详细描述
The QCandlestickSet class represents a single candlestick item in a candlestick chart.
Five values are needed to create a graphical representation of a candlestick item: open, high, low, close, and timestamp. These values can be either passed to a QCandlestickSet constructor or set by using setOpen(), setHigh(), setLow(), setClose(), and setTimestamp().

成员函数
QCandlestickSet::QCandlestickSet(qreal timestamp = 0.0, QObject *parent = nullptr)
Constructs a candlestick item with an optional timestamp and a parent.
QCandlestickSet::QCandlestickSet(qreal open, qreal high, qreal low, qreal close, qreal timestamp = 0.0, QObject *parent = nullptr)
Constructs a candlestick item with given ordered values. The values open, high, low, and close are mandatory. The values timestamp and parent are optional.
[virtual] QCandlestickSet::~QCandlestickSet()
Destroys the candlestick item.
[signal] void QCandlestickSet::brushChanged()
This signal is emitted when the candlestick item brush changes.
Note: Notifier signal for property brush.
参见 brush.
[signal] void QCandlestickSet::clicked()
This signal is emitted when the candlestick item is clicked.
[signal] void QCandlestickSet::closeChanged()
This signal is emitted when the candlestick item close value changes.
Note: Notifier signal for property close.
参见 close.
[signal] void QCandlestickSet::doubleClicked()
This signal is emitted when the user double-clicks a candlestick item.
[signal] void QCandlestickSet::highChanged()
This signal is emitted when the candlestick item high value changes.
Note: Notifier signal for property high.
参见 high.
[signal] void QCandlestickSet::hovered(bool status)
This signal is emitted when a mouse is hovered over a candlestick item.
When the mouse moves over the item, status turns true, and when the mouse moves away again, it turns false.
[signal] void QCandlestickSet::lowChanged()
This signal is emitted when the candlestick item low value changes.
Note: Notifier signal for property low.
参见 low.
[signal] void QCandlestickSet::openChanged()
This signal is emitted when the candlestick item open value changes.
Note: Notifier signal for property open.
参见 open.
[signal] void QCandlestickSet::penChanged()
This signal is emitted when the candlestick item pen changes.
Note: Notifier signal for property pen.
参见 pen.
[signal] void QCandlestickSet::pressed()
This signal is emitted when the user clicks the candlestick item and holds down the mouse button.
[signal] void QCandlestickSet::released()
This signal is emitted when the user releases the mouse press on the candlestick item.
[signal] void QCandlestickSet::timestampChanged()
This signal is emitted when the candlestick item timestamp changes.
Note: Notifier signal for property timestamp.
参见 timestamp.
