Required methods

fn copy(&self, deep: bool) -> Result<TimelineElement, BoolError>[src]

Create a copy of self. All the properties of self are copied into a new element, with the exception of property::TimelineElement::parent, property::TimelineElement::timeline and property::TimelineElement::name. Other data, such the list of a Container’s children, is not copied.

If deep is true, then the new element is prepared so that it can be used in paste() or TimelineExt::paste_element(). In the case of copying a Container, this ensures that the children of self will also be pasted. The new element should not be used for anything else and can only be used once in a pasting operation. In particular, the new element itself is not an actual ‘deep’ copy of self, but should be thought of as an intermediate object used for a single paste operation.

`deep`

Whether the copy is needed for pasting
