Examples

Shows how to enable line numbering for a section.

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

// We can use the section's PageSetup object to display numbers to the left of the section's text lines.
// This is the same behavior as a List object,
// but it covers the entire section and does not modify the text in any way.
// Our section will restart the numbering on each new page from 1 and display the number,
// if it is a multiple of 3, at 50pt to the left of the line.
SharedPtr<PageSetup> pageSetup = builder->get_PageSetup();
pageSetup->set_LineStartingNumber(1);
pageSetup->set_LineNumberCountBy(3);
pageSetup->set_LineNumberRestartMode(LineNumberRestartMode::RestartPage);
pageSetup->set_LineNumberDistanceFromText(50.0);

for (int i = 1; i <= 25; i++)
{
    builder->Writeln(String::Format(u"Line {0}.", i));
}

// The line counter will skip any paragraph with the "SuppressLineNumbers" flag set to "true".
// This paragraph is on the 15th line, which is a multiple of 3, and thus would normally display a line number.
// The section's line counter will also ignore this line, treat the next line as the 15th,
// and continue the count from that point onward.
doc->get_FirstSection()->get_Body()->get_Paragraphs()->idx_get(14)->get_ParagraphFormat()->set_SuppressLineNumbers(true);

doc->Save(ArtifactsDir + u"PageSetup.LineNumbers.docx");
