Detailed Description

A legend item representing a plottable with an icon and the plottable name.

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.

Constructor & Destructor Documentation

◆ QCPPlottableLegendItem()

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.

Member Function Documentation

◆ draw()

void QCPPlottableLegendItem::draw ( QCPPainter * painter)
overrideprotectedvirtual

Draws the item with painter. The size and position of the drawn legend item is defined by the parent layout (typically a QCPLegend) and the minimumOuterSizeHint and maximumOuterSizeHint of this legend item.

Implements QCPAbstractLegendItem.

Definition at line 18971 of file qcustomplot.cpp.

◆ getFont()

QFont QCPPlottableLegendItem::getFont ( ) const
protected

Returns the font that shall be used to draw text, taking into account the selection state of this item.

Definition at line 18960 of file qcustomplot.cpp.

◆ getIconBorderPen()

QPen QCPPlottableLegendItem::getIconBorderPen ( ) const
protected

Returns the pen that shall be used to draw the icon border, taking into account the selection state of this item.

Definition at line 18940 of file qcustomplot.cpp.

◆ getTextColor()

QColor QCPPlottableLegendItem::getTextColor ( ) const
protected

Returns the text color that shall be used to draw text, taking into account the selection state of this item.

Definition at line 18950 of file qcustomplot.cpp.

◆ minimumOuterSizeHint()

QSize QCPPlottableLegendItem::minimumOuterSizeHint ( ) const
overrideprotectedvirtual

Calculates and returns the size of this item. This includes the icon, the text and the padding in between.

\seebaseclassmethod

Reimplemented from QCPLayoutElement.
