我想要一个自定义的 RichTextBox 控件以在 MS Word 等应用程序中使用。但挑战是对角输入文本。目前，我在 RichTextBox 的 Document 属性中使用 RichTextBox 和 TextEffect 来对角显示文本并且它可以工作。不幸的是，插入符号出现在其原始位置和方向，因此用户会混淆他编辑的内容、输入的位置和选择的内容。你能帮助我吗？

  <Style TargetType="Run">
    <Setter Property="TextEffects">
      <Setter.Value>
        <TextEffectCollection>
          <TextEffect PositionCount="99999">
            <TextEffect.Transform>
              <TransformGroup>
              <ScaleTransform/>
              <SkewTransform/>
              <RotateTransform Angle="30"/>
              <TranslateTransform X="30" Y="0"/>
            </TransformGroup>
          </TextEffect.Transform>
         </TextEffect>
       </TextEffectCollection>
      </Setter.Value>
    </Setter>
  </Style>
