Constructor & Destructor Documentation

QgsCustomColorScheme()

QgsCustomColorScheme::QgsCustomColorScheme ( )

default

Constructor for QgsCustomColorScheme.

Member Function Documentation

clone()

QgsCustomColorScheme * QgsCustomColorScheme::clone ( ) const

overridevirtual

Clones a color scheme.

Returns

copy of color scheme

Implements QgsColorScheme.

Definition at line 188 of file qgscolorscheme.cpp.

fetchColors()

QgsNamedColorList QgsCustomColorScheme::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

context	string 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.
baseColor	base 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 116 of file qgscolorscheme.cpp.

flags()

SchemeFlags QgsCustomColorScheme::flags ( ) const

inlineoverridevirtual

Returns the current flags for the color scheme.

Returns

current flags

Reimplemented from QgsColorScheme.

Definition at line 281 of file qgscolorscheme.h.

isEditable()

bool QgsCustomColorScheme::isEditable ( ) const

inlineoverridevirtual

Returns whether the color scheme is editable.

Returns

true if scheme is editable

setColors

Reimplemented from QgsColorScheme.

Definition at line 286 of file qgscolorscheme.h.

schemeName()

QString QgsCustomColorScheme::schemeName ( ) const

inlineoverridevirtual

Gets the name for the color scheme.

Returns

color scheme name

Implements QgsColorScheme.

Definition at line 279 of file qgscolorscheme.h.

setColors()

bool QgsCustomColorScheme::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

colors	list of colors for the scheme
context	to set colors for
baseColor	base color to set colors for

Returns

true if colors were set successfully
