[−][src]Trait gstreamer_editing_services::GESContainerExt
Required methods
fn add<P: IsA<TimelineElement>>(&self, child: &P) -> Result<(), BoolError>
[−]
Add the TimelineElement
to the container.
child
the TimelineElement
Returns
true
on success, false
on failure.
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>
Edit self
in the different exisiting EditMode
modes. In the case of
slide, and roll, you need to specify a Edge
layers
The layers you want the edit to
happen in, None
means that the edition is done in all the
GESLayers
contained in the current timeline.
new_layer_priority
The priority of the layer self
should land in.
If the layer you're trying to move the container to doesn't exist, it will
be created automatically. -1 means no move.
mode
The EditMode
in which the editition will happen.
edge
The Edge
the edit should happen on.
position
The position at which to edit self
(in nanosecond)
Returns
true
if the container as been edited properly, false
if an error
occured
fn get_children(&self, recursive: bool) -> Vec<TimelineElement>
[−]
Get the list of TimelineElement
contained in self
The user is responsible for unreffing the contained objects
and freeing the list.
recursive
Whether to recursively get children in self
Returns
The list of
timeline element contained in self
.
fn remove<P: IsA<TimelineElement>>(&self, child: &P) -> Result<(), BoolError>
[−]
Release the child
from the control of self
.
child
the TimelineElement
to release
Returns
true
if the child
was properly released, else false
.
fn ungroup(&self, recursive: bool) -> Vec<Container>
[−]
Ungroups the TimelineElement
contained in this GESContainer,
creating new Container
containing those TimelineElement
apropriately.
recursive
Wether to recursively ungroup self
Returns
The list of
Container
resulting from the ungrouping operation
The user is responsible for unreffing the contained objects
and freeing the list.
fn get_property_height(&self) -> u32
[−]
The span of priorities which this container occupies.
fn connect_child_added<F: Fn(&Self, &TimelineElement) + 'static>(
&self,
f: F
) -> SignalHandlerId
[−]
&self,
f: F
) -> SignalHandlerId
Will be emitted after a child was added to container
.
Usually you should connect with g_signal_connect_after
as in the first emission stage, the signal emission might
get stopped internally.
element
the TimelineElement
that was added.
fn connect_child_removed<F: Fn(&Self, &TimelineElement) + 'static>(
&self,
f: F
) -> SignalHandlerId
[−]
&self,
f: F
) -> SignalHandlerId
Will be emitted after a child was removed from container
.
element
the TimelineElement
that was removed.
fn connect_property_height_notify<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId
&self,
f: F
) -> SignalHandlerId
