Constructor & Destructor Documentation

◆ QgsProjectColorScheme()

QgsProjectColorScheme::QgsProjectColorScheme ( )
default

Constructor for QgsProjectColorScheme.

Member Function Documentation

◆ clone()

QgsProjectColorScheme * QgsProjectColorScheme::clone ( ) const
overridevirtual

Clones a color scheme.

Returns
copy of color scheme

Implements QgsColorScheme.

Definition at line 231 of file qgscolorscheme.cpp.

◆ fetchColors()

QgsNamedColorList QgsProjectColorScheme::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 194 of file qgscolorscheme.cpp.

◆ flags()

SchemeFlags QgsProjectColorScheme::flags ( ) const
inlineoverridevirtual

Returns the current flags for the color scheme.

Returns
current flags

Reimplemented from QgsColorScheme.

Definition at line 310 of file qgscolorscheme.h.

◆ isEditable()

bool QgsProjectColorScheme::isEditable ( ) const
inlineoverridevirtual

Returns whether the color scheme is editable.

Returns
true if scheme is editable
See also
setColors

Reimplemented from QgsColorScheme.

Definition at line 315 of file qgscolorscheme.h.

◆ schemeName()

QString QgsProjectColorScheme::schemeName ( ) const
inlineoverridevirtual

Gets the name for the color scheme.

Returns
color scheme name

Implements QgsColorScheme.

Definition at line 308 of file qgscolorscheme.h.

◆ setColors()

bool QgsProjectColorScheme::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
