Opis szczegółowy

Each QCPAbstractPlottable instance has one QCPSelectionDecorator (accessible via QCPAbstractPlottable::selectionDecorator) and uses it when drawing selected segments of its data.

The selection decorator controls both pen (setPen) and brush (setBrush), as well as the scatter style (setScatterStyle) if the plottable draws scatters. Since a QCPScatterStyle is itself composed of different properties such as color shape and size, the decorator allows specifying exactly which of those properties shall be used for the selected data point, via setUsedScatterProperties.

A QCPSelectionDecorator subclass instance can be passed to a plottable via QCPAbstractPlottable::setSelectionDecorator, allowing greater customizability of the appearance of selected segments.

Use copyFrom to easily transfer the settings of one decorator to another one. This is especially useful since plottables take ownership of the passed selection decorator, and thus the same decorator instance can not be passed to multiple plottables.

Selection decorators can also themselves perform drawing operations by reimplementing drawDecoration, which is called by the plottable's draw method. The base class QCPSelectionDecorator does not make use of this however. For example, QCPSelectionDecoratorBracket draws brackets around selected data segments.

Copies all properties (e.g. color, fill, scatter style) of the other selection decorator to this selection decorator.

void QCPSelectionDecorator::drawDecoration ( QCPPainter *  painter, QCPDataSelection  selection  )

virtual

This method is called by all plottables' draw methods to allow custom selection decorations to be drawn. Use the passed painter to perform the drawing operations. selection carries the data selection for which the decoration shall be drawn.

The default base class implementation of QCPSelectionDecorator has no special decoration, so this method does nothing.

QCPScatterStyle QCPSelectionDecorator::getFinalScatterStyle

(

const QCPScatterStyle &

unselectedStyle

)

const

Returns the scatter style that the parent plottable shall use for selected scatter points. The plottable's original (unselected) scatter style must be passed as unselectedStyle. Depending on the setting of setUsedScatterProperties, the returned scatter style is a mixture of this selecion decorator's scatter style (setScatterStyle), and unselectedStyle.

Sets the brush that will be used by the parent plottable to draw selected data segments.

Sets the pen that will be used by the parent plottable to draw selected data segments.

void QCPSelectionDecorator::setScatterStyle	(	const QCPScatterStyle &	scatterStyle,
		QCPScatterStyle::ScatterProperties	usedProperties = QCPScatterStyle::spPen
	)

Sets the scatter style that will be used by the parent plottable to draw scatters in selected data segments.

usedProperties specifies which parts of the passed scatterStyle will be used by the plottable. The used properties can also be changed via setUsedScatterProperties.

void QCPSelectionDecorator::setUsedScatterProperties

(

const QCPScatterStyle::ScatterProperties &

properties

)

Use this method to define which properties of the scatter style (set via setScatterStyle) will be used for selected data segments. All properties of the scatter style that are not specified in properties will remain as specified in the plottable's original scatter style.
