## Detailed Description

The QTextListFormat class provides formatting information for lists in a QTextDocument.

A list is composed of one or more items, represented as text blocks. The list's format specifies the appearance of items in the list. In particular, it determines the indentation and the style of each item.

The indentation of the items is an integer value that causes each item to be offset from the left margin by a certain amount. This value is read with indent() and set with setIndent().

The style used to decorate each item is set with setStyle() and can be read with the style() function. The style controls the type of bullet points and numbering scheme used for items in the list. Note that lists that use the decimal numbering scheme begin counting at 1 rather than 0.

Style properties can be set to further configure the appearance of list items; for example, the ListNumberPrefix and ListNumberSuffix properties can be used to customize the numbers used in an ordered list so that they appear as (1), (2), (3), etc.:

     QTextListFormat listFormat;

     listFormat.setStyle(QTextListFormat.ListDecimal);
     listFormat.setNumberPrefix("(");
     listFormat.setNumberSuffix(")");

     cursor.insertList(listFormat);

## Type Documentation

### QTextListFormat.Style

This enum describes the symbols used to decorate list items:

Constant | Value | Description
--- | --- | ---
`QTextListFormat.ListDisc` | `-1` | a filled circle
`QTextListFormat.ListCircle` | `-2` | an empty circle
`QTextListFormat.ListSquare` | `-3` | a filled square
`QTextListFormat.ListDecimal` | `-4` | decimal values in ascending order
`QTextListFormat.ListLowerAlpha` | `-5` | lower case Latin characters in alphabetical order
`QTextListFormat.ListUpperAlpha` | `-6` | upper case Latin characters in alphabetical order
`QTextListFormat.ListLowerRoman` | `-7` | lower case roman numerals (supports up to 4999 items only)
`QTextListFormat.ListUpperRoman` | `-8` | upper case roman numerals (supports up to 4999 items only)

## Method Documentation

### QTextListFormat.__init__ (self)

Constructs a new list format object.

### QTextListFormat.__init__ (self, QTextListFormat)

### int QTextListFormat.indent (self)

Returns the list format's indentation. The indentation is multiplied by the QTextDocument.indentWidth property to get the effective indent in pixels.

See also setIndent().

### bool QTextListFormat.isValid (self)

Returns true if this list format is valid; otherwise returns false.

### QString QTextListFormat.numberPrefix (self)

Returns the list format's number prefix.

This function was introduced in Qt 4.8.

See also setNumberPrefix().

### QString QTextListFormat.numberSuffix (self)

Returns the list format's number suffix.

This function was introduced in Qt 4.8.

See also setNumberSuffix().

### QTextListFormat.setIndent (self, int aindent)

Sets the list format's indentation. The indentation is multiplied by the QTextDocument.indentWidth property to get the effective indent in pixels.

See also indent().

### QTextListFormat.setNumberPrefix (self, QString np)

Sets the list format's number prefix to the string specified by numberPrefix. This can be used with all sorted list types. It does not have any effect on unsorted list types.

The default prefix is an empty string.

This function was introduced in Qt 4.8.

See also numberPrefix().

### QTextListFormat.setNumberSuffix (self, QString ns)

Sets the list format's number suffix to the string specified by numberSuffix. This can be used with all sorted list types. It does not have any effect on unsorted list types.

The default suffix is ".".

This function was introduced in Qt 4.8.

See also numberSuffix().

### QTextListFormat.setStyle (self, Style astyle)

Sets the list format's style.

See also style() and Style.

### Style QTextListFormat.style (self)

Returns the list format's style.

See also setStyle() and Style.
