◆ clone()

QgsRecentColorScheme * QgsRecentColorScheme::clone ( ) const
overridevirtual

Clones a color scheme.

Returns
copy of color scheme

Implements QgsColorScheme.

◆ fetchColors()

QgsNamedColorList QgsRecentColorScheme::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.

Definition at line 42 of file qgscolorscheme.cpp.

SchemeFlags QgsRecentColorScheme::flags ( ) const
inlineoverridevirtual

Returns the current flags for the color scheme.
