[−][src]Trait gstreamer_editing_services::prelude::GESContainerExt
Required methods
fn add<P: IsA<TimelineElement>>(&self, child: &P) -> Result<(), BoolError>
Adds a timeline element to the container. The element will now be a
child of the container (and the container will be the
TimelineElement:parent
of the added element), which means that it
is now controlled by the container. This may change the properties of
the child or the container, depending on the subclass.
Additionally, the children properties of the newly added element will
be shared with the container, meaning they can also be read and set
using TimelineElementExt::get_child_property
and
TimelineElementExt::set_child_property
on the container.
child
The element to add as a child
Returns
true
if child
was successfully added to self
.
fn edit(
&self,
layers: &[Layer],
new_layer_priority: i32,
mode: EditMode,
edge: Edge,
position: u64
) -> Result<(), BoolError>
&self,
layers: &[Layer],
new_layer_priority: i32,
mode: EditMode,
edge: Edge,
position: u64
) -> Result<(), BoolError>
Edits the container within its timeline.
Deprecated since 1.18
use TimelineElementExt::edit
instead.
layers
A whitelist of layers
where the edit can be performed, None
allows all layers in the
timeline
new_layer_priority
The priority/index of the layer self
should
be moved to. -1 means no move
mode
The edit mode
edge
The edge of self
where the edit should occur
position
The edit position: a new location for the edge of self
(in nanoseconds)
Returns
true
if the edit of self
completed, false
on failure.
fn get_children(&self, recursive: bool) -> Vec<TimelineElement>
Get the list of timeline elements contained in the container. If
recursive
is true
, and the container contains other containers as
children, then their children will be added to the list, in addition to
themselves, and so on.
recursive
Whether to recursively get children in self
Returns
The list of
TimelineElement
-s contained in self
.
fn remove<P: IsA<TimelineElement>>(&self, child: &P) -> Result<(), BoolError>
Removes a timeline element from the container. The element will no longer be controlled by the container.
child
The child to remove
Returns
true
if child
was successfully removed from self
.
fn ungroup(&self, recursive: bool) -> Vec<Container>
Ungroups the container by splitting it into several containers
containing various children of the original. The rules for how the
container splits depends on the subclass. A Group
will simply split
into its children. A Clip
will split into one Clip
per
TrackType
it overlaps with (so an audio-video clip will split into
an audio clip and a video clip), where each clip contains all the
TrackElement
-s from the original clip with a matching
TrackElement:track-type
.
If recursive
is true
, and the container contains other containers as
children, then they will also be ungrouped, and so on.
recursive
Whether to recursively ungroup self
Returns
The list of
new Container
-s created from the splitting of self
.
fn get_property_height(&self) -> u32
The span of the container's children's TimelineElement:priority
values, which is the number of integers that lie between (inclusive)
the minimum and maximum priorities found amongst the container's
children (maximum - minimum + 1).
fn connect_child_added<F: Fn(&Self, &TimelineElement) + 'static>(
&self,
f: F
) -> SignalHandlerId
&self,
f: F
) -> SignalHandlerId
Will be emitted after a child is added to the container. Usually,
you should connect with g_signal_connect_after
since the signal
may be stopped internally.
element
The child that was added
fn connect_child_removed<F: Fn(&Self, &TimelineElement) + 'static>(
&self,
f: F
) -> SignalHandlerId
&self,
f: F
) -> SignalHandlerId
fn connect_property_height_notify<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId
&self,
f: F
) -> SignalHandlerId
