class | QCPLegend

## Descripción detallada

The abstract base class for all entries in a QCPLegend.

It defines a very basic interface for entries in a QCPLegend. For representing plottables in the legend, the subclass QCPPlottableLegendItem is more suitable.

Only derive directly from this class when you need absolute freedom (e.g. a custom legend entry that's not even associated with a plottable).

You must implement the following pure virtual functions:

- draw (from QCPLayerable)

You inherit the following members you may use:

QCPLegend *mParentLegend | A pointer to the parent QCPLegend.
QFont mFont | The generic font of the item. You should use this font for all or at least the most prominent text of the item.

## Documentación del constructor y destructor

QCPAbstractLegendItem::QCPAbstractLegendItem | ( | QCPLegend * | parent | ) |

explicit

Constructs a QCPAbstractLegendItem and associates it with the QCPLegend parent. This does not cause the item to be added to parent, so QCPLegend::addItem must be called separately.

## Documentación de las funciones miembro

void QCPAbstractLegendItem::selectionChanged | ( | bool | selected | ) |

signal

This signal is emitted when the selection state of this legend item has changed, either by user interaction or by a direct call to setSelected.

double QCPAbstractLegendItem::selectTest | ( | const QPointF & | pos,
|  | bool | onlySelectable,
|  | QVariant * | details = `0`
| ) |  | const

virtual

Layout elements are sensitive to events inside their outer rect. If pos is within the outer rect, this method returns a value corresponding to 0.99 times the parent plot's selection tolerance. However, layout elements are not selectable by default. So if onlySelectable is true, -1.0 is returned.

See QCPLayerable::selectTest for a general explanation of this virtual method.

QCPLayoutElement subclasses may reimplement this method to provide more specific selection test behaviour.

void QCPAbstractLegendItem::setFont | ( | const QFont & | font | ) |

Sets the default font of this specific legend item to font.

  setTextColor, QCPLegend::setFont

void QCPAbstractLegendItem::setSelectable | ( | bool | selectable | ) |

Sets whether this specific legend item is selectable.

Ver también
  setSelectedParts, QCustomPlot::setInteractions

void QCPAbstractLegendItem::setSelected | ( | bool | selected | ) |

Sets whether this specific legend item is selected.

It is possible to set the selection state of this item by calling this function directly, even if setSelectable is set to false.

  setSelectableParts, QCustomPlot::setInteractions

void QCPAbstractLegendItem::setSelectedFont | ( | const QFont & | font | ) |

When this legend item is selected, font is used to draw generic text, instead of the normal font set with setFont.

Ver también
  setFont, QCPLegend::setSelectedFont

void QCPAbstractLegendItem::setSelectedTextColor | ( | const QColor & | color | ) |

When this legend item is selected, color is used to draw generic text, instead of the normal color set with setTextColor.

  setTextColor, QCPLegend::setSelectedTextColor

void QCPAbstractLegendItem::setTextColor | ( | const QColor & | color | ) |

Sets the default text color of this specific legend item to color.
