Constructor & Destructor Documentation

◆ QgsProjectStyleSettings()

QgsProjectStyleSettings::QgsProjectStyleSettings ( QgsProject * project = nullptr )

Constructor for QgsProjectStyleSettings for the specified project.

Ownership is transferred to the project.

Definition at line 36 of file qgsprojectstylesettings.cpp.

◆ ~QgsProjectStyleSettings()

QgsProjectStyleSettings::~QgsProjectStyleSettings ( )

override

Definition at line 43 of file qgsprojectstylesettings.cpp.

Member Function Documentation

◆ addStyleDatabasePath()

void QgsProjectStyleSettings::addStyleDatabasePath ( const QString & path )

Adds a style database path to the project.

Paths can be either style .db databases, or .xml exports of style databases.

The file path added by this method must always be absolute paths. Depending on the project settings, they may be converted to relative paths when the project is saved.

See also: styleDatabasePaths(); setStyleDatabasePaths(); styleDatabasesChanged()

Definition at line 425 of file qgsprojectstylesettings.cpp.

◆ colorModel()

Qgis::ColorModel QgsProjectStyleSettings::colorModel ( ) const

Returns the project's color model.

This model is used as the default color model when selecting a color in the whole application. Any color defined in a different color model than the returned model will be converted to this color model when exporting a layout.

The color model defaults to Qgis::ColorModel::Rgb

See also: setColorModel()

Since: QGIS 3.40

Definition at line 530 of file qgsprojectstylesettings.cpp.

◆ colorSpace()

QColorSpace QgsProjectStyleSettings::colorSpace ( ) const

Returns the project's color space.

The project color's space will be added to PDF layout exports when it is defined (i.e. it is different from the default invalid QColorSpace).

The color space defaults to an invalid color space.

See also: setColorSpace()

Since: QGIS 3.40

Definition at line 580 of file qgsprojectstylesettings.cpp.

◆ combinedStyleModel()

QgsCombinedStyleModel * QgsProjectStyleSettings::combinedStyleModel ( )

Returns the combined style model which includes all style databases associated with the project.

This model also includes QgsStyle::defaultStyle().

Note: This is only available on builds based on Qt 5.13 or later.

See also: styles()

Definition at line 508 of file qgsprojectstylesettings.cpp.

◆ defaultColorRamp()

QgsColorRamp * QgsProjectStyleSettings::defaultColorRamp ( ) const

Returns the project default color ramp.

Returns: a color ramp pointer or nullptr if there is no default set

Note: the color ramp ownership is transferred to the caller

Definition at line 108 of file qgsprojectstylesettings.cpp.

◆ defaultSymbol()

QgsSymbol * QgsProjectStyleSettings::defaultSymbol ( Qgis::SymbolType symbolType ) const

Returns the project default symbol for a given type.

Parameters

symbolType the symbol type

Returns: a symbol pointer or nullptr if there is no default set

Note: the symbol ownership is transferred to the caller

Definition at line 52 of file qgsprojectstylesettings.cpp.

◆ defaultSymbolOpacity()

double QgsProjectStyleSettings::defaultSymbolOpacity ( ) const

inline

Returns the default symbol opacity.

Definition at line 116 of file qgsprojectstylesettings.h.

◆ defaultTextFormat()

QgsTextFormat QgsProjectStyleSettings::defaultTextFormat ( ) const

Returns the project default text format.

Note: if no default is defined, the returned format will be invalid

Definition at line 123 of file qgsprojectstylesettings.cpp.

◆ projectStyle()

QgsStyle * QgsProjectStyleSettings::projectStyle ( )

Returns the style database to use for project specific styles.

See also: setProjectStyle()

Definition at line 214 of file qgsprojectstylesettings.cpp.

◆ projectStyleChanged

void QgsProjectStyleSettings::projectStyleChanged ( )

signal

Emitted when the style returned by projectStyle() is changed.

Note: Not available in Python bindings

◆ randomizeDefaultSymbolColor()

bool QgsProjectStyleSettings::randomizeDefaultSymbolColor ( ) const

inline

Returns whether the default symbol fill color is randomized.

Definition at line 106 of file qgsprojectstylesettings.h.

◆ readXml()

bool QgsProjectStyleSettings::readXml	(	const QDomElement &	element,
		const QgsReadWriteContext &	context,
		Qgis::ProjectReadFlags	flags = Qgis::ProjectReadFlags() )

Reads the settings's state from a DOM element.

See also: writeXml()

Definition at line 219 of file qgsprojectstylesettings.cpp.

◆ removeProjectStyle()

void QgsProjectStyleSettings::removeProjectStyle ( )

Removes and deletes the project style database.

Since: QGIS 3.32

Definition at line 183 of file qgsprojectstylesettings.cpp.

◆ reset()

void QgsProjectStyleSettings::reset ( )

Resets the settings to a default state.

Definition at line 158 of file qgsprojectstylesettings.cpp.

◆ setColorModel()

void QgsProjectStyleSettings::setColorModel ( Qgis::ColorModel colorModel )

Set the project's color model to colorModel.

This sets the default color model used when selecting a color in the whole application. Any color defined in a different color model than the one specified here will be converted to this color model when exporting a layout.

If a color space has already been set and its color model differs from colorModel, the project color space will be reset to invalid one (This is only true if QGIS is built against Qt 6.8.0 or greater).

See also: setColorSpace() colorSpace()

The color model defaults to Qgis::ColorModel::Rgb

See also: colorModel()

Since: QGIS 3.40

Definition at line 513 of file qgsprojectstylesettings.cpp.

◆ setColorSpace()

void QgsProjectStyleSettings::setColorSpace ( const QColorSpace & colorSpace )

Set the project's current color space to colorSpace.

colorSpace must be a valid RGB or CMYK color space. The color space's ICC profile will be added as a project attached file.

The project color's space will be added to PDF layout exports when it is defined (i.e. it is different from the default invalid QColorSpace).

If a color model has already been set and it differs from colorSpace's color model, the project's color model is set to match the color space's color model (This is only true if QGIS is built against Qt 6.8.0 or greater).

See also: setColorModel() colorModel()

The color space defaults to an invalid color space.

See also: colorSpace()

Since: QGIS 3.40
