOnly)
        Dim rectangle1 As New Rectangle(10, 50, 50, 50)
        renderer.DrawBackground(e.Graphics, rectangle1)
        e.Graphics.DrawString("VisualStyleElement.TextBox.TextEdit.ReadOnly", _
          Me.Font, Brushes.Black, New Point(10, 10))
    Else
        e.Graphics.DrawString("This element is not defined in the current visual style.", _
          Me.Font, Brushes.Black, New Point(10, 10))
    End If
End Sub

注解

可以使用 VisualStyleElement 属性返回 ReadOnly 的 来创建 VisualStyleRenderer
