      This extension defines an interface that can be used to create UIs for +plugins. The UIs are code that reside in shared object files in an LV2 +bundle and are referenced in the RDF data using the triples +

      +  @prefix ui: <http://lv2plug.in/ns/ext/ui#>.
+  <http://my.pluginui>  a             ui-gtk:GtkUI;
+                        lv2:appliesTo <http://my.plugin>;
+                        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 and the class MUST be a proper +subclass of ui:UI, in this case ui-gtk:GtkUI. The class defines what type the UI +is, e.g. what graphics toolkit it uses. There are no UI classes defined in +this extension, those are specified separately (and anyone can define their +own). +

      + +

      It's entirely 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. It is also possible to have one +UI that works with several different plugins. +

      + +

      UIs should also be written in such a way that the host may load several +instances of an UI, or different UIs, and use them with the same plugin +instance. +

      + +

      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 do not have to be the same. There are many +valid reasons for having the plugin and the UI in different processes, or +even on different machines. This means that you 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 the +header lv2_ui.h is all you can expect to work. +

      +""". + +############## +## UI Class ## +############## + +ui:UI a rdfs:Class; + rdfs:subClassOf lv2:Feature; + rdfs:label "UI"; + lv2:documentation """ +

      The class which represents an LV2 plugin UI. +

      + +

      To be used by a host a UI MUST have at least the following properties: +

      +    rdf:type (with object a proper subclass of ui:UI)
+    doap:name (one without language tag)
+    lv2:binary (with a shared object file as object)
+    lv2:appliesTo (with a LV2 plugin as object)
+
      +The rdf:type of an UI is used by the host to decide whether it supports the +UI and how to handle the LV2_UI_Widget object that is returned by the UIs +get_widget() function. For example, a type of ui-gtk:GtkGUI might tell the host +that LV2_UI_Widget is a pointer to an object of a type defined in the Gtk+ +library. No UI types are defined in this extension, that is intentionally +left for other extensions. +

      + +

      The doap:name property should be at most a few words in length using title +capitalization, e.g. "Flashy Mixer GUI". Use lv2:documentation for more +detailed descriptions.

      + +

      UIs may have optional or required features, specified using lv2:optionalFeature +or lv2:requiredFeature. The same rules apply here as for plugins; a host MUST +pass the LV2_Feature objects for all features it supports to the UI's +instantiate() function, a host SHOULD not try to instantiate an UI if it +doesn't support all of it's required features, and an UI MUST fail to +instantiate if the host doesn't pass all required features to instantiate(). +

      + +

      For details about the C API used to load UIs, see the file lv2_ui.h. +

      A PortProtocol defines a certain way of communicating port data between UI +and plugin. PortProtocols can be specified in additional extensions, and +those extensions MUST specify +

      + +

        +

      This extension defines an interface that can be used to create UIs for -plugins. The UIs are code that reside in shared object files in an LV2 -bundle and are referenced in the RDF data using the triples -

      -  @prefix ui: <http://lv2plug.in/ns/ext/ui#>.
-  <http://my.pluginui>  a             ui-gtk:GtkUI;
-                        lv2:appliesTo <http://my.plugin>;
-                        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 and the class MUST be a proper -subclass of ui:UI, in this case ui-gtk:GtkUI. The class defines what type the UI -is, e.g. what graphics toolkit it uses. There are no UI classes defined in -this extension, those are specified separately (and anyone can define their -own). -

      - -

      It's entirely 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. It is also possible to have one -UI that works with several different plugins. -

      - -

      UIs should also be written in such a way that the host may load several -instances of an UI, or different UIs, and use them with the same plugin -instance. -

      - -

      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 do not have to be the same. There are many -valid reasons for having the plugin and the UI in different processes, or -even on different machines. This means that you 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 the -header lv2_ui.h is all you can expect to work. -

      The class which represents an LV2 plugin UI. -

      - -

      To be used by a host a UI MUST have at least the following properties: -

      -    rdf:type (with object a proper subclass of ui:UI)
-    doap:name (one without language tag)
-    lv2:binary (with a shared object file as object)
-    lv2:appliesTo (with a LV2 plugin as object)
-
      -The rdf:type of an UI is used by the host to decide whether it supports the -UI and how to handle the LV2_UI_Widget object that is returned by the UIs -get_widget() function. For example, a type of ui-gtk:GtkGUI might tell the host -that LV2_UI_Widget is a pointer to an object of a type defined in the Gtk+ -library. No UI types are defined in this extension, that is intentionally -left for other extensions. -

      - -

      The doap:name property should be at most a few words in length using title -capitalization, e.g. "Flashy Mixer GUI". Use lv2:documentation for more -detailed descriptions.

      - -

      UIs may have optional or required features, specified using lv2:optionalFeature -or lv2:requiredFeature. The same rules apply here as for plugins; a host MUST -pass the LV2_Feature objects for all features it supports to the UI's -instantiate() function, a host SHOULD not try to instantiate an UI if it -doesn't support all of it's required features, and an UI MUST fail to -instantiate if the host doesn't pass all required features to instantiate(). -

      - -
