Any type of UI class can be defined +separately from this extension.</p> + +<p>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.</p> + +<p>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).</p> + +<p>UI functionality may be extended via features, much like plugins:</p> + +<pre class="turtle-code"> +<http://my.pluginui> lv2:requiredFeature <http://my.feature> . +<http://my.pluginui> lv2:optionalFeature <http://my.feature> . +</pre> + +<p>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.</p> + +<p>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.</p> + +<p>Note that UIs are completely separate from plugins.
