屬性

範例

下列程式碼範例示範如何使用 SelectionBullet 屬性搭配 SelectionFontSelectedTextSelectionColor 屬性,在 控制項中 RichTextBox 建立項目符號清單。 這個範例會要求 RichTextBox 在表單上建立名為 richTextBox1 的控制項。

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

      // 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( "Arial",16 );
      richTextBox1->SelectedText = "Bulleted Text Complete!";
   }
private void WriteTextToRichTextBox()
{
   // Clear all text from the RichTextBox;
   richTextBox1.Clear();
   // 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("Arial", 16);
   richTextBox1.SelectedText = "Bulleted Text Complete!";
}
Private Sub WriteTextToRichTextBox()
   ' Clear all text from the RichTextBox;
   richTextBox1.Clear()
   ' 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("Arial", 16)
   richTextBox1.SelectedText = "Bulleted Text Complete!"
End Sub

備註

如果未選取任何文字,專案符號樣式會套用至目前的插入點,以及使用者于插入點之後輸入的所有段落。 專案符號樣式會套用至控制項的文字,直到移動插入點或使用者按下空專案符號專案的 Enter 鍵為止。

如果設定此屬性時在控制項內選取文字,選取文字中的所有段落都會轉換成項目符號清單中的專案符號專案。 您可以使用這個屬性,在控制項中 RichTextBox 建立的檔內建立項目符號清單。

屬性 BulletIndent 可讓您指定要在專案符號與專案符號專案文字之間套用的縮排數量。
