## Descripción detallada

A layout element displaying a plot title text.

The text may be specified with setText, theformatting can be controlled with setFont and setTextColor.

A plot title can be added as follows:

customPlot->plotLayout()->insertRow(0); // inserts an empty row above the default axis rect
customPlot->plotLayout()->addElement(0, 0, new QCPPlotTitle(customPlot, "Your Plot Title"));

Since a plot title is a common requirement, QCustomPlot offers specialized selection signals for easy interaction with QCPPlotTitle. If a layout element of type QCPPlotTitle is clicked, the signal QCustomPlot::titleClick is emitted. A double click emits the QCustomPlot::titleDoubleClick signal.

## Documentación del constructor y destructor

QCPPlotTitle::QCPPlotTitle | ( | QCustomPlot * | parentPlot | ) |

explicit

Creates a new QCPPlotTitle instance and sets default values. The initial text is empty (setText).

To set the title text in the constructor, rather use QCPPlotTitle(QCustomPlot *parentPlot, const QString &text).

QCPPlotTitle::QCPPlotTitle | ( | QCustomPlot * | parentPlot,
|  | const QString & | text
| ) |  |

explicit

Esta es una función miembro sobrecargada que se suministra por conveniencia. Difiere de la anterior función solamente en los argumentos que acepta.

Creates a new QCPPlotTitle instance and sets default values. The initial text is set to text.

## Documentación de las funciones miembro

QSize QCPPlotTitle::maximumSizeHint | ( |  | ) | const

protectedvirtual

Returns the maximum size this layout element (the inner rect) may be expanded to.

if a maximum size (setMaximumSize) was not set manually, parent layouts consult this function to determine the maximum allowed size of this layout element. (A manual maximum size is considered set if it is smaller than Qt's QWIDGETSIZE_MAX.)

Reimplementado de QCPLayoutElement.

QSize QCPPlotTitle::minimumSizeHint | ( |  | ) | const

protectedvirtual

Returns the minimum size this layout element (the inner rect) may be compressed to.

if a minimum size (setMinimumSize) was not set manually, parent layouts consult this function to determine the minimum allowed size of this layout element. (A manual minimum size is considered set if it is non-zero.)

Reimplementado de QCPLayoutElement.

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

signal

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

Ver también
  setSelected, setSelectable

double QCPPlotTitle::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.

Reimplementado de QCPLayoutElement.

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

Sets the font of the title text.

Ver también
  setTextColor, setSelectedFont

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

Sets whether the user may select this plot title to selectable.

Note that even when selectable is set to `false`, the selection state may be changed programmatically via setSelected.

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

Sets the selection state of this plot title to selected. If the selection has changed, selectionChanged is emitted.

Note that this function can change the selection state independently of the current setSelectable state.

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

Sets the font of the title text that will be used if the plot title is selected (setSelected).

Ver también
  setFont

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

Sets the color of the title text that will be used if the plot title is selected (setSelected).

Ver también
  setTextColor

void QCPPlotTitle::setText | ( | const QString & | text | ) |

Sets the text that will be displayed to text. Multiple lines can be created by insertion of "\n".

Ver también
  setFont, setTextColor

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

Sets the color of the title text.

  setFont, setSelectedTextColor
