Member Function Documentation

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 specifiying 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.

Returns the file path for the associated gpl palette file.

Returns
gpl file path

Implemented in QgsUserColorScheme.

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

Sets the colors for the scheme.

This method is only valid for editable color schemes.

Parameters
