UI Show Interface (LV2_UI__showInterface)

UIs can provide this interface to show and hide a window, which allows them to function in hosts unable to embed their widget. This allows any UI to provide a fallback for embedding that works in any host.

If used: - The host MUST use LV2UI_Idle_Interface to drive the UI. - The UI MUST return non-zero from LV2UI_Idle_Interface::idle() when it has been closed. - If idle() returns non-zero, the host MUST call hide() and stop calling idle(). It MAY later call show() then resume calling idle().

Fields

The window title MAY have been passed by the host to LV2UI_Descriptor::instantiate() as an LV2_Options_Option with key LV2_UI__windowTitle.
