- lv2:documentation """ - -This extension makes it possible to create user interfaces for LV2 plugins. - -UIs are implemented as an LV2UI_Descriptor loaded via lv2ui_descriptor() in a -shared library, and are distributed in bundles just like plugins. - -UIs are associated with plugins in data: - - :::turtle - @prefix ui: <http://lv2plug.in/ns/extensions/ui#> . - - <http://my.plugin> ui:ui <http://my.pluginui> . - <http://my.pluginui> a ui:X11UI ; - lv2: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 a good idea to keep them separate so that hosts can avoid -loading the UI code if they do not need it. A UI MUST specify its class in the -RDF data (`ui:X11UI` in the above example). The class defines what type the UI -is, for example what graphics toolkit it uses. Any type of UI class can be -defined separately from this extension. - -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 allows plugin UIs -to be written independently. - -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 MUST 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). - -UI functionality may be extended via features, much like plugins: - - :::turtle - <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. This extension defines several standard features for -common functionality. - -UIs written to this specification do not need to be thread-safe. All functions -may only be called in the <q>UI thread</q>. There is only one UI thread (for -toolkits, the one the UI main loop runs in). There is no requirement that a -<q>UI</q> actually be a graphical widget. - -Note that UIs are completely separate from plugins. From the plugin's -perspective, control from a UI is indistinguishable from any other control, as -it all occurs via ports. - -"""^^lv2:Markdown . - -ui:GtkUI - lv2:documentation """ - -The host must guarantee that the Gtk+ 2 library has been initialised and the -Glib main loop is running before the UI is instantiated.

For -example, for a ui:X11UI, the parent should be a `Window`. This is particularly -useful for embedding, where the parent often must be known at construction time -for embedding to work correctly. - -UIs should not _require_ this feature unless it is necessary for them to work -at all, but hosts should provide it whenever possible. - -"""^^lv2:Markdown . - -ui:PortNotification - lv2:documentation """ - -This describes which ports the host must send notifications to the UI about. -The port must be specific either by index, using the ui:portIndex property, or -symbol, using the lv2:symbol property.
