* emitted the notify signal).

* whether the #GESTimelineElement:duration can be changed to the new

* value and to otherwise prepare the element in response to what the new

* %TRUE (normally because the method already handled setting the value,
|
|
* potentially to a snapped value, and emitted the notify signal).
|
|
* @set_inpoint: Method called just before the
|
|
* #GESTimelineElement:in-point is set to a new value. This method should
|
|
* not set the #GESTimelineElement:in-point itself, but should check
|
|
* whether it can be changed to the new value and to otherwise prepare the
|
|
* element in response to what the new value will be. A return of %FALSE
|
|
* means that the property should not be set.

|
|
* #GESTimelineElement:max-duration is set. This method should
|
|
* not set the #GESTimelineElement:max-duration itself, but should check
|
|
* whether it can be changed to the new value and to otherwise prepare the

|
* element in response to what the new value will be. A return of %FALSE
|
|
* means that the property should not be set.
|
|
* @set_priority: Method called just before the
|
|
* #GESTimelineElement:in-point is set.
|
|
* @ripple_end: Method to ripple an object on its #GES_EDGE_END edge.
|
|
* @roll_start: Method to roll an object on its #GES_EDGE_START edge.
|
|
* @roll_end: Method to roll an object on its #GES_EDGE_END edge.
|
|
* @trim: Method to trim an object.
|
|
* @deep_copy: Prepare @copy for pasting as a copy of @self. At least by
|
|
* copying the children properties of @self into @copy.
|
|
* @paste: Paste @self, which is the @copy prepared by @deep_copy, into
|
|
* the timeline at the given @paste_position, with @ref_element as a
|
|
* reference, which is the @self that was passed to @deep_copy.
|
|
* @lookup-child: Method to find a child with the child property.
|
|
* @prop_name. The default vmethod will return the first child that
|
|
* matches. Overwrite this with a call to the parent vmethod if you wish
|
|
* to redirect property names. Or overwrite to change which child is
|
|
* returned if multiple children share the same child property name.
|
|
* @get_track_types: Return a the track types for the element.
|
|
* @set_child_property: Method for setting the child property given by
|
|
* @pspec on @child to @value. Default implementation will use
|
|
* g_object_set_property().
|
|
* @get_layer_priority: Get the #GESLayer:priority of the layer that this
|
|
* element is part of.
|
|
* @list_children_properties: List the children properties that have been
|
|
* registered for the element. The default implementation is able to fetch
|
|
* all of these, so should be sufficient. If you overwrite this, you
|
|
* should still call the default implementation to get the full list, and
|
|
* then edit its content.
|
|
* @lookup_child: Find @child, and its registered child property @pspec,
|
|
* corresponding to the child property specified by @prop_name. The
|
|
* default implementation will search for the first child that matches. If
|
|
* you overwrite this, you will likely still want to call the default
|
|
* vmethod, which has access to the registered parameter specifications.
|
|
*
|
|
* The #GESTimelineElement base class. Subclasses should override at least
|
|
* @set_start @set_inpoint @set_duration @ripple @ripple_end @roll_start
|
|
* @roll_end and @trim.
|
|
*
|
|
* Vmethods in subclasses should apply all the operation they need to but
|
|
* the real method implementation is in charge of setting the proper field,
|
|
* and emitting the notify signal.
