+
    +where http://example.org/my-plugin is the URI of the plugin, +http://example.org/my-ui is the URI of the plugin UI and +my-ui.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 pui:UI, in this case pui-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 pui.h is +all you can expect to work.

    +""". + +############## +## UI Class ## +############## + +pui: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 pui: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_PUI_Widget object that is returned by the UIs +get_widget() function. For example, a type of pui-gtk:GtkGUI might tell the host +that LV2_PUI_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 its 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 pui.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: +

    + +

      +
    1. Which plugin port types the buffer type is valid for

    2. When the host should call port_event() in LV2_PUI_Descriptor

      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#> .
-  @prefix ui-gtk: <http://lv2plug.in/ns/ext/ui-gtk#> .
-  <http://example.org/my-ui>  a             ui-gtk:GtkUI ;
-                              lv2:appliesTo <http://example.org/my-plugin> ;
-                              ui:binary     <my-ui.so> .
-
      -where http://example.org/my-plugin is the URI of the plugin, -http://example.org/my-ui is the URI of the plugin UI and -my-ui.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 -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 its 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 -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: -
