set_start

Description:

public virtual bool set_start (ClockTime start)

Sets start for the element.

If the element has a parent, this will also move its siblings with the same shift.

Whilst the element is part of a Timeline, this is the same as editing the element with edit under NORMAL with NONE. In particular, the start of the element may be snapped to a different timeline time from the one given. In addition, setting may fail if it would place the timeline in an unsupported configuration.

Parameters:

this	A TimelineElement
start	The desired start position of the element in its timeline

Returns:

true if start could be set for this.
