詳細描述

文檔中文本的字符格式指定文本的視覺特性,及在超文本文檔中其角色的有關信息。

The font used can be set by supplying a font to the setFont () function, and each aspect of its appearance can be adjusted to give the desired effect. setFontFamily () 和 setFontPointSize () define the font's family (e.g. Times) and printed size; setFontWeight () 和 setFontItalic () provide control over the style of the font. setFontUnderline (), setFontOverline (), setFontStrikeOut (),和 setFontFixedPitch () provide additional effects for text.

The color is set with setForeground (). If the text is intended to be used as an anchor (for hyperlinks), this can be enabled with setAnchor ()。 setAnchorHref () 和 setAnchorNames () functions are used to specify the information about the hyperlink's destination and the anchor's name.

enum QTextCharFormat:: FontPropertiesInheritanceBehavior

This enum specifies how the setFont () function should behave with respect to unset font properties.

常量 描述
QTextCharFormat::FontPropertiesSpecifiedOnly 0 If a property is not explicitly set, do not change the text format's property value.
QTextCharFormat::FontPropertiesAll 1 If a property is not explicitly set, override the text format's property with a default value.

該枚舉在 Qt 5.3 引入或被修改。

enum QTextCharFormat:: UnderlineStyle

This enum describes the different ways drawing underlined text.

常量 描述
QTextCharFormat::NoUnderline 0 Text is draw without any underlining decoration.
QTextCharFormat::SingleUnderline 1 A line is drawn using Qt::SolidLine .
QTextCharFormat::DashUnderline 2 Dashes are drawn using Qt::DashLine .
QTextCharFormat::DotLine 3 Dots are drawn using Qt::DotLine ;
QTextCharFormat::DashDotLine 4 Dashs and dots are drawn using Qt::DashDotLine .
QTextCharFormat::DashDotDotLine 5 Underlines draw drawn using Qt::DashDotDotLine .
QTextCharFormat::WaveUnderline 6 The text is underlined using a wave shaped line.
QTextCharFormat::SpellCheckUnderline 7 The underline is drawn depending on the SpellCheckUnderlineStyle theme hint of QPlatformTheme. By default this is mapped to WaveUnderline, on macOS it is mapped to DotLine.

該函數在 Qt 4.5 引入。

另請參閱 fontKerning () 和 setFont ().

void QTextCharFormat:: setFontLetterSpacing ( qreal spacing )

Sets the letter spacing of this format to the given spacing . The meaning of the value depends on the font letter spacing type.

設置文本格式的字體 size .

另請參閱 fontPointSize () 和 setFont ().

void QTextCharFormat:: setFontStretch ( int factor )

Sets the stretch factor for the font to factor .

The stretch factor changes the width of all characters in the font by factor percent. For example, setting factor to 150 results in all characters in the font being 1.5 times (ie. 150%) wider. The default stretch factor is 100. The minimum stretch factor is 1, and the maximum stretch factor is 4000.

拉伸因子僅應用於輪廓字體。位圖字體會忽略拉伸因子。

該函數在 Qt 5.0 引入。

另請參閱 fontStretch ().

void QTextCharFormat:: setFontStrikeOut ( bool strikeOut )

strikeOut is true, sets the text format's font with strike-out enabled (with a horizontal line through it); otherwise it is displayed without strikeout.

另請參閱 fontStrikeOut () 和 setFont ().
