Detailed Description#

The character format of text in a document specifies the visual properties of the text, as well as information about its role in a hypertext document.

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. setFontFamilies() and setFontPointSize() define the font’s family (e.g. Times) and printed size; setFontWeight() and setFontItalic() provide control over the style of the font. setFontUnderline() , setFontOverline() , setFontStrikeOut() , and 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() . The setAnchorHref() and setAnchorNames() functions are used to specify the information about the hyperlink’s destination and the anchor’s name.

class VerticalAlignment#

This enum describes the ways that adjacent characters can be vertically aligned.

Constant

Description

QTextCharFormat.AlignNormal

Adjacent characters are positioned in the standard way for text in the writing system in use.

QTextCharFormat.AlignSuperScript

Characters are placed above the base line for normal text.

QTextCharFormat.AlignSubScript

Characters are placed below the base line for normal text.

QTextCharFormat.AlignMiddle

The center of the object is vertically aligned with the base line. Currently, this is only implemented for inline objects.

QTextCharFormat.AlignBottom

The bottom edge of the object is vertically aligned with the base line.

QTextCharFormat.AlignTop

The top edge of the object is vertically aligned with the base line.

QTextCharFormat.AlignBaseline

The base lines of the characters are aligned.

class UnderlineStyle#

This enum describes the different ways drawing underlined text.

Constant

Description

QTextCharFormat.NoUnderline

Text is draw without any underlining decoration.

QTextCharFormat.SingleUnderline

A line is drawn using Qt::SolidLine.

QTextCharFormat.DashUnderline

Dashes are drawn using Qt::DashLine.

QTextCharFormat.DotLine

Dots are drawn using Qt::DotLine;

QTextCharFormat.DashDotLine

Dashes and dots are drawn using Qt::DashDotLine.

QTextCharFormat.DashDotDotLine

Underlines draw drawn using Qt::DashDotDotLine.

QTextCharFormat.WaveUnderline

The text is underlined using a wave shaped line.

QTextCharFormat.SpellCheckUnderline

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.

setAnchor(anchor)#
Parameters:

anchor – bool

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()

setAnchorHref(value)#
Parameters:

value – str

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()

setAnchorNames(names)#
Parameters:

names – list of strings

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()

setBaselineOffset(baseline)#
Parameters:

baseline – float

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.

setFont(font[, behavior=QTextCharFormat.FontPropertiesInheritanceBehavior.FontPropertiesAll])#
Parameters:

Sets the text format’s font.

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

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

setFontHintingPreference(hintingPreference)#
Parameters:

hintingPreferenceHintingPreference

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

setFontItalic(italic)#
Parameters:

italic – bool

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

setFontKerning(enable)#
Parameters:

enable – bool

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.

setFontLetterSpacing(spacing)#
Parameters:

spacing – float

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.

setFontLetterSpacingType(letterSpacingType)#
Parameters:

letterSpacingTypeSpacingType

Sets the letter spacing type of this format to letterSpacingType.

setFontOverline(overline)#
Parameters:

overline – bool

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

setFontPointSize(size)#
Parameters:

size – float

Sets the text format’s font size.

setFontStretch(factor)#
Parameters:

factor – int

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.
