Remarks
A paragraph in a Microsoft Word document can be bulleted or numbered. When a paragraph is bulleted or numbered, it is said that list formatting is applied to the paragraph.
You do not create objects of the ListFormat class directly. You access ListFormat as a property of another object that can have list formatting associated with it. At the moment the objects that can have list formatting are: Paragraph, Style and DocumentBuilder.
ListFormat of a Paragraph specifies what list formatting and list level is applied to that particular paragraph.
ListFormat of a Style (applicable to paragraph styles only) allows to specify what list formatting and list level is applied to all paragraphs of that particular style.
ListFormat of a DocumentBuilder provides access to the list formatting at the current cursor position inside the DocumentBuilder.
The list formatting itself is stored inside a List object that is stored separately from the paragraphs. The list objects are stored inside a ListCollection collection. There is a single ListCollection collection per Document.
The paragraphs do not physically belong to a list. The paragraphs just reference a particular list object via the List property and a particular level in the list via the ListLevelNumber property. By setting these two properties you control what bullets and numbering is applied to a paragraph.
Examples
Shows how to work with list levels.
auto doc = MakeObject<Document>();
auto builder = MakeObject<DocumentBuilder>(doc);
ASSERT_FALSE(builder->get_ListFormat()->get_IsListItem());
// A list allows us to organize and decorate sets of paragraphs with prefix symbols and indents.
// We can create nested lists by increasing the indent level.
// We can begin and end a list by using a document builder's "ListFormat" property.
// Each paragraph that we add between a list's start and the end will become an item in the list.
// Below are two types of lists that we can create using a document builder.
// 1 - A numbered list:
// Numbered lists create a logical order for their paragraphs by numbering each item.
builder->get_ListFormat()->set_List(doc->get_Lists()->Add(ListTemplate::NumberDefault));
ASSERT_TRUE(builder->get_ListFormat()->get_IsListItem());
// By setting the "ListLevelNumber" property, we can increase the list level
// to begin a self-contained sub-list at the current list item.
// The Microsoft Word list template called "NumberDefault" uses numbers to create list levels for the first list level.
// Deeper list levels use letters and lowercase Roman numerals.
for (int i = 0; i < 9; i++)
{
builder->get_ListFormat()->set_ListLevelNumber(i);
builder->Writeln(String(u"Level ") + i);
}
// 2 - A bulleted list:
// This list will apply an indent and a bullet symbol ("•") before each paragraph.
// Deeper levels of this list will use different symbols, such as "■" and "○".
builder->get_ListFormat()->set_List(doc->get_Lists()->Add(ListTemplate::BulletDefault));
for (int i = 0; i < 9; i++)
{
builder->get_ListFormat()->set_ListLevelNumber(i);
builder->Writeln(String(u"Level ") + i);
}
// We can disable list formatting to not format any subsequent paragraphs as lists by un-setting the "List" flag.
builder->get_ListFormat()->set_List(nullptr);
ASSERT_FALSE(builder->get_ListFormat()->get_IsListItem());
doc->Save(ArtifactsDir + u"Lists.SpecifyListLevel.docx");
