[virtual] QAbstractBarSeries::~QAbstractBarSeries()

Removes the abstract bar series and the bar sets owned by it.

bool QAbstractBarSeries::append(QBarSet *set)

Adds a set of bars specified by set to the bar series and takes ownership of it. If the set is null or it already belongs to the series, it will not be appended. Returns true if appending succeeded.

bool QAbstractBarSeries::append(QList<QBarSet *> sets)

Adds a list of bar sets specified by sets to a bar series and takes ownership of the sets. Returns true if all sets were appended successfully. If any of the sets is null or was previously appended to the series, nothing is appended and this function returns false. If any of the sets appears in the list more than once, nothing is appended and this function returns false.

QList<QBarSet *> QAbstractBarSeries::barSets() const

Returns a list of bar sets in a bar series. Keeps the ownership of the bar sets.

qreal QAbstractBarSeries::barWidth() const

Returns the width of the bars of the series.

Note: Getter function for property barWidth.

See also setBarWidth().

[signal] void QAbstractBarSeries::barsetsAdded(QList<QBarSet *> sets)

This signal is emitted when the bar sets specified by sets are added to the series.

See also append() and insert().

[signal] void QAbstractBarSeries::barsetsRemoved(QList<QBarSet *> sets)

This signal is emitted when the bar sets specified by sets are removed from the series.

See also remove().

void QAbstractBarSeries::clear()

Removes all bar sets from the series and permanently deletes them.

[signal] void QAbstractBarSeries::clicked(int index, QBarSet *barset)

This signal is emitted when the user clicks the bar specified by index in the bar set specified by barset.

int QAbstractBarSeries::count() const

Returns the number of bar sets in a bar series.

Note: Getter function for property count.

[signal] void QAbstractBarSeries::countChanged()

This signal is emitted when the number of bar sets is changed, for example by append() or remove().

Note: Notifier signal for property count.

[signal] void QAbstractBarSeries::doubleClicked(int index, QBarSet *barset)

This signal is emitted when the user double-clicks the bar specified by index in the bar set specified by barset.

[signal] void QAbstractBarSeries::hovered(bool status, int index, QBarSet *barset)

This signal is emitted when a mouse is hovered over the bar specified by index in the bar set specified by barset. When the mouse moves over the bar, status turns true, and when the mouse moves away again, it turns false.

bool QAbstractBarSeries::insert(int index, QBarSet *set)

Inserts a bar set specified by set to a series at the position specified by index and takes ownership of the set. If the set is null or already belongs to the series, it will not be appended. Returns true if inserting succeeds.

bool QAbstractBarSeries::isLabelsVisible() const

Returns the visibility of labels.

Note: Getter function for property labelsVisible.

[signal] void QAbstractBarSeries::labelsAngleChanged(qreal angle)

This signal is emitted when the angle of the value labels changes.

Note: Notifier signal for property labelsAngle.

[signal] void QAbstractBarSeries::labelsFormatChanged(const QString &format)

This signal is emitted when the format of data value labels changes.

Note: Notifier signal for property labelsFormat.

[signal] void QAbstractBarSeries::labelsPositionChanged(QAbstractBarSeries::LabelsPosition position)

This signal is emitted when the position of value labels changes.

Note: Notifier signal for property labelsPosition.

[signal] void QAbstractBarSeries::labelsPrecisionChanged(int precision)

This signal is emitted when the precision of the value labels changes.

Note: Notifier signal for property labelsPrecision.

[signal] void QAbstractBarSeries::labelsVisibleChanged()

This signal is emitted when the labels' visibility changes.

Note: Notifier signal for property labelsVisible.

See also isLabelsVisible() and setLabelsVisible().

[signal] void QAbstractBarSeries::pressed(int index, QBarSet *barset)

This signal is emitted when the user clicks the bar specified by index in the bar set specified by barset and holds down the mouse button.

[signal] void QAbstractBarSeries::released(int index, QBarSet *barset)

This signal is emitted when the user releases the mouse press on the bar specified by index in the bar set specified by barset.

bool QAbstractBarSeries::remove(QBarSet *set)

Removes the bar set specified by set from the series and permanently deletes it if the removal succeeds. Returns true if the set was removed.

void QAbstractBarSeries::setBarWidth(qreal width)

Sets the width of the bars of the series to width.

Note: Setter function for property barWidth.

See also barWidth().

void QAbstractBarSeries::setLabelsVisible(bool visible = true)

Sets the visibility of labels in a bar series to visible.

Note: Setter function for property labelsVisible.

See also isLabelsVisible().

bool QAbstractBarSeries::take(QBarSet *set)

Takes a single set from the series. Does not delete the bar set object.

Note: The series remains the barset's parent object. You must set the parent object to take full ownership.

Returns true if the take operation succeeds.
