create_extension

Description:

public Extension create_extension (PluginInfo info, Type extension_type, ...)

If the plugin identified by info implements the extension_type, then this function will return a new instance of this implementation.

When creating the new instance of the extension_type subtype, the provided construct properties will be passed to the extension construction handler (exactly like if you had called [ctor@GObject.Object.new] yourself).

Parameters:

this	A Engine.
info	A loaded PluginInfo.
extension_type	The implemented extension Type.
...	the value of the first property, followed optionally by more name/value pairs, followed by null.
first_property	the name of the first property.

Returns:

a new Object that implements extension_type; or null.
