Detailed Description#

Model mappers allow the use of a QAbstractItemModel-derived model as a data source for a chart series, creating a connection between a QCandlestickSeries and the model object. A model mapper maintains an equal size across all QCandlestickSets .

Note

The model used must support adding and removing rows/columns and modifying the data of the cells.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property modelᅟ: QAbstractItemModel#

This property Defines the model that is used by the mapper..

Access functions:

model()
setModel()
Signal modelReplaced()

property seriesᅟ: QCandlestickSeries#

This property Defines the QCandlestickSeries object that is used by the mapper..

Note

All data in the series is discarded when it is set to the mapper. When a new series is specified, the old series is disconnected (preserving its data).

Access functions:

series()
setSeries()
Signal seriesReplaced()

__init__([parent=None])#

Parameters:: parent – QObject

Constructs a model mapper object as a child of parent.

close()#

Return type:: int

Returns the row/column of the model that contains the close values of the sets in the series. Default value is -1 (invalid mapping).

See also

setClose()

firstSetSection()#

Return type:: int

Returns the section of the model that is used as the data source for the first candlestick set. Default value is -1 (invalid mapping).

See also

setFirstSetSection()

high()#

Return type:: int

Returns the row/column of the model that contains the high values of the sets in the series. Default value is -1 (invalid mapping).

See also

setHigh()

lastSetSection()#

Return type:: int

Returns the section of the model that is used as the data source for the last candlestick set. Default value is -1 (invalid mapping).

See also

setLastSetSection()

low()#

Return type:: int

Returns the row/column of the model that contains the low values of the sets in the series. Default value is -1 (invalid mapping).

See also

setLow()

model()#

Return type:: QAbstractItemModel

See also

setModel()

Getter of property modelᅟ .

modelReplaced()#

Emitted when the model, to which the mapper is connected, has changed.

See also

model

Notification signal of property modelᅟ .

open()#

Return type:: int

Returns the row/column of the model that contains the open values of the sets in the series. Default value is -1 (invalid mapping).

See also

setOpen()

abstract orientation()#

Return type:: Orientation

Returns the orientation that is used when QCandlestickModelMapper accesses the model. This determines whether the consecutive values of the set are read from rows (Qt::Horizontal) or from columns (Qt::Vertical).

series()#

Return type:: QCandlestickSeries

See also

setSeries()

Getter of property seriesᅟ .

seriesReplaced()#

Emitted when the series to which mapper is connected to has changed.

See also

series

Notification signal of property seriesᅟ .

setClose(close)#

Parameters:: close – int

Sets the row/column of the model that contains the close values of the sets in the series. Default value is -1 (invalid mapping).

See also

close()

setFirstSetSection(firstSetSection)#

Parameters:: firstSetSection – int

Sets the section of the model that is used as the data source for the first candlestick set. Parameter firstSetSection specifies the section of the model. Default value is -1.

See also

firstSetSection()

setHigh(high)#

Parameters:: high – int

Sets the row/column of the model that contains the high values of the sets in the series. Default value is -1 (invalid mapping).

See also

high()

setLastSetSection(lastSetSection)#

Parameters:: lastSetSection – int

Sets the section of the model that is used as the data source for the last candlestick set. Parameter lastSetSection specifies the section of the model. Default value is -1.

See also

lastSetSection()

setLow(low)#

Parameters:: low – int

Sets the row/column of the model that contains the low values of the sets in the series. Default value is -1 (invalid mapping).

low()

setModel(model)#

Parameters:: model – QAbstractItemModel

See also

model()

Setter of property modelᅟ .

setOpen(open)#

Parameters:: open – int

Sets the row/column of the model that contains the open values of the sets in the series. Default value is -1 (invalid mapping).

See also

open()

setSeries(series)#

Parameters:: series – QCandlestickSeries

See also

series()

Setter of property seriesᅟ .

setTimestamp(timestamp)#

Parameters:: timestamp – int

Sets the row/column of the model that contains the timestamp values of the sets in the series. Default value is -1 (invalid mapping).
