Member Function Documentation

addRecentColor()

void QgsRecentColorScheme::addRecentColor ( const QColor &  color )

static

Adds a color to the list of recent colors.

Parameters

color

color to add

lastUsedColor()

Definition at line 69 of file qgscolorscheme.cpp.

clone()

QgsRecentColorScheme * QgsRecentColorScheme::clone ( ) const

overridevirtual

Clones a color scheme.

Returns

copy of color scheme

Implements QgsColorScheme.

Definition at line 64 of file qgscolorscheme.cpp.

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

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 45 of file qgscolorscheme.cpp.

flags()

SchemeFlags QgsRecentColorScheme::flags ( ) const

inlineoverridevirtual

Returns the current flags for the color scheme.

Returns

current flags

Reimplemented from QgsColorScheme.

Definition at line 226 of file qgscolorscheme.h.

lastUsedColor()

QColor QgsRecentColorScheme::lastUsedColor ( )

static

Returns the most recently used color.

See also

addRecentColor()

Definition at line 105 of file qgscolorscheme.cpp.

schemeName()

QString QgsRecentColorScheme::schemeName ( ) const

inlineoverridevirtual
