## Detailed Description

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().

See also QCandlestickSeries.

### 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.

See also 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.

See also 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.

See also 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.

See also low.

### `[signal]` void QCandlestickSet::openChanged()

This signal is emitted when the candlestick item open value changes.

Note: Notifier signal for property open.

See also open.

### `[signal]` void QCandlestickSet::penChanged()

This signal is emitted when the candlestick item pen changes.

Note: Notifier signal for property pen.

See also 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.

See also timestamp.
