Constructor & Destructor Documentation

◆ QgsTextFragment() [1/2]

QgsTextFragment::QgsTextFragment	(	const QString &	text = `QString()`,
		const QgsTextCharacterFormat &	format = `QgsTextCharacterFormat()`
	)

explicit

Constructor for QgsTextFragment, with the specified text and optional character format.

Definition at line 20 of file qgstextfragment.cpp.

◆ QgsTextFragment() [2/2]

QgsTextFragment::QgsTextFragment ( const QTextFragment & fragment )

explicit

Constructor for QgsTextFragment, based on the specified QTextFragment fragment.

Definition at line 25 of file qgstextfragment.cpp.

Member Function Documentation

◆ applyCapitalization()

void QgsTextFragment::applyCapitalization ( QgsStringUtils::Capitalization capitalization )

Applies a capitalization style to the fragment's text.

Since: QGIS 3.16

Definition at line 63 of file qgstextfragment.cpp.

◆ characterFormat()

const QgsTextCharacterFormat& QgsTextFragment::characterFormat ( ) const

inline

Returns the character formatting for the fragment.

See also: setCharacterFormat()

Definition at line 68 of file qgstextfragment.h.

◆ horizontalAdvance()

double QgsTextFragment::horizontalAdvance	(	const QFont &	font,
		bool	fontHasBeenUpdatedForFragment = `false`,
		double	scaleFactor = `1.0`
	)		const

Returns the horizontal advance associated with this fragment, when rendered using the specified base font.

Set fontHasBeenUpdatedForFragment to true if font already represents the character format for this fragment.

The optional scaleFactor parameter can specify a font size scaling factor. It is recommended to set this to QgsTextRenderer::FONT_WORKAROUND_SCALE and then manually calculations based on the resultant font metrics. Failure to do so will result in poor quality text rendering at small font sizes.

Definition at line 47 of file qgstextfragment.cpp.

◆ setCharacterFormat()

void QgsTextFragment::setCharacterFormat ( const QgsTextCharacterFormat & format )

Sets the character format for the fragment.

See also: characterFormat()

Definition at line 42 of file qgstextfragment.cpp.

◆ setText()

void QgsTextFragment::setText ( const QString & text )

Sets the text content of the fragment.

See also: text()

Definition at line 37 of file qgstextfragment.cpp.

◆ text()

QString QgsTextFragment::text ( ) const

Returns the text content of the fragment.

See also: setText()
