Sets the currently selected stop.

Parameters

index index of stop, where 0 corresponds to the first stop

See also: selectedStop()

Definition at line 136 of file qgsgradientstopeditor.cpp.

◆ setColor1

void QgsGradientStopEditor::setColor1 ( const QColor & color )

slot

Sets the color for the first stop.

Parameters

color new stop color

◆ setGradientRamp()

void QgsGradientStopEditor::setGradientRamp ( const QgsGradientColorRamp & ramp )

Sets the current ramp shown in the editor.

Parameters

ramp	color ramp

See also: gradientRamp()

Definition at line 60 of file qgsgradientstopeditor.cpp.

◆ setSelectedStopColor

void QgsGradientStopEditor::setSelectedStopColor ( const QColor & color )

slot

Sets the color for the current selected stop.

Parameters

color new stop color
