The UIs are similar to plugins and reside in shared object +files in an LV2 bundle. UIs are associated with a plugin in RDF using the triples +
+@prefix ui: <http://lv2plug.in/ns/extensions/ui#> .
+
+<http://my.plugin>   ui:ui     <http://my.pluginui> .
+<http://my.pluginui> a         ui:GtkUI ;
+                     ui:binary <myui.so> .
+
+where <http://my.plugin> is the URI of the plugin, +<http://my.pluginui> is the URI of the plugin UI and <myui.so> +is the relative URI to the shared object file. + +While it is possible to have the plugin UI and the plugin in the same shared +object file it is probably a good idea to keep them separate so that hosts +that don't want UIs don't have to load the UI code. A UI MUST specify its +class in the RDF data (ui:GtkUI in the above example). The class defines what +type the UI is, e.g. what graphics toolkit it uses. Any type of UI class can +be defined separately from this extension. + +(Note: the prefix above is used throughout this file for the same URI) + +It is possible to have multiple UIs for the same plugin, or to have the UI +for a plugin in a different bundle from the actual plugin - this way people +other than the plugin author can write plugin UIs independently without +editing the original plugin bundle. + +Note that the process that loads the shared object file containing the UI +code and the process that loads the shared object file containing the actual +plugin implementation are not necessarily the same process (and not even +necessarily on the same machine). This means that plugin and UI code can +not use singletons and global variables and expect them to refer to +the same objects in the UI and the actual plugin. The function callback +interface defined in this header is the only method of communication between +UIs and plugin instances (extensions may define more, though this is +discouraged unless absolutely necessary since the significant benefits of +network transparency and serialisability are lost). + +Since the LV2 specification itself allows for extensions that may add new +functionality that could be useful to control with a UI, this extension +allows for meta-extensions that can extend the interface between the UI and +the host. These extensions mirror the extensions used for plugins - there are +required and optional "features" that you declare in the RDF data for the UI as +
+<http://my.pluginui> lv2:requiredFeature <http://my.feature> .
+<http://my.pluginui> lv2:optionalFeature <http://my.feature> .
+
+The rules for a UI with a required or optional feature are identical to those +of lv2:Plugin instances: if a UI declares a feature as required, the host is +NOT allowed to load it unless it supports that feature; and if it does support +a feature, it MUST pass an appropriate LV2_Feature struct to the UI's +instantiate() method. These features may be used to specify how to pass +specific types of data between the UI and the plugin port buffers +(see LV2UI_Write_Function for details). + +UIs written to this specification do not need to be threadsafe - the +functions defined below may only be called in the same thread the UI +main loop is running in. + +Note that this UI extension is NOT a lv2:Feature. There is no way for a +plugin to know whether the host that loads it supports UIs or not, and +the plugin must always work without the UI (although it may be rather +useless unless it has been configured using the UI in a previous session). +From the plugin perspective, control from a UI is the same as control +from anywhere else (e.g. the host, the user): via ports. + +A UI does not have to be a graphical widget, it could just as well be a +server listening for OSC input or an interface to some sort of hardware +device, depending on the RDF class of the UI. +""" . + + +ui:UI a rdfs:Class ; + rdfs:subClassOf lv2:Resource ; + rdfs:label "LV2 UI" ; + rdfs:comment "A UI for an LV2 plugin" . + +ui:GtkUI a rdfs:Class ; + rdfs:subClassOf ui:UI ; + rdfs:comment """ +A UI where the LV2_Widget is a pointer to a Gtk+ 2.0 compatible GtkWidget, +and the host guarantees that the Gtk+ library has been initialised and the +Glib main loop is running before an UI of this type is instantiated.""" . + +ui:makeSONameResident a lv2:Feature ; + rdfs:comment """ +This feature is ELF specific - it should only be used by UIs that +use the ELF file format for the UI shared object files (e.g. on Linux). +If it is required by an UI the UI should also list a number of SO names +(shared object names) for libraries that the UI shared object +depends on and that may not be unloaded during the lifetime of the host +process, using the predicate @c ui:residentSONames, like this: +
+<http://my.pluginui> ui:residentSONames "libgtkmm-2.4.so.1", "libfoo.so.0"
+
+The host MUST then make sure that the shared libraries with the given ELF +SO names are not unloaded when the plugin UI is, but stay loaded during +the entire lifetime of the host process.
