Examples

Shows how to insert a TOC, and populate it with entries based on heading styles.

void FieldToc_()
{
    auto doc = MakeObject<Document>();
    auto builder = MakeObject<DocumentBuilder>(doc);

    builder->StartBookmark(u"MyBookmark");

    // Insert a TOC field, which will compile all headings into a table of contents.
    // For each heading, this field will create a line with the text in that heading style to the left,
    // and the page the heading appears on to the right.
    auto field = System::ExplicitCast<FieldToc>(builder->InsertField(FieldType::FieldTOC, true));

    // Use the BookmarkName property to only list headings
    // that appear within the bounds of a bookmark with the "MyBookmark" name.
    field->set_BookmarkName(u"MyBookmark");

    // Text with a built-in heading style, such as "Heading 1", applied to it will count as a heading.
    // We can name additional styles to be picked up as headings by the TOC in this property and their TOC levels.
    field->set_CustomStyles(u"Quote; 6; Intense Quote; 7");

    // By default, Styles/TOC levels are separated in the CustomStyles property by a comma,
    // but we can set a custom delimiter in this property.
    doc->get_FieldOptions()->set_CustomTocStyleSeparator(u";");

    // Configure the field to exclude any headings that have TOC levels outside of this range.
    field->set_HeadingLevelRange(u"1-3");

    // The TOC will not display the page numbers of headings whose TOC levels are within this range.
    field->set_PageNumberOmittingLevelRange(u"2-5");

    // Set a custom string that will separate every heading from its page number.

    InsertNewPageWithHeading(builder, u"Seventh entry", u"Heading 4");

    builder->EndBookmark(u"MyBookmark");
    builder->Writeln(u"Paragraph text.");

    // This entry does not appear because it is outside the bookmark specified by the TOC.
    InsertNewPageWithHeading(builder, u"Eighth entry", u"Heading 1");

    ASSERT_EQ(u" TOC  \\b MyBookmark \\t \"Quote; 6; Intense Quote; 7\" \\o 1-3 \\n 2-5 \\p - \\h \\x \\w", field->GetFieldCode());

    field->UpdatePageNumbers();
