QMediaTimeInterval ¶

概要 ¶

详细描述 ¶

An interval is specified by an inclusive start() and end() time. These must be set in the constructor, as this is an immutable class. The specific units of time represented by the class have not been defined - it is suitable for any times which can be represented by a signed 64 bit integer.

isNormal() method determines if a time interval is normal (a normal time interval has start() <= end() ). A normal interval can be received from an abnormal interval by calling the normalized() 方法。

contains() method determines if a specified time lies within the time interval.

translated() method returns a time interval which has been translated forwards or backwards through time by a specified offset.

class QMediaTimeInterval ¶

QMediaTimeInterval(arg__1)

QMediaTimeInterval(start, end)

param arg__1

QMediaTimeInterval

param start

qint64

param end

qint64

Constructs an empty interval.

Constructs an interval with the specified start and end times.

PySide2.QtMultimedia.QMediaTimeInterval. contains ( time ) ¶

参数

time – qint64

返回类型

bool

Returns true if the time interval contains the specified time . That is, start() <= time <= end() .

PySide2.QtMultimedia.QMediaTimeInterval. end ( ) ¶

返回类型

qint64

Returns the end time of the interval.

start()

PySide2.QtMultimedia.QMediaTimeInterval. isNormal ( ) ¶

返回类型

bool

Returns true if this time interval is normal. A normal time interval has start() <= end() .

normalized()

PySide2.QtMultimedia.QMediaTimeInterval. normalized ( ) ¶

返回类型

QMediaTimeInterval

Returns a normalized version of this interval.

若 start() time of the interval is greater than the end() time, then the returned interval has the start and end times swapped.

PySide2.QtMultimedia.QMediaTimeInterval. __ne__ ( arg__2 ) ¶

参数

arg__2 – QMediaTimeInterval

返回类型

bool

PySide2.QtMultimedia.QMediaTimeInterval. __eq__ ( arg__2 ) ¶

参数

arg__2 – QMediaTimeInterval

返回类型

bool

PySide2.QtMultimedia.QMediaTimeInterval. start ( ) ¶

返回类型

qint64

Returns the start time of the interval.

end()

PySide2.QtMultimedia.QMediaTimeInterval. translated ( offset ) ¶

参数

offset – qint64

返回类型

QMediaTimeInterval

Returns a copy of this time interval, translated by a value of offset . An interval can be moved forward through time with a positive offset, or backward through time with a negative offset.
