◆ QgsGplColorScheme()

QgsGplColorScheme::QgsGplColorScheme ( )
default

Constructor for QgsGplColorScheme.

Member Function Documentation

◆ fetchColors()

QgsNamedColorList QgsGplColorScheme::fetchColors ( const QString &  context = QString(),
const QColor &  baseColor = QColor() 
)
overridevirtual

Gets a list of colors from the scheme.

The colors can optionally be generated using the supplied context and base color.

Parameters
contextstring specifying an optional context for the returned colors. For instance, a "recent colors" scheme may filter returned colors by context so that colors used only in a "composer" context are returned.
baseColorbase color for the scheme's colors. Some color schemes may take advantage of this to filter or modify their returned colors to colors related to the base color.
Returns
a list of QPairs of color and color name

Implements QgsColorScheme.

◆ gplFilePath()

virtual QString QgsGplColorScheme::gplFilePath ( )
protectedpure virtual

Returns the file path for the associated gpl palette file.

Returns
gpl file path

Implemented in QgsUserColorScheme.

◆ setColors()

bool QgsGplColorScheme::setColors ( const QgsNamedColorList colors,
const QString &  context = QString(),
const QColor &  baseColor = QColor() 
)
overridevirtual

Sets the colors for the scheme.

This method is only valid for editable color schemes.

Parameters
colorslist of colors for the scheme
contextto set colors for
baseColorbase color to set colors for
Returns
true if colors were set successfully
