QMediaTimeRange ¶

概要 ¶

详细描述 ¶

earliestTime() , latestTime() , intervals() and isEmpty() methods are used to get information about the current time range.

addInterval() , removeInterval() and clear() methods are used to modify the current time range.

When adding or removing intervals from the time range, existing intervals within the range may be expanded, trimmed, deleted, merged or split to ensure that all intervals within the time range remain distinct and disjoint. As a consequence, all intervals added or removed from a time range must be normal .

class QMediaTimeRange ¶

QMediaTimeRange(arg__1)

QMediaTimeRange(range)

QMediaTimeRange(start, end)

param range

QMediaTimeRange

param arg__1

QMediaTimeInterval

param start

qint64

param end

qint64

Constructs an empty time range.

Constructs a time range that contains an initial interval from start to end 包含在内。

If the interval is not normal , the resulting time range will be empty.

addInterval()

PySide2.QtMultimedia.QMediaTimeRange. addInterval ( interval ) ¶

参数

interval – QMediaTimeInterval

Adds the specified interval to the time range.

Adding intervals which are not normal is invalid, and will be ignored.

If the specified interval is adjacent to, or overlaps existing intervals within the time range, these intervals will be merged.

This operation takes linear time.

PySide2.QtMultimedia.QMediaTimeRange. addInterval ( start , end ) ¶

参数

• start – qint64

• end – qint64

这是重载函数。

Adds the interval specified by start and end to the time range.

PySide2.QtMultimedia.QMediaTimeRange. contains ( time ) ¶

参数

time – qint64

返回类型

bool

返回 true 若指定 time lies within the time range.

PySide2.QtMultimedia.QMediaTimeRange. intervals ( ) ¶

返回类型

Returns the list of intervals covered by this time range.

PySide2.QtMultimedia.QMediaTimeRange. isContinuous ( ) ¶

返回类型

bool

Returns true if the time range consists of a continuous interval. That is, there is one or fewer disjoint intervals within the time range.

PySide2.QtMultimedia.QMediaTimeRange. isEmpty ( ) ¶

返回类型

bool

Returns true if there are no intervals within the time range.

参数

interval – QMediaTimeInterval

移除指定 interval from the time range.

Removing intervals which are not normal is invalid, and will be ignored.

Intervals within the time range will be trimmed, split or deleted such that no intervals within the time range include any part of the target interval.

This operation takes linear time.
