Definition at line 256 of file qgstextformat.cpp.

◆ font()

QFont QgsTextFormat::font ( ) const

Returns the font used for rendering text.

Note that the size of the font is not used, and size() should be called instead to determine the size of rendered text.

See also: toQFont()

Since: QGIS 3.2

Definition at line 779 of file qgstextformat.cpp.

◆ isValid()

bool QgsTextFormat::isValid ( ) const

A default constructed QgsTextFormat is invalid, until at least one or more properties have been set on the format. An invalid state can be used as a representation of a "not set" text format, e.g. for indicating that a default text format should be used.

Note: Calling any setter on a QgsTextFormat object will automatically set the format as valid.

See also: setValid()

Since: QGIS 3.16

Definition at line 105 of file qgstextformat.cpp.

◆ lineHeight()

double QgsTextFormat::lineHeight ( ) const

Returns the line height for text.

If lineHeightUnit() is QgsUnitTypes::RenderPercentage (the default), then this is a number representing the leading between lines as a multiplier of line height (where 0 - 1.0 represents 0 to 100% of text line height). Otherwise the line height is an absolute measurement in lineHeightUnit().

See also: setLineHeight(); lineHeightUnit()

Definition at line 355 of file qgstextformat.cpp.

◆ lineHeightUnit()

Qgis::RenderUnit QgsTextFormat::lineHeightUnit ( ) const

Returns the size for rendered text.

Units are retrieved using sizeUnit().

See also: setSize(); sizeUnit()

Definition at line 289 of file qgstextformat.cpp.

◆ sizeMapUnitScale()

QgsMapUnitScale QgsTextFormat::sizeMapUnitScale ( ) const

Returns the map unit scale object for the size.

This is only used if the sizeUnit() is set to QgsUnitTypes::RenderMapUnit.

See also: setSizeMapUnitScale(); sizeUnit()

Definition at line 278 of file qgstextformat.cpp.

◆ sizeUnit()

Qgis::RenderUnit QgsTextFormat::sizeUnit ( ) const

Returns the units for the size of rendered text.

See also: size(); setSizeUnit(); sizeMapUnitScale()

Definition at line 267 of file qgstextformat.cpp.

◆ stretchFactor()

int QgsTextFormat::stretchFactor ( ) const

Returns the text's stretch factor.

The stretch factor matches a condensed or expanded version of the font or applies a stretch transform that changes the width of all characters in the font by factor percent.

For example, a factor of 150 results in all characters in the font being 1.5 times (ie. 150%) wider. The minimum stretch factor is 1, and the maximum stretch factor is 4000.

◆ textFormatPreviewPixmap()

QPixmap QgsTextFormat::textFormatPreviewPixmap	(	const QgsTextFormat &	format,
		QSize	size,
		const QString &	previewText = `QString()`,
		int	padding = `0`,
		const QgsScreenProperties &	screen = `QgsScreenProperties()`
	)

static

Returns a pixmap preview for a text format.

Parameters

format	text format
size	target pixmap size
previewText	text to render in preview, or empty for default text
padding	space between icon edge and color ramp
screen	can be used to specify the destination screen properties for the icon. This allows the icon to be generated using the correct DPI and device pixel ratio for the target screen (since QGIS 3.32)

◆ toMimeData()

QMimeData * QgsTextFormat::toMimeData ( ) const

Returns new mime data representing the text format settings.

Caller takes responsibility for deleting the returned object.

See also: fromMimeData()

Definition at line 763 of file qgstextformat.cpp.

◆ toQFont()

QFont QgsTextFormat::toQFont ( ) const

Returns a QFont matching the relevant settings from this text format.

Unlike font(), this method also handles the size and size units from the text format.

See also: fromQFont()

Since: QGIS 3.2

Definition at line 797 of file qgstextformat.cpp.

◆ updateDataDefinedProperties()

void QgsTextFormat::updateDataDefinedProperties ( QgsRenderContext & context )

Updates the format by evaluating current values of data defined properties.
