Aspose::Words::Lists::ListFormat::get_IsListItem method

ListFormat::get_IsListItem method

True when the paragraph has bulleted or numbered formatting applied to it.

bool Aspose::Words::Lists::ListFormat::get_IsListItem()

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++)
