## Detailed Description

The QTextOption class provides a description of general rich text properties.

QTextOption is used to encapsulate common rich text properties in a single object. It contains information about text alignment, layout direction, word wrapping, and other standard properties associated with text rendering and layout.

See also QTextEdit, QTextDocument, and QTextCursor.

## Member Type Documentation

### enum QTextOption::Flag
flags QTextOption::Flags

Constant | Value | Description
--- | --- | ---
`QTextOption::IncludeTrailingSpaces` | `0x80000000` | When this option is set, QTextLine::naturalTextWidth() and naturalTextRect() will return a value that includes the width of trailing spaces in the text; otherwise this width is excluded.
`QTextOption::ShowTabsAndSpaces` | `0x1` | Visualize spaces with little dots, and tabs with little arrows.
`QTextOption::ShowLineAndParagraphSeparators` | `0x2` | Visualize line and paragraph separators with appropriate symbol characters.
`QTextOption::AddSpaceForLineAndParagraphSeparators` | `0x4` | While determining the line-break positions take into account the space added for drawing a separator character.
`QTextOption::SuppressColors` | `0x8` | Suppress all color changes in the character formats (except the main selection).

The Flags type is a typedef for QFlags<Flag>. It stores an OR combination of Flag values.

### enum QTextOption::TabType

This enum holds the different types of tabulator

Constant | Value | Description
--- | --- | ---
`QTextOption::LeftTab` | `0` | , A left-tab
`QTextOption::RightTab` | `1` | , A right-tab
`QTextOption::CenterTab` | `2` | , A centered-tab
`QTextOption::DelimiterTab` | `3` | A tab stopping at a certain delimiter-character

This enum was introduced in Qt 4.4.

### enum QTextOption::WrapMode

This enum describes how text is wrapped in a document.

Constant | Value | Description
--- | --- | ---
`QTextOption::NoWrap` | `0` | Text is not wrapped at all.
`QTextOption::WordWrap` | `1` | Text is wrapped at word boundaries.
`QTextOption::ManualWrap` | `2` | Same as QTextOption::NoWrap
`QTextOption::WrapAnywhere` | `3` | Text can be wrapped at any point on a line, even if it occurs in the middle of a word.
`QTextOption::WrapAtWordBoundaryOrAnywhere` | `4` | If possible, wrapping occurs at a word boundary; otherwise it will occur at the appropriate point on the line, even in the middle of a word.

## Member Function Documentation

### QTextOption::QTextOption ()

Constructs a text option with default properties for text.

### QTextOption::QTextOption ( Qt::Alignment alignment )

Constructs a text option with the given alignment for text.

### QTextOption::QTextOption ( const QTextOption & other )

Construct a copy of the other text option.

### QTextOption::~QTextOption ()

Destroys the text option.

### Qt::Alignment QTextOption::alignment () const

Returns the text alignment defined by the option.

See also setAlignment().

### Flags QTextOption::flags () const

Returns the flags associated with the option.

See also setFlags().

### void QTextOption::setAlignment ( Qt::Alignment alignment )

Sets the option's text alignment to the specified alignment.

See also alignment().

### void QTextOption::setFlags ( Flags flags )

Sets the flags associated with the option to the given flags.

See also flags().

### void QTextOption::setTabArray ( QList<qreal> tabStops )

Sets the tab positions for the text layout to those specified by tabStops.

See also tabArray(), setTabStop(), and setTabs().

### void QTextOption::setTabStop ( qreal tabStop )

Sets the default distance in device units between tab stops to the value specified by tabStop.

See also tabStop(), setTabArray(), setTabs(), and tabs().

### void QTextOption::setTabs ( QList<Tab> tabStops )

Set the Tab properties to tabStops.

See also tabStop() and tabs().

### void QTextOption::setTextDirection ( Qt::LayoutDirection direction )

Sets the direction of the text layout defined by the option to the given direction.

See also textDirection().

### void QTextOption::setUseDesignMetrics ( bool enable )

If enable is true then the layout will use design metrics; otherwise it will use the metrics of the paint device (which is the default behavior).

See also useDesignMetrics().

### void QTextOption::setWrapMode ( WrapMode mode )

Sets the option's text wrap mode to the given mode.

See also wrapMode().

### QList<qreal> QTextOption::tabArray () const

Returns a list of tab positions defined for the text layout.

See also setTabArray() and tabStop().

### qreal QTextOption::tabStop () const

Returns the distance in device units between tab stops. Convenient function for the above method

See also setTabStop(), tabArray(), setTabs(), and tabs().

### QList<Tab> QTextOption::tabs () const

Returns a list of tab positions defined for the text layout.

This function was introduced in Qt 4.4.

See also tabStop(), setTabs(), and setTabStop().

### Qt::LayoutDirection QTextOption::textDirection () const

Returns the direction of the text layout defined by the option.

See also setTextDirection().

### bool QTextOption::useDesignMetrics () const

Returns true if the layout uses design rather than device metrics; otherwise returns false.

See also setUseDesignMetrics().

### WrapMode QTextOption::wrapMode () const

Returns the text wrap mode defined by the option.

See also setWrapMode().

### QTextOption & QTextOption::operator= ( const QTextOption & other )

Returns true if the text option is the same as the other text option; otherwise returns false.
