Opis szczegółowy

This is the standard legend item for plottables. It displays an icon of the plottable next to the plottable name. The icon is drawn by the respective plottable itself (QCPAbstractPlottable::drawLegendIcon), and tries to give an intuitive symbol for the plottable. For example, the QCPGraph draws a centered horizontal line and/or a single scatter point in the middle.

Legend items of this type are always associated with one plottable (retrievable via the plottable() function and settable with the constructor). You may change the font of the plottable name with setFont. Icon padding and border pen is taken from the parent QCPLegend, see QCPLegend::setIconBorderPen and QCPLegend::setIconTextPadding.

The function QCPAbstractPlottable::addToLegend/QCPAbstractPlottable::removeFromLegend creates/removes legend items of this type.

Since QCPLegend is based on QCPLayoutGrid, a legend item itself is just a subclass of QCPLayoutElement. While it could be added to a legend (or any other layout) via the normal layout interface, QCPLegend has specialized functions for handling legend items conveniently, see the documentation of QCPLegend.

Dokumentacja konstruktora i destruktora

QCPPlottableLegendItem::QCPPlottableLegendItem ( QCPLegend *  parent,
QCPAbstractPlottable *  plottable 
)

Creates a new legend item associated with plottable.

Once it's created, it can be added to the legend via QCPLegend::addItem.

A more convenient way of adding/removing a plottable to/from the legend is via the functions QCPAbstractPlottable::addToLegend and QCPAbstractPlottable::removeFromLegend.

Dokumentacja funkcji składowych

protectedvirtual

Implementuje QCPAbstractLegendItem.

QPen QCPPlottableLegendItem::getIconBorderPen ( ) const

QColor QCPPlottableLegendItem::getTextColor ( ) const

QSize QCPPlottableLegendItem::minimumOuterSizeHint ( ) const
protectedvirtual

Returns the suggested minimum size this layout element (the outerRect) may be compressed to, if no manual minimum size is set.

if a minimum size (setMinimumSize) was not set manually, parent layouts use the returned size (usually indirectly through QCPLayout::getFinalMinimumOuterSize) to determine the minimum allowed size of this layout element.

A manual minimum size is considered set if it is non-zero.

The default implementation simply returns the sum of the horizontal margins for the width and the sum of the vertical margins for the height. Reimplementations may use their detailed knowledge about the layout element's content to provide size hints.
