示例

下面的代码示例演示了如何使用属性SelectionBullet和BulletIndentSelectedTextSelectionFontSelectionColor属性在控件中创建RichTextBox项目符号列表。 此示例要求在 RichTextBox 窗体上创建一 richTextBox1 个名为控件。

private:
   void WriteTextToRichTextBox()
   {
      // Clear all text from the RichTextBox;
      richTextBox1->Clear();

      // Indent bulleted text 30 pixels away from the bullet.
      richTextBox1->BulletIndent = 30;

      // Set the font for the opening text to a larger Arial font;
      richTextBox1->SelectionFont = gcnew System::Drawing::Font( "Arial",16 );

      // Assign the introduction text to the RichTextBox control.
      richTextBox1->SelectedText = "The following is a list of bulleted items:\n";

      // Set the Font for the first item to a smaller size Arial font.
      richTextBox1->SelectionFont = gcnew System::Drawing::Font( "Arial",12 );

      // Specify that the following items are to be added to a bulleted list.
      richTextBox1->SelectionBullet = true;

      // Set the color of the item text.
      richTextBox1->SelectionColor = Color::Red;

      // Assign the text to the bulleted item.
      richTextBox1->SelectedText = "Apples"
      "\n";

      // Apply same font since font settings do not carry to next line.
      richTextBox1->SelectionFont = gcnew System::Drawing::Font( "Arial",12 );
      richTextBox1->SelectionColor = Color::Orange;
      richTextBox1->SelectedText = "Oranges"
      "\n";
      richTextBox1->SelectionFont = gcnew System::Drawing::Font( "Arial",12 );
      richTextBox1->SelectionColor = Color::Purple;
      richTextBox1->SelectedText = "Grapes"
      "\n";

      // End the bulleted list.
      richTextBox1->SelectionBullet = false;

      // Specify the font size and string for text displayed below bulleted list.
      richTextBox1->SelectionFont = gcnew System::Drawing::Font( "Verdana",10 );
      richTextBox1->SelectedText = "The bulleted text is indented 30 pixels from the bullet symbol using the BulletIndent property.\n";
   }

private void WriteTextToRichTextBox()
{
   // Clear all text from the RichTextBox;
   richTextBox1.Clear();
   // Indent bulleted text 30 pixels away from the bullet.
   richTextBox1.BulletIndent = 30;
   // Set the font for the opening text to a larger Arial font;
   richTextBox1.SelectionFont = new Font("Arial", 16);
   // Assign the introduction text to the RichTextBox control.
   richTextBox1.SelectedText = "The following is a list of bulleted items:\n";
   // Set the Font for the first item to a smaller size Arial font.
   richTextBox1.SelectionFont = new Font("Arial", 12);
   // Specify that the following items are to be added to a bulleted list.
   richTextBox1.SelectionBullet = true;
   // Set the color of the item text.
   richTextBox1.SelectionColor = Color.Red;
   // Assign the text to the bulleted item.
   richTextBox1.SelectedText = "Apples" + "\n";
   // Apply same font since font settings do not carry to next line.
   richTextBox1.SelectionFont = new Font("Arial", 12);
   richTextBox1.SelectionColor = Color.Orange;
   richTextBox1.SelectedText = "Oranges" + "\n";
   richTextBox1.SelectionFont = new Font("Arial", 12);
   richTextBox1.SelectionColor = Color.Purple;
   richTextBox1.SelectedText = "Grapes" + "\n";
   // End the bulleted list.
   richTextBox1.SelectionBullet = false;
   // Specify the font size and string for text displayed below bulleted list.
   richTextBox1.SelectionFont = new Font("Verdana", 10);
   richTextBox1.SelectedText = "The bulleted text is indented 30 pixels from the bullet symbol using the BulletIndent property.\n";
}

Private Sub WriteTextToRichTextBox()
   ' Clear all text from the RichTextBox;
   richTextBox1.Clear()
   ' Indent bulleted text 30 pixels away from the bullet.
   richTextBox1.BulletIndent = 30
   ' Set the font for the opening text to a larger Arial font;
   richTextBox1.SelectionFont = New Font("Arial", 16)
   ' Assign the introduction text to the RichTextBox control.
   RichTextBox1.SelectedText = "The following is a list of bulleted items:" + ControlChars.Cr
   ' Set the Font for the first item to a smaller size Arial font.
   richTextBox1.SelectionFont = New Font("Arial", 12)
   ' Specify that the following items are to be added to a bulleted list.
   richTextBox1.SelectionBullet = True
   ' Set the color of the item text.
   richTextBox1.SelectionColor = Color.Red
   ' Assign the text to the bulleted item.
   richTextBox1.SelectedText = "Apples" + ControlChars.Cr
   ' Apply same font since font settings do not carry to next line.
   richTextBox1.SelectionFont = New Font("Arial", 12)
   richTextBox1.SelectionColor = Color.Orange
   richTextBox1.SelectedText = "Oranges" + ControlChars.Cr
   richTextBox1.SelectionFont = New Font("Arial", 12)
   richTextBox1.SelectionColor = Color.Purple
   richTextBox1.SelectedText = "Grapes" + ControlChars.Cr
   ' End the bulleted list.
   richTextBox1.SelectionBullet = False
   ' Specify the font size and string for text displayed below bulleted list.
   richTextBox1.SelectionFont = New Font("Verdana", 10)
   richTextBox1.SelectedText = "The bulleted text is indented 30 pixels from the bullet symbol using the BulletIndent property." + ControlChars.Cr
End Sub

注解

若要将项目符号样式应用于文本段落，请将 SelectionBullet 属性设置为 true 该属性，然后将该属性设置为 BulletIndent 应缩进文本的像素数。 段落将应用项目符号样式，并在项目符号后具有指定的缩进量。 此属性仅影响控件文本中的当前段落和项目符号列表中的当前选定项目符号。 若要将不同的缩进级别应用于项目符号项的整个列表，必须在设置 BulletIndent 属性之前选择项目符号项的所有文本。
