TextBoxBase.HorizontalOffset 属性

  • 参考

定义

命名空间:
System.Windows.Controls.Primitives
程序集:
PresentationFramework.dll

获取或设置水平滚动条位置。

public:
 property double HorizontalOffset { double get(); };
public double HorizontalOffset { get; }
member this.HorizontalOffset : double
Public ReadOnly Property HorizontalOffset As Double

属性值

Double

一个浮点值，该值指定水平滚动位置，以独立于设备的单位 (每单位 1/96 英寸) 。

设置此属性会导致文本编辑控件滚动到指定的水平偏移。 读取此属性将返回当前水平偏移。

如果文本编辑控件未配置为支持滚动，则此属性的值为 0.0。

此属性没有默认值。

例外

ArgumentException

尝试将此属性设置为负值。

示例

以下示例演示如何读取属性的值 HorizontalOffset 。

private void initValues(object sender, EventArgs e)
{
    myTB1.Text= "ExtentHeight is currently " + myTextBox.ExtentHeight.ToString();
    myTB2.Text= "ExtentWidth is currently " + myTextBox.ExtentWidth.ToString();
    myTB3.Text= "HorizontalOffset is currently " + myTextBox.HorizontalOffset.ToString();
    myTB4.Text= "VerticalOffset is currently " + myTextBox.VerticalOffset.ToString();
    myTB5.Text = "ViewportHeight is currently " + myTextBox.ViewportHeight.ToString();
    myTB6.Text = "ViewportWidth is currently " + myTextBox.ViewportWidth.ToString();
    radiobtn1.IsChecked = true;
}

Private Sub initValues(ByVal sender As Object, ByVal e As EventArgs)
    myTB1.Text = "ExtentHeight is currently " + myTextBox.ExtentHeight.ToString()
    myTB2.Text = "ExtentWidth is currently " + myTextBox.ExtentWidth.ToString()
    myTB3.Text = "HorizontalOffset is currently " + myTextBox.HorizontalOffset.ToString()
    myTB4.Text = "VerticalOffset is currently " + myTextBox.VerticalOffset.ToString()
    myTB5.Text = "ViewportHeight is currently " + myTextBox.ViewportHeight.ToString()
    myTB6.Text = "ViewportWidth is currently " + myTextBox.ViewportWidth.ToString()
    radiobtn1.IsChecked = True

注解

如果在从右向左模式工作，则从可见文本区域的右侧测量水平偏移量;否则，它从左侧进行度量。
