Methods

MethodDescription
get_DisplayResult()Gets the text that represents the displayed field result.
get_End() constGets the node that represents the field end.
get_FieldEnd() constGets the node that represents the field end.
get_FieldStart() constGets the node that represents the start of the field.
get_Format()Gets a FieldFormat object that provides typed access to field’s formatting.
get_IsDirty()Gets whether the current result of the field is no longer correct (stale) due to other modifications made to the document.
get_IsLocked()Gets or sets whether the field is locked (should not recalculate its result).
get_LocaleId()Gets or sets the LCID of the field.
get_RemoveTrailingPeriod()Gets or sets whether to display the number without a trailing period.
get_Result()Gets or sets text that is between the field separator and field end.
get_Separator()Gets the node that represents the field separator. Can be null.
get_SeparatorCharacter()Gets or sets the separator character to be used.
get_Start() constGets the node that represents the start of the field.
virtual get_Type() constGets the Microsoft Word field type.
GetFieldCode()Returns text between field start and field separator (or field end if there is no separator). Both field code and field result of child fields are included.
GetFieldCode(bool)Returns text between field start and field separator (or field end if there is no separator).
GetType() const override
Is(const System::TypeInfo&) const override
Remove()Removes the field from the document. Returns a node right after the field. If the field’s end is the last child of its parent node, returns its parent paragraph. If the field is already removed, returns null.
set_IsDirty(bool)Sets whether the current result of the field is no longer correct (stale) due to other modifications made to the document.
set_IsLocked(bool)Setter for Aspose::Words::Fields::Field::get_IsLocked.
set_LocaleId(int32_t)Setter for Aspose::Words::Fields::Field::get_LocaleId.
set_RemoveTrailingPeriod(bool)Setter for Aspose::Words::Fields::FieldAutoNumLgl::get_RemoveTrailingPeriod.
set_Result(const System::String&)Setter for Aspose::Words::Fields::Field::get_Result.
set_SeparatorCharacter(const System::String&)Setter for Aspose::Words::Fields::FieldAutoNumLgl::get_SeparatorCharacter.
static Type()
Unlink()Performs the field unlink.
Update()Performs the field update. Throws if the field is being updated already.
Update(bool)Performs a field update. Throws if the field is being updated already.

Examples

Shows how to organize a document using AUTONUMLGL fields.

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

        String(u"Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. ") +

    // AUTONUMLGL fields display a number that increments at each AUTONUMLGL field within its current heading level.
    // These fields maintain a separate count for each heading level,
    // and each field also displays the AUTONUMLGL field counts for all heading levels below its own.
    // Changing the count for any heading level resets the counts for all levels above that level to 1.
    // This allows us to organize our document in the form of an outline list.
    // This is the first AUTONUMLGL field at a heading level of 1, displaying "1." in the document.
    InsertNumberedClause(builder, u"\tHeading 1", fillerText, StyleIdentifier::Heading1);

    // This is the second AUTONUMLGL field at a heading level of 1, so it will display "2.".

    // This is the first AUTONUMLGL field at a heading level of 2,
    // and the AUTONUMLGL count for the heading level below it is "2", so it will display "2.1.".
    InsertNumberedClause(builder, u"\tHeading 3", fillerText, StyleIdentifier::Heading2);

    // This field is at a heading level of 2, and its respective AUTONUMLGL count is at 2, so the field will display "2.2.".
    InsertNumberedClause(builder, u"\tHeading 5", fillerText, StyleIdentifier::Heading2);

    // Incrementing the AUTONUMLGL count for a heading level below this one
    // has reset the count for this level so that this field will display "2.2.1.".
