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 pui: <http://lv2plug.in/ns/ext/pui#> .
-
-<http://example.org/my-ui>
-    a             pui:Gtk2UI ;
-    lv2:appliesTo <http://example.org/my-plugin> ;
-    pui: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 pui:UI, in this case pui:Gtk2UI. 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.

-""" . - -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:Gtk2UI 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. -

This port protocol defines a way for the host to send continuous peak -and RMS measurements of the audio signal at a certain port to the UI. The -intended use is visualisation, e.g. an animated meter widget that shows -the level of the audio input or output.

- -

A contiguous sequence of audio samples for which a single peak value -and a single RMS value have been computed is called a measurement -period.

The rules (see pui:PortProtocol) for this port protocol are:

-
    -
  1. This PortProtocol is valid for ports with the type lv2:AudioPort.
    2. -
  2. The host SHOULD call port_event() at regular intervals. The measurement - periods used for calls to port_event() for the same port SHOULD be - contiguous (i.e. the measurement period for one call should begin right - after the end of the measurement period for the previous call ends) unless - the UI has removed and re-added the port subscription between those calls. - However, UIs MUST NOT depend on either the regularity of the calls or the - contiguity of the measurement periods; hosts may change the call rate - or skip calls for performance or other reasons.

The class which represents a Gtk+ UI. For a successfully created instance of -an UI of this class, the get_widget() function MUST return a pointer to a valid -GtkWidget object compatible with Gtk+ version 2.0. The host MUST ensure that -the Gtk+ library has been initialised and that the Glib main loop is running -before an UI of this type is instantiated.

- -

Unless otherwise specified by extensions, all function pointers in -LV2_PUI_Descriptor may only be called from the thread that runs the Glib main -loop.

-""" . - -pui:noHostResize - a lv2:Feature ; - rdfs:label "No host resize" ; - lv2:documentation """ -

This Feature should only be used with UIs.

- -

When this Feature is active the host SHOULD NOT resize the UI widget to any -other size than its natural size, which the host should be able to determine -via the API of whatever toolkit the UI is implemented in. However, the UI MUST -NOT break if the widget is resized to another size. This Feature can be used -for example when the widget uses a fixed-size pixmap interface.

- -

The data pointer in the LV2_Feature object for this Feature should be set to -NULL.
