pub struct MetaContainer { /* private fields */ }
Expand description
A glib::Object
that implements MetaContainer
can have metadata set on
it, that is data that is unimportant to its function within GES, but
may hold some useful information. In particular,
MetaContainerExt::set_meta()
can be used to store any glib::Value
under
any generic field (specified by a string key). The same method can also
be used to remove the field by passing None
. A number of convenience
methods are also provided to make it easier to set common value types.
The metadata can then be read with MetaContainerExt::meta()
and
similar convenience methods.
§Registered Fields
By default, any glib::Value
can be set for a metadata field. However, you
can register some fields as static, that is they only allow values of a
specific type to be set under them, using
MetaContainerExt::register_meta()
or
MetaContainerExt::register_static_meta()
. The set MetaFlag
will
determine whether the value can be changed, but even if it can be
changed, it must be changed to a value of the same type.
Internally, some GES objects will be initialized with static metadata
fields. These will correspond to some standard keys, such as
GES_META_VOLUME
.
§Signals
§notify-meta
This is emitted for a meta container whenever the metadata under one
of its fields changes, is set for the first time, or is removed. In
the latter case, value
will be None
.
