Returns true if the text is formatted as an anchor; otherwise returns false.

See also setAnchor(), setAnchorHref(), and setAnchorNames().

bool QTextCharFormat::isValid() const

Returns true if this character format is valid; otherwise returns false.

void QTextCharFormat::setAnchor(bool anchor)

If anchor is true, text with this format represents an anchor, and is formatted in the appropriate way; otherwise the text is formatted normally. (Anchors are hyperlinks which are often shown underlined and in a different color from plain text.)

The way the text is rendered is independent of whether or not the format has a valid anchor defined. Use setAnchorHref(), and optionally setAnchorNames() to create a hypertext link.

See also isAnchor().

void QTextCharFormat::setAnchorHref(const QString &value)

Sets the hypertext link for the text format to the given value. This is typically a URL like "http://example.com/index.html".

The anchor will be displayed with the value as its display text; if you want to display different text call setAnchorNames().

To format the text as a hypertext link use setAnchor().

See also anchorHref().

void QTextCharFormat::setAnchorNames(const QStringList &names)

Sets the text format's anchor names. For the anchor to work as a hyperlink, the destination must be set with setAnchorHref() and the anchor must be enabled with setAnchor().

See also anchorNames().

[since 6.0] void QTextCharFormat::setBaselineOffset(qreal baseline)

Sets the base line (in % of height) of text to baseline. A positive value moves the text up, by the corresponding %; a negative value moves it down. The default value is 0.

This function was introduced in Qt 6.0.

See also baselineOffset(), setSubScriptBaseline(), subScriptBaseline(), setSuperScriptBaseline(), and superScriptBaseline().

void QTextCharFormat::setFont(const QFont &font, QTextCharFormat::FontPropertiesInheritanceBehavior behavior = FontPropertiesAll)

Sets the text format's font.

If behavior is QTextCharFormat::FontPropertiesAll, the font property that has not been explicitly set is treated like as it were set with default value; If behavior is QTextCharFormat::FontPropertiesSpecifiedOnly, the font property that has not been explicitly set is ignored and the respective property value remains unchanged.

See also font().

void QTextCharFormat::setFontCapitalization(QFont::Capitalization capitalization)

Sets the capitalization of the text that appears in this font to capitalization.

A font's capitalization makes the text appear in the selected capitalization mode.

See also fontCapitalization().

void QTextCharFormat::setFontFamilies(const QStringList &families)

Sets the text format's font families.

See also fontFamilies() and setFont().

void QTextCharFormat::setFontFixedPitch(bool fixedPitch)

If fixedPitch is true, sets the text format's font to be fixed pitch; otherwise a non-fixed pitch font is used.

See also fontFixedPitch() and setFont().

void QTextCharFormat::setFontHintingPreference(QFont::HintingPreference hintingPreference)

Sets the hinting preference of the text format's font to be hintingPreference.

See also fontHintingPreference(), setFont(), and QFont::setHintingPreference().

void QTextCharFormat::setFontItalic(bool italic)

If italic is true, sets the text format's font to be italic; otherwise the font will be non-italic.

See also fontItalic() and setFont().

void QTextCharFormat::setFontKerning(bool enable)

Enables kerning for this font if enable is true; otherwise disables it.

When kerning is enabled, glyph metrics do not add up anymore, even for Latin text. In other words, the assumption that width('a') + width('b') is equal to width("ab") is not neccesairly true.

See also fontKerning() and 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.

For percentage spacing a value of 100 indicates default spacing; a value of 200 doubles the amount of space a letter takes.

See also fontLetterSpacing(), setFontLetterSpacingType(), and fontLetterSpacingType().

void QTextCharFormat::setFontLetterSpacingType(QFont::SpacingType letterSpacingType)

Sets the letter spacing type of this format to letterSpacingType.

See also fontLetterSpacingType(), setFontLetterSpacing(), and fontLetterSpacing().

void QTextCharFormat::setFontOverline(bool overline)

If overline is true, sets the text format's font to be overlined; otherwise the font is displayed non-overlined.

See also fontOverline() and setFont().

void QTextCharFormat::setFontPointSize(qreal size)

Sets the text format's font size.

See also fontPointSize() and 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.

The stretch factor is only applied to outline fonts. The stretch factor is ignored for bitmap fonts.

See also fontStretch().

void QTextCharFormat::setFontStrikeOut(bool strikeOut)

If 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.

See also fontStrikeOut() and setFont().

void QTextCharFormat::setFontStyleHint(QFont::StyleHint hint, QFont::StyleStrategy strategy = QFont::PreferDefault)

Sets the font style hint and strategy.

Qt does not support style hints on X11 since this information is not provided by the window system.

See also fontStyleHint(), setFont(), and QFont::setStyleHint().

void QTextCharFormat::setFontStyleName(const QString &styleName)

Sets the text format's font styleName.

See also fontStyleName(), setFont(), and QFont::setStyleName().

void QTextCharFormat::setFontStyleStrategy(QFont::StyleStrategy strategy)

Sets the font style strategy.

See also fontStyleStrategy(), setFont(), and QFont::setStyleStrategy().

void QTextCharFormat::setFontUnderline(bool underline)

If underline is true, sets the text format's font to be underlined; otherwise it is displayed non-underlined.

See also fontUnderline() and setFont().

void QTextCharFormat::setFontWeight(int weight)

Sets the text format's font weight to weight.

See also fontWeight(), setFont(), and QFont::Weight.
