Detailed Description

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:

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.

Constructor & Destructor Documentation

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).

Definition at line 13513 of file qcustomplot.cpp.

References QCustomPlot::currentLayer(), mFont, mSelectedFont, QCPLayerable::setLayer(), and QCPLayoutElement::setMargins().

QCPPlotTitle	(	QCustomPlot *	parentPlot,
		const QString &	text
	)

explicit

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

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

QSize 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.)

Reimplemented from QCPLayoutElement.

References mFont, QCPLayoutElement::mMargins, and mText.

QSize 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.)

Reimplemented from QCPLayoutElement.

void 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.

See Also: setSelected, setSelectable

Referenced by setSelected().

double 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.

Reimplemented from QCPLayoutElement.

void setFont ( const QFont & font )

Sets the font of the title text.
