Detailed Description

\reentrant

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

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.

Member Enumeration Documentation

◆ Flag

enum QTextOption::Flag

\value IncludeTrailingSpaces 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.

\value ShowTabsAndSpaces Visualize spaces with little dots, and tabs with little arrows. Non-breaking spaces are shown differently to breaking spaces. \value ShowLineAndParagraphSeparators Visualize line and paragraph separators with appropriate symbol characters. \value [since 5.7] ShowDocumentTerminator Visualize the end of the document with a section sign. \value [since 6.9] ShowDefaultIgnorables Render normally non-visual characters if supported by font. \value AddSpaceForLineAndParagraphSeparators While determining the line-break positions take into account the space added for drawing a separator character. \value SuppressColors Suppress all color changes in the character formats (except the main selection). \value [since 6.9] DisableEmojiParsing By default, Qt will detect emoji sequences in input strings and prioritize using color fonts to display them. This extra step can be disabled by setting the DisableEmojiParsing flag if it is known in advance that it will not be needed.

◆ TabType

enum QTextOption::TabType

Since: 4.4

This enum holds the different types of tabulator

\value LeftTab A left-tab \value RightTab A right-tab \value CenterTab A centered-tab \value DelimiterTab A tab stopping at a certain delimiter-character

◆ WrapMode

enum QTextOption::WrapMode

This enum describes how text is wrapped in a document.

\value NoWrap Text is not wrapped at all. \value WordWrap Text is wrapped at word boundaries. \value ManualWrap Same as QTextOption::NoWrap \value WrapAnywhere Text can be wrapped at any point on a line, even if it occurs in the middle of a word. \value WrapAtWordBoundaryOrAnywhere 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.
