Detailed Description

Stores information relating to individual block formatting.

These options encapsulate formatting options which override the default settings from a QgsTextFormat for individual text blocks.

Warning: This API is not considered stable and may change in future QGIS versions.

◆ QgsTextBlockFormat() [1/2]

QgsTextBlockFormat::QgsTextBlockFormat ( )

default

◆ QgsTextBlockFormat() [2/2]

QgsTextBlockFormat::QgsTextBlockFormat ( const QTextBlockFormat & format )

Constructor for QgsTextBlockFormat, based on the specified QTextBlockFormat format.

Member Function Documentation

◆ hasHorizontalAlignmentSet()

bool QgsTextBlockFormat::hasHorizontalAlignmentSet ( ) const

inline

Returns true if the format has an explicit horizontal alignment set.

If false is returned then the horizontal alignment will be inherited.

See also: setHasHorizontalAlignmentSet(); horizontalAlignment()

Definition at line 82 of file qgstextblockformat.h.

◆ horizontalAlignment()

Qgis::TextHorizontalAlignment QgsTextBlockFormat::horizontalAlignment ( ) const

inline

Returns the format horizontal alignment.

This property is only respected if hasHorizontalAlignmentSet() is true.

See also: hasHorizontalAlignmentSet(); setHorizontalAlignment()

Definition at line 102 of file qgstextblockformat.h.

◆ lineHeight()

double QgsTextBlockFormat::lineHeight ( ) const

Returns the line height in points, or NaN if the line height is not set and should be auto calculated.

Note: A format should have either lineHeight() or lineHeightPercentage() set, not both.

See also: lineHeightPercentage(); setLineHeight()

Since: QGIS 3.42

Definition at line 82 of file qgstextblockformat.cpp.

◆ lineHeightPercentage()

double QgsTextBlockFormat::lineHeightPercentage ( ) const

Returns the line height percentage size (as fraction of font size from 0.0 to 1.0), or NaN if the line height percentage is not set.

Note: A format should have either lineHeight() or lineHeightPercentage() set, not both.

See also: lineHeight(); setLineHeightPercentage()

Since: QGIS 3.42

Definition at line 92 of file qgstextblockformat.cpp.

◆ margins()

QgsMargins QgsTextBlockFormat::margins ( ) const

inline

Returns the block margins, in points.

See also: setMargins()

Since: QGIS 3.42

Definition at line 174 of file qgstextblockformat.h.

◆ overrideWith()

void QgsTextBlockFormat::overrideWith ( const QgsTextBlockFormat & other )

Override all the default/unset properties of the current block format with the settings from another format.

This will replace any default/unset existing settings with the settings from other.

Any settings which are default/unset in other will be left unchanged.

Parameters

other The format to override with.

Definition at line 59 of file qgstextblockformat.cpp.

◆ setHasHorizontalAlignmentSet()

void QgsTextBlockFormat::setHasHorizontalAlignmentSet ( bool set )

inline

Sets whether the format has an explicit horizontal alignment set.

If set is false then the horizontal alignment will be inherited.

See also: hasHorizontalAlignmentSet(); setHorizontalAlignment()

Definition at line 92 of file qgstextblockformat.h.

◆ setHorizontalAlignment()

void QgsTextBlockFormat::setHorizontalAlignment ( Qgis::TextHorizontalAlignment alignment )

inline

Sets the format horizontal alignment.

This property is only respected if hasHorizontalAlignmentSet() is true.

See also: hasHorizontalAlignmentSet(); horizontalAlignment()

Definition at line 112 of file qgstextblockformat.h.

◆ setLineHeight()

void QgsTextBlockFormat::setLineHeight ( double height )

Sets the font line height, in points.

Set height to NaN if the line height is not set and should be auto calculated.

Note: A format should have either lineHeight() or lineHeightPercentage() set, not both.

See also: lineHeight(); setLineHeightPercentage()

Since: QGIS 3.42

Definition at line 87 of file qgstextblockformat.cpp.

◆ setLineHeightPercentage()

void QgsTextBlockFormat::setLineHeightPercentage ( double height )

Sets the line height percentage height (as fraction of font size from 0.0 to 1.0).

Set height to NaN if the line height percentange is not set.

Note: A format should have either lineHeight() or lineHeightPercentage() set, not both.

See also: lineHeightPercentage(); setLineHeight()

Since: QGIS 3.42

Definition at line 97 of file qgstextblockformat.cpp.

◆ setMargins()

void QgsTextBlockFormat::setMargins ( const QgsMargins & margins )

inline

Sets the block margins, in points.

See also: margins()

Since: QGIS 3.42

Definition at line 182 of file qgstextblockformat.h.

◆ updateFontForFormat()

void QgsTextBlockFormat::updateFontForFormat	(	QFont &	font,
		const QgsRenderContext &	context,
		double	scaleFactor = `1.0`
	)		const

Updates the specified font in place, applying block formatting options which are applicable on a font level when rendered in the given context.

The optional scaleFactor parameter can specify a font size scaling factor. It is recommended to set this to QgsTextRenderer::calculateScaleFactorForFormat() 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.
