Aspose::Words::Lists::ListFormat::get_ListLevelNumber method

ListFormat::get_ListLevelNumber method

Gets or sets the list level number (0 to 8) for the paragraph.

int32_t Aspose::Words::Lists::ListFormat::get_ListLevelNumber()

Remarks

In Word documents, lists may consist of 1 or 9 levels, numbered 0 to 8.

Has effect only when the List property is set to reference a valid list.

// 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.
