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. Non-breaking spaces are shown differently to breaking spaces.

QTextOption::ShowLineAndParagraphSeparators

0x2

Visualize line and paragraph separators with appropriate symbol characters.

QTextOption::ShowDocumentTerminator

0x10

Visualize the end of the document with a section sign. This enum value was added in Qt 5.7.

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

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.

Constructs a text option with the given alignment for text. The word wrap property is set to QTextOption::WordWrap. The using of design metrics flag is set to false.

QTextOption::QTextOption(const QTextOption &other)

Construct a copy of the other text option.

QTextOption::~QTextOption()

Destroys the text option.

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

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

void QTextOption::setTabArray(const QList<qreal> &tabStops)

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