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.
Константа | Значение | Описание |
---|---|---|
QTextOption::IncludeTrailingSpaces | 0x80000000 | Когда эта опция установлена, QTextLine::naturalTextWidth() и naturalTextRect() будут возвращать значение, которое включает в себя ширину концевых пробелов в тексте; в противном случае эта ширина исключается. |
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.
This enum holds the different types of tabulator
Константа | Значение | Описание |
---|---|---|
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 |
Данное перечисление было введено в Qt 4.4.
This enum describes how text is wrapped in a document.
Константа | Значение | Описание |
---|---|---|
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 default properties for text. The text alignment property is set to Qt::AlignLeft. The word wrap property is set to QTextOption::WordWrap. The using of design metrics flag is set to false.
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.
Construct a copy of the other text option.
Destroys the text option.
Returns the text alignment defined by the option.

Returns the flags associated with the option.
See also setFlags().
Sets the option's text alignment to the specified alignment.
Смотрите также alignment().
Sets the flags associated with the option to the given flags.
See also flags().
Sets the tab positions for the text layout to those specified by tabStops.
See also tabArray(), setTabStop(), and setTabs().
Sets the default distance in device units between tab stops to the value specified by tabStop.
See also tabStop(), setTabArray(), setTabs(), and tabs().
Set the Tab properties to tabStops.
See also tabStop() and tabs().
Sets the direction of the text layout defined by the option to the given direction.
See also textDirection().
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().
Sets the option's text wrap mode to the given mode.
See also wrapMode().
Returns a list of tab positions defined for the text layout.
See also setTabArray() and tabStop().
Returns the distance in device units between tab stops. Convenient function for the above method
See also setTabStop(), tabArray(), setTabs(), and tabs().
Returns a list of tab positions defined for the text layout.
Эта функция была введена в Qt 4.4.
See also tabStop(), setTabs(), and setTabStop().
Returns the direction of the text layout defined by the option.
See also setTextDirection().
Returns true if the layout uses design rather than device metrics; otherwise returns false.
See also setUseDesignMetrics().
Returns the text wrap mode defined by the option.
See also setWrapMode().
Returns true if the text option is the same as the other text option; otherwise returns false.
